In the late 1960s, around the time the Transport Act of 1968 was being implemented along with various PTAs and PTEs, there was a flurry of activity in Liverpool, backed by the City Council, to develop a transport strategy for the city and the soon to be formed Metropolitan County of Merseyside. One key component of this was the development of sections of underground railways in Liverpool city centre that was designed to utilise existing, mostly third rail electrified, railways that would allow for two main outcomes.
Firstly, better penetration of the central area than the existing lines could offer - most notably in the case of Exchange station that was arguably on the northern fringe of the centre by building the 'Link' line from Moorfields through Central and on to the Garston lines. This cleverly made use of some tunnel sections that the 'Loop' line would free up as we shall see.
Secondly to improve capacity on the existing 'Wirral lines' that, using the original Mersey railway tunnel, terminated in a reversing tunnel at Central station. This was to be achieved by a single line 'loop' via Moorfields, Lime St and back to Central, that allowed 'through running' as well as better connections and that was complemented by a new birrowing junction to segregate the running lines under Birkenhead at Hamilton Square.
Backed by the DoE and the PTE the British Railways Board undertook the works for both schemes and work started in c1972 and mostly completed by 1977. Sadly, two other components of the wider scheme, the Edge Hill spur and the Outer Loop railway, were cancelled leaving just the third rail operated Wirral and Northern lines of today - with the City line out on something of a limb in many senses.
The network created by these works has been expanded, with some extensions and new stations, although some of the wider ambitions seen in these three publications are still discussed to this day.
This is the 'glossy' "Merseyside's new railways" that is undated but that I suspect I picked up c1975. Nor only does it show the main components of the scheme but it also, interestingly, gives some indication of the look and feel of the new tunnelled underground stations and platforms, along with an appearance of potential new rolling stock that looks a bit like the BR "PEP prototype units. The propsoed architectural finishes are very 'of their time' but show possible use of BR's 'corporate identity' in new sub-surface stations.
This leaflet was issued by BR and Merseyside Transport.

Just keep records as ina Garten does to see what works best for you....
No, this recipe is not Ina's. It is mine. And, I am sure I learned from my Mother and both Grandmas..
Sorry, I left it in the oven too long. The Macintosh apples turned to an extremely delicious apple sauce. I used to make the apples in a separate pan and take them out sooner.
My Menu Plans
I'm beginning to plan my dishes for the holidays. I don't need to test the recipes because I make them for most holidays. However, my memory is slipping, so it probably would be a good idea to do some test baking. I really do need to check baking times.
I first posted this photo in 2011, and I have baked these foods in this oven each year since.
This year I will remember to bake the apples separately, to check them frequently, and to take the remaining ones out when they are done. It's good to bake a bunch of each item in their pan so you can take out one at a time to taste. Also, You can keep the remaining ones in the fridge and reheat as needed. They keep well.
This year I must remember to take note of the best baking times for the apples, the acorn squash, and the yams!!
Asher, at the 5th Street Deli, makes marvelous Moroccan Baked Salmon. I think I will order a platter of that too. It's always delicious!

Fish, any of approximately 34,000 species of vertebrate animals (phylum Chordata) found in the fresh and salt waters of the world. Living species range from the primitive jawless lampreys and hagfishes through the cartilaginous sharks, skates, and rays to the abundant and diverse bony fishes. Most fish species are cold-blooded; however, one species, the opah (Lampris guttatus), is warm-blooded.
The term fish is applied to a variety of vertebrates of several evolutionary lines. It describes a life-form rather than a taxonomic group. As members of the phylum Chordata, fish share certain features with other vertebrates. These features are gill slits at some point in the life cycle, a notochord, or skeletal supporting rod, a dorsal hollow nerve cord, and a tail. Living fishes represent some five classes, which are as distinct from one another as are the four classes of familiar air-breathing animals—amphibians, reptiles, birds, and mammals. For example, the jawless fishes (Agnatha) have gills in pouches and lack limb girdles. Extant agnathans are the lampreys and the hagfishes. As the name implies, the skeletons of fishes of the class Chondrichthyes (from chondr, “cartilage,” and ichthyes, “fish”) are made entirely of cartilage. Modern fish of this class lack a swim bladder, and their scales and teeth are made up of the same placoid material. Sharks, skates, and rays are examples of cartilaginous fishes. The bony fishes are by far the largest class. Examples range from the tiny seahorse to the 450-kg (1,000-pound) blue marlin, from the flattened soles and flounders to the boxy puffers and ocean sunfishes. Unlike the scales of the cartilaginous fishes, those of bony fishes, when present, grow throughout life and are made up of thin overlapping plates of bone. Bony fishes also have an operculum that covers the gill slits.
The study of fishes, the science of ichthyology, is of broad importance. Fishes are of interest to humans for many reasons, the most important being their relationship with and dependence on the environment. A more obvious reason for interest in fishes is their role as a moderate but important part of the world’s food supply. This resource, once thought unlimited, is now realized to be finite and in delicate balance with the biological, chemical, and physical factors of the aquatic environment. Overfishing, pollution, and alteration of the environment are the chief enemies of proper fisheries management, both in fresh waters and in the ocean. (For a detailed discussion of the technology and economics of fisheries, see commercial fishing.) Another practical reason for studying fishes is their use in disease control. As predators on mosquito larvae, they help curb malaria and other mosquito-borne diseases.
Fishes are valuable laboratory animals in many aspects of medical and biological research. For example, the readiness of many fishes to acclimate to captivity has allowed biologists to study behaviour, physiology, and even ecology under relatively natural conditions. Fishes have been especially important in the study of animal behaviour, where research on fishes has provided a broad base for the understanding of the more flexible behaviour of the higher vertebrates. The zebra fish is used as a model in studies of gene expression.
There are aesthetic and recreational reasons for an interest in fishes. Millions of people keep live fishes in home aquariums for the simple pleasure of observing the beauty and behaviour of animals otherwise unfamiliar to them. Aquarium fishes provide a personal challenge to many aquarists, allowing them to test their ability to keep a small section of the natural environment in their homes. Sportfishing is another way of enjoying the natural environment, also indulged in by millions of people every year. Interest in aquarium fishes and sportfishing supports multimillion-dollar industries throughout the world.
Fishes have been in existence for more than 450 million years, during which time they have evolved repeatedly to fit into almost every conceivable type of aquatic habitat. In a sense, land vertebrates are simply highly modified fishes: when fishes colonized the land habitat, they became tetrapod (four-legged) land vertebrates. The popular conception of a fish as a slippery, streamlined aquatic animal that possesses fins and breathes by gills applies to many fishes, but far more fishes deviate from that conception than conform to it. For example, the body is elongate in many forms and greatly shortened in others; the body is flattened in some (principally in bottom-dwelling fishes) and laterally compressed in many others; the fins may be elaborately extended, forming intricate shapes, or they may be reduced or even lost; and the positions of the mouth, eyes, nostrils, and gill openings vary widely. Air breathers have appeared in several evolutionary lines.
Many fishes are cryptically coloured and shaped, closely matching their respective environments; others are among the most brilliantly coloured of all organisms, with a wide range of hues, often of striking intensity, on a single individual. The brilliance of pigments may be enhanced by the surface structure of the fish, so that it almost seems to glow. A number of unrelated fishes have actual light-producing organs. Many fishes are able to alter their coloration—some for the purpose of camouflage, others for the enhancement of behavioral signals.
Fishes range in adult length from less than 10 mm (0.4 inch) to more than 20 metres (60 feet) and in weight from about 1.5 grams (less than 0.06 ounce) to many thousands of kilograms. Some live in shallow thermal springs at temperatures slightly above 42 °C (100 °F), others in cold Arctic seas a few degrees below 0 °C (32 °F) or in cold deep waters more than 4,000 metres (13,100 feet) beneath the ocean surface. The structural and, especially, the physiological adaptations for life at such extremes are relatively poorly known and provide the scientifically curious with great incentive for study.
Almost all natural bodies of water bear fish life, the exceptions being very hot thermal ponds and extremely salt-alkaline lakes, such as the Dead Sea in Asia and the Great Salt Lake in North America. The present distribution of fishes is a result of the geological history and development of Earth as well as the ability of fishes to undergo evolutionary change and to adapt to the available habitats. Fishes may be seen to be distributed according to habitat and according to geographical area. Major habitat differences are marine and freshwater. For the most part, the fishes in a marine habitat differ from those in a freshwater habitat, even in adjacent areas, but some, such as the salmon, migrate from one to the other. The freshwater habitats may be seen to be of many kinds. Fishes found in mountain torrents, Arctic lakes, tropical lakes, temperate streams, and tropical rivers will all differ from each other, both in obvious gross structure and in physiological attributes. Even in closely adjacent habitats where, for example, a tropical mountain torrent enters a lowland stream, the fish fauna will differ. The marine habitats can be divided into deep ocean floors (benthic), mid-water oceanic (bathypelagic), surface oceanic (pelagic), rocky coast, sandy coast, muddy shores, bays, estuaries, and others. Also, for example, rocky coastal shores in tropical and temperate regions will have different fish faunas, even when such habitats occur along the same coastline.
Although much is known about the present geographical distribution of fishes, far less is known about how that distribution came about. Many parts of the fish fauna of the fresh waters of North America and Eurasia are related and undoubtedly have a common origin. The faunas of Africa and South America are related, extremely old, and probably an expression of the drifting apart of the two continents. The fauna of southern Asia is related to that of Central Asia, and some of it appears to have entered Africa. The extremely large shore-fish faunas of the Indian and tropical Pacific oceans comprise a related complex, but the tropical shore fauna of the Atlantic, although containing Indo-Pacific components, is relatively limited and probably younger. The Arctic and Antarctic marine faunas are quite different from each other. The shore fauna of the North Pacific is quite distinct, and that of the North Atlantic more limited and probably younger. Pelagic oceanic fishes, especially those in deep waters, are similar the world over, showing little geographical isolation in terms of family groups. The deep oceanic habitat is very much the same throughout the world, but species differences do exist, showing geographical areas determined by oceanic currents and water masses.
All aspects of the life of a fish are closely correlated with adaptation to the total environment, physical, chemical, and biological. In studies, all the interdependent aspects of fish, such as behaviour, locomotion, reproduction, and physical and physiological characteristics, must be taken into account.
Correlated with their adaptation to an extremely wide variety of habitats is the extremely wide variety of life cycles that fishes display. The great majority hatch from relatively small eggs a few days to several weeks or more after the eggs are scattered in the water. Newly hatched young are still partially undeveloped and are called larvae until body structures such as fins, skeleton, and some organs are fully formed. Larval life is often very short, usually less than a few weeks, but it can be very long, some lampreys continuing as larvae for at least five years. Young and larval fishes, before reaching sexual maturity, must grow considerably, and their small size and other factors often dictate that they live in a habitat different than that of the adults. For example, most tropical marine shore fishes have pelagic larvae. Larval food also is different, and larval fishes often live in shallow waters, where they may be less exposed to predators.
After a fish reaches adult size, the length of its life is subject to many factors, such as innate rates of aging, predation pressure, and the nature of the local climate. The longevity of a species in the protected environment of an aquarium may have nothing to do with how long members of that species live in the wild. Many small fishes live only one to three years at the most. In some species, however, individuals may live as long as 10 or 20 or even 100 years.
Fish behaviour is a complicated and varied subject. As in almost all animals with a central nervous system, the nature of a response of an individual fish to stimuli from its environment depends upon the inherited characteristics of its nervous system, on what it has learned from past experience, and on the nature of the stimuli. Compared with the variety of human responses, however, that of a fish is stereotyped, not subject to much modification by “thought” or learning, and investigators must guard against anthropomorphic interpretations of fish behaviour.
Fishes perceive the world around them by the usual senses of sight, smell, hearing, touch, and taste and by special lateral line water-current detectors. In the few fishes that generate electric fields, a process that might best be called electrolocation aids in perception. One or another of these senses often is emphasized at the expense of others, depending upon the fish’s other adaptations. In fishes with large eyes, the sense of smell may be reduced; others, with small eyes, hunt and feed primarily by smell (such as some eels).
Specialized behaviour is primarily concerned with the three most important activities in the fish’s life: feeding, reproduction, and escape from enemies. Schooling behaviour of sardines on the high seas, for instance, is largely a protective device to avoid enemies, but it is also associated with and modified by their breeding and feeding requirements. Predatory fishes are often solitary, lying in wait to dart suddenly after their prey, a kind of locomotion impossible for beaked parrot fishes, which feed on coral, swimming in small groups from one coral head to the next. In addition, some predatory fishes that inhabit pelagic environments, such as tunas, often school.
Sleep in fishes, all of which lack true eyelids, consists of a seemingly listless state in which the fish maintains its balance but moves slowly. If attacked or disturbed, most can dart away. A few kinds of fishes lie on the bottom to sleep. Most catfishes, some loaches, and some eels and electric fishes are strictly nocturnal, being active and hunting for food during the night and retiring during the day to holes, thick vegetation, or other protective parts of the environment.
Communication between members of a species or between members of two or more species often is extremely important, especially in breeding behaviour (see below Reproduction). The mode of communication may be visual, as between the small so-called cleaner fish and a large fish of a very different species. The larger fish often allows the cleaner to enter its mouth to remove gill parasites. The cleaner is recognized by its distinctive colour and actions and therefore is not eaten, even if the larger fish is normally a predator. Communication is often chemical, signals being sent by specific chemicals called pheromones.
Many fishes have a streamlined body and swim freely in open water. Fish locomotion is closely correlated with habitat and ecological niche (the general position of the animal to its environment).
Many fishes in both marine and fresh waters swim at the surface and have mouths adapted to feed best (and sometimes only) at the surface. Often such fishes are long and slender, able to dart at surface insects or at other surface fishes and in turn to dart away from predators; needlefishes, halfbeaks, and topminnows (such as killifish and mosquito fish) are good examples. Oceanic flying fishes escape their predators by gathering speed above the water surface, with the lower lobe of the tail providing thrust in the water. They then glide hundreds of yards on enlarged, winglike pectoral and pelvic fins. South American freshwater flying fishes escape their enemies by jumping and propelling their strongly keeled bodies out of the water.
So-called mid-water swimmers, the most common type of fish, are of many kinds and live in many habitats. The powerful fusiform tunas and the trouts, for example, are adapted for strong, fast swimming, the tunas to capture prey speedily in the open ocean and the trouts to cope with the swift currents of streams and rivers. The trout body form is well adapted to many habitats. Fishes that live in relatively quiet waters such as bays or lake shores or slow rivers usually are not strong, fast swimmers but are capable of short, quick bursts of speed to escape a predator. Many of these fishes have their sides flattened, examples being the sunfish and the freshwater angelfish of aquarists. Fish associated with the bottom or substrate usually are slow swimmers. Open-water plankton-feeding fishes almost always remain fusiform and are capable of rapid, strong movement (for example, sardines and herrings of the open ocean and also many small minnows of streams and lakes).
Bottom-living fishes are of many kinds and have undergone many types of modification of their body shape and swimming habits. Rays, which evolved from strong-swimming mid-water sharks, usually stay close to the bottom and move by undulating their large pectoral fins. Flounders live in a similar habitat and move over the bottom by undulating the entire body. Many bottom fishes dart from place to place, resting on the bottom between movements, a motion common in gobies. One goby relative, the mudskipper, has taken to living at the edge of pools along the shore of muddy mangrove swamps. It escapes its enemies by flipping rapidly over the mud, out of the water. Some catfishes, synbranchid eels, the so-called climbing perch, and a few other fishes venture out over damp ground to find more promising waters than those that they left. They move by wriggling their bodies, sometimes using strong pectoral fins; most have accessory air-breathing organs. Many bottom-dwelling fishes live in mud holes or rocky crevices. Marine eels and gobies commonly are found in such habitats and for the most part venture far beyond their cavelike homes. Some bottom dwellers, such as the clingfishes (Gobiesocidae), have developed powerful adhesive disks that enable them to remain in place on the substrate in areas such as rocky coasts, where the action of the waves is great.
The methods of reproduction in fishes are varied, but most fishes lay a large number of small eggs, fertilized and scattered outside of the body. The eggs of pelagic fishes usually remain suspended in the open water. Many shore and freshwater fishes lay eggs on the bottom or among plants. Some have adhesive eggs. The mortality of the young and especially of the eggs is very high, and often only a few individuals grow to maturity out of hundreds, thousands, and in some cases millions of eggs laid.
Males produce sperm, usually as a milky white substance called milt, in two (sometimes one) testes within the body cavity. In bony fishes a sperm duct leads from each testis to a urogenital opening behind the vent or anus. In sharks and rays and in cyclostomes the duct leads to a cloaca. Sometimes the pelvic fins are modified to help transmit the milt to the eggs at the female’s vent or on the substrate where the female has placed them. Sometimes accessory organs are used to fertilize females internally—for example, the claspers of many sharks and rays.
In the females the eggs are formed in two ovaries (sometimes only one) and pass through the ovaries to the urogenital opening and to the outside. In some fishes the eggs are fertilized internally but are shed before development takes place. Members of about a dozen families each of bony fishes (teleosts) and sharks bear live young. Many skates and rays also bear live young. In some bony fishes the eggs simply develop within the female, the young emerging when the eggs hatch (ovoviviparous). Others develop within the ovary and are nourished by ovarian tissues after hatching (viviparous). There are also other methods utilized by fishes to nourish young within the female. In all live-bearers the young are born at a relatively large size and are few in number. In one family of primarily marine fishes, the surfperches from the Pacific coast of North America, Japan, and Korea, the males of at least one species are born sexually mature, although they are not fully grown.
Some fishes are hermaphroditic—an individual producing both sperm and eggs, usually at different stages of its life. Self-fertilization, however, is probably rare.
Successful reproduction and, in many cases, defense of the eggs and the young are assured by rather stereotypical but often elaborate courtship and parental behaviour, either by the male or the female or both. Some fishes prepare nests by hollowing out depressions in the sand bottom (cichlids, for example), build nests with plant materials and sticky threads excreted by the kidneys (sticklebacks), or blow a cluster of mucus-covered bubbles at the water surface (gouramis). The eggs are laid in these structures. Some varieties of cichlids and catfishes incubate eggs in their mouths.
Some fishes, such as salmon, undergo long migrations from the ocean and up large rivers to spawn in the gravel beds where they themselves hatched (anadromous fishes). Some, such as the freshwater eels (family Anguillidae), live and grow to maturity in fresh water and migrate to the sea to spawn (catadromous fishes). Other fishes undertake shorter migrations from lakes into streams, within the ocean, or enter spawning habitats that they do not ordinarily occupy in other ways.
The basic structure and function of the fish body are similar to those of all other vertebrates. The usual four types of tissues are present: surface or epithelial, connective (bone, cartilage, and fibrous tissues, as well as their derivative, blood), nerve, and muscle tissues. In addition, the fish’s organs and organ systems parallel those of other vertebrates.
The typical fish body is streamlined and spindle-shaped, with an anterior head, a gill apparatus, and a heart, the latter lying in the midline just below the gill chamber. The body cavity, containing the vital organs, is situated behind the head in the lower anterior part of the body. The anus usually marks the posterior termination of the body cavity and most often occurs just in front of the base of the anal fin. The spinal cord and vertebral column continue from the posterior part of the head to the base of the tail fin, passing dorsal to the body cavity and through the caudal (tail) region behind the body cavity. Most of the body is of muscular tissue, a high proportion of which is necessitated by swimming. In the course of evolution this basic body plan has been modified repeatedly into the many varieties of fish shapes that exist today.
The skeleton forms an integral part of the fish’s locomotion system, as well as serving to protect vital parts. The internal skeleton consists of the skull bones (except for the roofing bones of the head, which are really part of the external skeleton), the vertebral column, and the fin supports (fin rays). The fin supports are derived from the external skeleton but will be treated here because of their close functional relationship to the internal skeleton. The internal skeleton of cyclostomes, sharks, and rays is of cartilage; that of many fossil groups and some primitive living fishes is mostly of cartilage but may include some bone. In place of the vertebral column, the earliest vertebrates had a fully developed notochord, a flexible stiff rod of viscous cells surrounded by a strong fibrous sheath. During the evolution of modern fishes the rod was replaced in part by cartilage and then by ossified cartilage. Sharks and rays retain a cartilaginous vertebral column; bony fishes have spool-shaped vertebrae that in the more primitive living forms only partially replace the notochord. The skull, including the gill arches and jaws of bony fishes, is fully, or at least partially, ossified. That of sharks and rays remains cartilaginous, at times partially replaced by calcium deposits but never by true bone.
The supportive elements of the fins (basal or radial bones or both) have changed greatly during fish evolution. Some of these changes are described in the section below (Evolution and paleontology). Most fishes possess a single dorsal fin on the midline of the back. Many have two and a few have three dorsal fins. The other fins are the single tail and anal fins and paired pelvic and pectoral fins. A small fin, the adipose fin, with hairlike fin rays, occurs in many of the relatively primitive teleosts (such as trout) on the back near the base of the caudal fin.
The skin of a fish must serve many functions. It aids in maintaining the osmotic balance, provides physical protection for the body, is the site of coloration, contains sensory receptors, and, in some fishes, functions in respiration. Mucous glands, which aid in maintaining the water balance and offer protection from bacteria, are extremely numerous in fish skin, especially in cyclostomes and teleosts. Since mucous glands are present in the modern lampreys, it is reasonable to assume that they were present in primitive fishes, such as the ancient Silurian and Devonian agnathans. Protection from abrasion and predation is another function of the fish skin, and dermal (skin) bone arose early in fish evolution in response to this need. It is thought that bone first evolved in skin and only later invaded the cartilaginous areas of the fish’s body, to provide additional support and protection. There is some argument as to which came first, cartilage or bone, and fossil evidence does not settle the question. In any event, dermal bone has played an important part in fish evolution and has different characteristics in different groups of fishes. Several groups are characterized at least in part by the kind of bony scales they possess.
Scales have played an important part in the evolution of fishes. Primitive fishes usually had thick bony plates or thick scales in several layers of bone, enamel, and related substances. Modern teleost fishes have scales of bone, which, while still protective, allow much more freedom of motion in the body. A few modern teleosts (some catfishes, sticklebacks, and others) have secondarily acquired bony plates in the skin. Modern and early sharks possessed placoid scales, a relatively primitive type of scale with a toothlike structure, consisting of an outside layer of enamel-like substance (vitrodentine), an inner layer of dentine, and a pulp cavity containing nerves and blood vessels. Primitive bony fishes had thick scales of either the ganoid or the cosmoid type. Cosmoid scales have a hard, enamel-like outer layer, an inner layer of cosmine (a form of dentine), and then a layer of vascular bone (isopedine). In ganoid scales the hard outer layer is different chemically and is called ganoin. Under this is a cosminelike layer and then a vascular bony layer. The thin, translucent bony scales of modern fishes, called cycloid and ctenoid (the latter distinguished by serrations at the edges), lack enameloid and dentine layers.
Skin has several other functions in fishes. It is well supplied with nerve endings and presumably receives tactile, thermal, and pain stimuli. Skin is also well supplied with blood vessels. Some fishes breathe in part through the skin, by the exchange of oxygen and carbon dioxide between the surrounding water and numerous small blood vessels near the skin surface.
Skin serves as protection through the control of coloration. Fishes exhibit an almost limitless range of colours. The colours often blend closely with the surroundings, effectively hiding the animal. Many fishes use bright colours for territorial advertisement or as recognition marks for other members of their own species, or sometimes for members of other species. Many fishes can change their colour to a greater or lesser degree, by movement of pigment within the pigment cells (chromatophores). Black pigment cells (melanophores), of almost universal occurrence in fishes, are often juxtaposed with other pigment cells. When placed beneath iridocytes or leucophores (bearing the silvery or white pigment guanine), melanophores produce structural colours of blue and green. These colours are often extremely intense, because they are formed by refraction of light through the needlelike crystals of guanine. The blue and green refracted colours are often relatively pure, lacking the red and yellow rays, which have been absorbed by the black pigment (melanin) of the melanophores. Yellow, orange, and red colours are produced by erythrophores, cells containing the appropriate carotenoid pigments. Other colours are produced by combinations of melanophores, erythrophores, and iridocytes.
The major portion of the body of most fishes consists of muscles. Most of the mass is trunk musculature, the fin muscles usually being relatively small. The caudal fin is usually the most powerful fin, being moved by the trunk musculature. The body musculature is usually arranged in rows of chevron-shaped segments on each side. Contractions of these segments, each attached to adjacent vertebrae and vertebral processes, bends the body on the vertebral joint, producing successive undulations of the body, passing from the head to the tail, and producing driving strokes of the tail. It is the latter that provides the strong forward movement for most fishes.
The digestive system, in a functional sense, starts at the mouth, with the teeth used to capture prey or collect plant foods. Mouth shape and tooth structure vary greatly in fishes, depending on the kind of food normally eaten. Most fishes are predacious, feeding on small invertebrates or other fishes and have simple conical teeth on the jaws, on at least some of the bones of the roof of the mouth, and on special gill arch structures just in front of the esophagus. The latter are throat teeth. Most predacious fishes swallow their prey whole, and the teeth are used for grasping and holding prey, for orienting prey to be swallowed (head first) and for working the prey toward the esophagus. There are a variety of tooth types in fishes. Some fishes, such as sharks and piranhas, have cutting teeth for biting chunks out of their victims. A shark’s tooth, although superficially like that of a piranha, appears in many respects to be a modified scale, while that of the piranha is like that of other bony fishes, consisting of dentine and enamel. Parrot fishes have beaklike mouths with short incisor-like teeth for breaking off coral and have heavy pavementlike throat teeth for crushing the coral. Some catfishes have small brushlike teeth, arranged in rows on the jaws, for scraping plant and animal growth from rocks. Many fishes (such as the Cyprinidae or minnows) have no jaw teeth at all but have very strong throat teeth.
Some fishes gather planktonic food by straining it from their gill cavities with numerous elongate stiff rods (gill rakers) anchored by one end to the gill bars. The food collected on these rods is passed to the throat, where it is swallowed. Most fishes have only short gill rakers that help keep food particles from escaping out the mouth cavity into the gill chamber.
Once reaching the throat, food enters a short, often greatly distensible esophagus, a simple tube with a muscular wall leading into a stomach. The stomach varies greatly in fishes, depending upon the diet. In most predacious fishes it is a simple straight or curved tube or pouch with a muscular wall and a glandular lining. Food is largely digested there and leaves the stomach in liquid form.
Between the stomach and the intestine, ducts enter the digestive tube from the liver and pancreas. The liver is a large, clearly defined organ. The pancreas may be embedded in it, diffused through it, or broken into small parts spread along some of the intestine. The junction between the stomach and the intestine is marked by a muscular valve. Pyloric ceca (blind sacs) occur in some fishes at this junction and have a digestive or absorptive function or both.
The intestine itself is quite variable in length, depending upon the fish’s diet. It is short in predacious forms, sometimes no longer than the body cavity, but long in herbivorous forms, being coiled and several times longer than the entire length of the fish in some species of South American catfishes. The intestine is primarily an organ for absorbing nutrients into the bloodstream. The larger its internal surface, the greater its absorptive efficiency, and a spiral valve is one method of increasing its absorption surface.
Sharks, rays, chimaeras, lungfishes, surviving chondrosteans, holosteans, and even a few of the more primitive teleosts have a spiral valve or at least traces of it in the intestine. Most modern teleosts have increased the area of the intestinal walls by having numerous folds and villi (fingerlike projections) somewhat like those in humans. Undigested substances are passed to the exterior through the anus in most teleost fishes. In lungfishes, sharks, and rays, it is first passed through the cloaca, a common cavity receiving the intestinal opening and the ducts from the urogenital system.
Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Water taken in continuously through the mouth passes backward between the gill bars and over the gill filaments, where the exchange of gases takes place. The gills are protected by a gill cover in teleosts and many other fishes but by flaps of skin in sharks, rays, and some of the older fossil fish groups. The blood capillaries in the gill filaments are close to the gill surface to take up oxygen from the water and to give up excess carbon dioxide to the water.
Most modern fishes have a hydrostatic (ballast) organ, called the swim bladder, that lies in the body cavity just below the kidney and above the stomach and intestine. It originated as a diverticulum of the digestive canal. In advanced teleosts, especially the acanthopterygians, the bladder has lost its connection with the digestive tract, a condition called physoclistic. The connection has been retained (physostomous) by many relatively primitive teleosts. In several unrelated lines of fishes, the bladder has become specialized as a lung or, at least, as a highly vascularized accessory breathing organ. Some fishes with such accessory organs are obligate air breathers and will drown if denied access to the surface, even in well-oxygenated water. Fishes with a hydrostatic form of swim bladder can control their depth by regulating the amount of gas in the bladder. The gas, mostly oxygen, is secreted into the bladder by special glands, rendering the fish more buoyant; the gas is absorbed into the bloodstream by another special organ, reducing the overall buoyancy and allowing the fish to sink. Some deep-sea fishes may have oils, rather than gas, in the bladder. Other deep-sea and some bottom-living forms have much-reduced swim bladders or have lost the organ entirely.
The swim bladder of fishes follows the same developmental pattern as the lungs of land vertebrates. There is no doubt that the two structures have the same historical origin in primitive fishes. More or less intermediate forms still survive among the more primitive types of fishes, such as the lungfishes Lepidosiren and Protopterus.
The circulatory, or blood vascular, system consists of the heart, the arteries, the capillaries, and the veins. It is in the capillaries that the interchange of oxygen, carbon dioxide, nutrients, and other substances such as hormones and waste products takes place. The capillaries lead to the veins, which return the venous blood with its waste products to the heart, kidneys, and gills. There are two kinds of capillary beds: those in the gills and those in the rest of the body. The heart, a folded continuous muscular tube with three or four saclike enlargements, undergoes rhythmic contractions and receives venous blood in a sinus venosus. It passes the blood to an auricle and then into a thick muscular pump, the ventricle. From the ventricle the blood goes to a bulbous structure at the base of a ventral aorta just below the gills. The blood passes to the afferent (receiving) arteries of the gill arches and then to the gill capillaries. There waste gases are given off to the environment, and oxygen is absorbed. The oxygenated blood enters efferent (exuant) arteries of the gill arches and then flows into the dorsal aorta. From there blood is distributed to the tissues and organs of the body. One-way valves prevent backflow. The circulation of fishes thus differs from that of the reptiles, birds, and mammals in that oxygenated blood is not returned to the heart prior to distribution to the other parts of the body.
The primary excretory organ in fishes, as in other vertebrates, is the kidney. In fishes some excretion also takes place in the digestive tract, skin, and especially the gills (where ammonia is given off). Compared with land vertebrates, fishes have a special problem in maintaining their internal environment at a constant concentration of water and dissolved substances, such as salts. Proper balance of the internal environment (homeostasis) of a fish is in a great part maintained by the excretory system, especially the kidney.
The kidney, gills, and skin play an important role in maintaining a fish’s internal environment and checking the effects of osmosis. Marine fishes live in an environment in which the water around them has a greater concentration of salts than they can have inside their body and still maintain life. Freshwater fishes, on the other hand, live in water with a much lower concentration of salts than they require inside their bodies. Osmosis tends to promote the loss of water from the body of a marine fish and absorption of water by that of a freshwater fish. Mucus in the skin tends to slow the process but is not a sufficient barrier to prevent the movement of fluids through the permeable skin. When solutions on two sides of a permeable membrane have different concentrations of dissolved substances, water will pass through the membrane into the more concentrated solution, while the dissolved chemicals move into the area of lower concentration (diffusion).
The kidney of freshwater fishes is often larger in relation to body weight than that of marine fishes. In both groups the kidney excretes wastes from the body, but the kidney of freshwater fishes also excretes large amounts of water, counteracting the water absorbed through the skin. Freshwater fishes tend to lose salt to the environment and must replace it. They get some salt from their food, but the gills and skin inside the mouth actively absorb salt from water passed through the mouth. This absorption is performed by special cells capable of moving salts against the diffusion gradient. Freshwater fishes drink very little water and take in little water with their food.
Marine fishes must conserve water, and therefore their kidneys excrete little water. To maintain their water balance, marine fishes drink large quantities of seawater, retaining most of the water and excreting the salt. Most nitrogenous waste in marine fishes appears to be secreted by the gills as ammonia. Marine fishes can excrete salt by clusters of special cells (chloride cells) in the gills.
There are several teleosts—for example, the salmon—that travel between fresh water and seawater and must adjust to the reversal of osmotic gradients. They adjust their physiological processes by spending time (often surprisingly little time) in the intermediate brackish environment.
Marine hagfishes, sharks, and rays have osmotic concentrations in their blood about equal to that of seawater and so do not have to drink water nor perform much physiological work to maintain their osmotic balance. In sharks and rays the osmotic concentration is kept high by retention of urea in the blood. Freshwater sharks have a lowered concentration of urea in the blood.
Endocrine glands secrete their products into the bloodstream and body tissues and, along with the central nervous system, control and regulate many kinds of body functions. Cyclostomes have a well-developed endocrine system, and presumably it was well developed in the early Agnatha, ancestral to modern fishes. Although the endocrine system in fishes is similar to that of higher vertebrates, there are numerous differences in detail. The pituitary, the thyroid, the suprarenals, the adrenals, the pancreatic islets, the sex glands (ovaries and testes), the inner wall of the intestine, and the bodies of the ultimobranchial gland make up the endocrine system in fishes. There are some others whose function is not well understood. These organs regulate sexual activity and reproduction, growth, osmotic pressure, general metabolic activities such as the storage of fat and the utilization of foodstuffs, blood pressure, and certain aspects of skin colour. Many of these activities are also controlled in part by the central nervous system, which works with the endocrine system in maintaining the life of a fish. Some parts of the endocrine system are developmentally, and undoubtedly evolutionarily, derived from the nervous system.
As in all vertebrates, the nervous system of fishes is the primary mechanism coordinating body activities, as well as integrating these activities in the appropriate manner with stimuli from the environment. The central nervous system, consisting of the brain and spinal cord, is the primary integrating mechanism. The peripheral nervous system, consisting of nerves that connect the brain and spinal cord to various body organs, carries sensory information from special receptor organs such as the eyes, internal ears, nares (sense of smell), taste glands, and others to the integrating centres of the brain and spinal cord. The peripheral nervous system also carries information via different nerve cells from the integrating centres of the brain and spinal cord. This coded information is carried to the various organs and body systems, such as the skeletal muscular system, for appropriate action in response to the original external or internal stimulus. Another branch of the nervous system, the autonomic nervous system, helps to coordinate the activities of many glands and organs and is itself closely connected to the integrating centres of the brain.
The brain of the fish is divided into several anatomical and functional parts, all closely interconnected but each serving as the primary centre of integrating particular kinds of responses and activities. Several of these centres or parts are primarily associated with one type of sensory perception, such as sight, hearing, or smell (olfaction).
The sense of smell is important in almost all fishes. Certain eels with tiny eyes depend mostly on smell for location of food. The olfactory, or nasal, organ of fishes is located on the dorsal surface of the snout. The lining of the nasal organ has special sensory cells that perceive chemicals dissolved in the water, such as substances from food material, and send sensory information to the brain by way of the first cranial nerve. Odour also serves as an alarm system. Many fishes, especially various species of freshwater minnows, react with alarm to a chemical released from the skin of an injured member of their own species.
Many fishes have a well-developed sense of taste, and tiny pitlike taste buds or organs are located not only within their mouth cavities but also over their heads and parts of their body. Catfishes, which often have poor vision, have barbels (“whiskers”) that serve as supplementary taste organs, those around the mouth being actively used to search out food on the bottom. Some species of naturally blind cave fishes are especially well supplied with taste buds, which often cover most of their body surface.
Sight is extremely important in most fishes. The eye of a fish is basically like that of all other vertebrates, but the eyes of fishes are extremely varied in structure and adaptation. In general, fishes living in dark and dim water habitats have large eyes, unless they have specialized in some compensatory way so that another sense (such as smell) is dominant, in which case the eyes will often be reduced. Fishes living in brightly lighted shallow waters often will have relatively small but efficient eyes. Cyclostomes have somewhat less elaborate eyes than other fishes, with skin stretched over the eyeball perhaps making their vision somewhat less effective. Most fishes have a spherical lens and accommodate their vision to far or near subjects by moving the lens within the eyeball. A few sharks accommodate by changing the shape of the lens, as in land vertebrates. Those fishes that are heavily dependent upon the eyes have especially strong muscles for accommodation. Most fishes see well, despite the restrictions imposed by frequent turbidity of the water and by light refraction.
Fossil evidence suggests that colour vision evolved in fishes more than 300 million years ago, but not all living fishes have retained this ability. Experimental evidence indicates that many shallow-water fishes, if not all, have colour vision and see some colours especially well, but some bottom-dwelling shore fishes live in areas where the water is sufficiently deep to filter out most if not all colours, and these fishes apparently never see colours. When tested in shallow water, they apparently are unable to respond to colour differences.
Sound perception and balance are intimately associated senses in a fish. The organs of hearing are entirely internal, located within the skull, on each side of the brain and somewhat behind the eyes. Sound waves, especially those of low frequencies, travel readily through water and impinge directly upon the bones and fluids of the head and body, to be transmitted to the hearing organs. Fishes readily respond to sound; for example, a trout conditioned to escape by the approach of fishermen will take flight upon perceiving footsteps on a stream bank even if it cannot see a fisherman. Compared with humans, however, the range of sound frequencies heard by fishes is greatly restricted. Many fishes communicate with each other by producing sounds in their swim bladders, in their throats by rasping their teeth, and in other ways.
A fish or other vertebrate seldom has to rely on a single type of sensory information to determine the nature of the environment around it. A catfish uses taste and touch when examining a food object with its oral barbels. Like most other animals, fishes have many touch receptors over their body surface. Pain and temperature receptors also are present in fishes and presumably produce the same kind of information to a fish as to humans. Fishes react in a negative fashion to stimuli that would be painful to human beings, suggesting that they feel a sensation of pain.
An important sensory system in fishes that is absent in other vertebrates (except some amphibians) is the lateral line system. This consists of a series of heavily innervated small canals located in the skin and bone around the eyes, along the lower jaw, over the head, and down the mid-side of the body, where it is associated with the scales. Intermittently along these canals are located tiny sensory organs (pit organs) that apparently detect changes in pressure. The system allows a fish to sense changes in water currents and pressure, thereby helping the fish to orient itself to the various changes that occur in the physical environment.

The Space Shuttle program, operated by NASA from 1981 to 2011, was a groundbreaking human spaceflight program that utilized various components, including the Space Shuttle Orbiter, the Space Shuttle External Tank (ET), and the Solid Rocket Boosters (SRBs). In this response, we will focus on the Space Shuttle External Tank and Booster Rockets, discussing their design, purpose, and key aspects. Please note that the following information is based on the program up until 2000, as specified in your request.
Space Shuttle External Tank (ET):
The Space Shuttle External Tank played a crucial role in the Space Shuttle launch system. It was the largest component of the Space Shuttle stack and provided the primary propellant for the Orbiter's main engines. Here are some key points about the External Tank:
Design and Structure:
The External Tank had a cylindrical shape and consisted of three major components: the forward liquid oxygen (LOX) tank, the aft liquid hydrogen (LH2) tank, and a connecting intertank structure.
The LOX tank, located at the forward end, contained approximately 1.4 million liters (380,000 gallons) of liquid oxygen.
The LH2 tank, positioned at the aft end, held around 1.9 million liters (526,000 gallons) of liquid hydrogen.
The intertank structure connected the LOX and LH2 tanks and housed various components, including avionics, electrical wiring, and feedlines.
The tanks were constructed using lightweight materials, such as aluminum alloys, to reduce the overall weight of the External Tank.
Function:
The primary function of the External Tank was to supply propellant to the Space Shuttle's three main engines.
The LOX and LH2 stored in the External Tank were funneled through feedlines and supplied to the Orbiter's engines at an optimal mix ratio for combustion.
As the propellant was consumed, the tank's structure progressively lightened, reducing its mass and enabling more efficient ascent to orbit.
Unlike the Solid Rocket Boosters, the External Tank was not reusable and was jettisoned after its propellant was depleted.
Thermal Protection:
The External Tank experienced extreme temperature variations during launch and reentry, requiring robust thermal protection measures.
The LOX tank was covered with sprayed-on foam insulation to prevent excessive heat absorption from the environment and maintain the propellant's low temperature.
The LH2 tank, due to its extremely low temperature, did not require extensive insulation but instead relied on a combination of passive and active cooling techniques.
Solid Rocket Boosters (SRBs):
The Space Shuttle Solid Rocket Boosters were two large, reusable rocket motors attached to the sides of the External Tank. Here's some information about the SRBs:
Design and Structure:
Each Solid Rocket Booster was approximately 45 meters (149 feet) long and 3.7 meters (12.2 feet) in diameter.
The boosters were composed of several cylindrical segments, including the forward skirt, motor segments, aft skirt, and nozzle.
The motor segments contained solid propellant, which provided the necessary thrust during the Shuttle's initial ascent phase.
The nozzles at the aft end directed the exhaust gases generated by the propellant combustion.
Function:
The Solid Rocket Boosters were responsible for providing the majority of the thrust required for the Space Shuttle to break free from Earth's gravity.
They ignited prior to liftoff and remained active for approximately two minutes, during which they consumed their solid propellant.
The boosters worked in conjunction with the Orbiter's main engines to propel the entire Space Shuttle stack off the launch pad and into space.
Following burnout, the SRBs were jettisoned and subsequently recovered from the ocean, refurbished, and prepared for future missions.
Parachute Recovery:
After separation, the SRBs were equipped with parachutes to facilitate their controlled descent and landing in the ocean.
A combination of drogue chutes and main parachutes slowed the descent and ensured a gentle impact with the water.
Recovery ships positioned in the retrieval area would retrieve the boosters, tow them back to land, and prepare them for refurbishment and reuse.
Reusability and Refurbishment:
The Solid Rocket Boosters were designed to be reusable, offering cost savings for the Space Shuttle program.
After recovery, the boosters underwent an extensive refurbishment process, including disassembly, cleaning, inspection, replacement of worn or damaged components, and propellant reload.
This refurbishment process allowed each SRB to be flown multiple times, reducing overall launch costs.
In summary, the Space Shuttle External Tank and Solid Rocket Boosters were integral components of the Space Shuttle system. The External Tank provided the necessary propellants for the Orbiter's main engines, while the Solid Rocket Boosters generated the majority of the thrust during the initial ascent phase. The External Tank was not reusable and was jettisoned after use, while the SRBs were recovered, refurbished, and reused for subsequent missions. These components worked together to propel the Space Shuttle into orbit, advancing human space exploration and scientific endeavors.
The John F. Kennedy Space Center (KSC, originally known as the NASA Launch Operations Center), located on Merritt Island, Florida, is one of the National Aeronautics and Space Administration's (NASA) ten field centers. Since December 1968, KSC has been NASA's primary launch center of American spaceflight, research, and technology. Launch operations for the Apollo, Skylab and Space Shuttle programs were carried out from Kennedy Space Center Launch Complex 39 and managed by KSC. Located on the east coast of Florida, KSC is adjacent to Cape Canaveral Space Force Station (CCSFS). The management of the two entities work very closely together, share resources and operate facilities on each other's property.
Though the first Apollo flights and all Project Mercury and Project Gemini flights took off from the then-Cape Canaveral Air Force Station, the launches were managed by KSC and its previous organization, the Launch Operations Directorate. Starting with the fourth Gemini mission, the NASA launch control center in Florida (Mercury Control Center, later the Launch Control Center) began handing off control of the vehicle to the Mission Control Center in Houston, shortly after liftoff; in prior missions it held control throughout the entire mission.
Additionally, the center manages launch of robotic and commercial crew missions and researches food production and in-situ resource utilization for off-Earth exploration. Since 2010, the center has worked to become a multi-user spaceport through industry partnerships, even adding a new launch pad (LC-39C) in 2015.
There are about 700 facilities and buildings grouped throughout the center's 144,000 acres (580 km2). Among the unique facilities at KSC are the 525-foot (160 m) tall Vehicle Assembly Building for stacking NASA's largest rockets, the Launch Control Center, which conducts space launches at KSC, the Operations and Checkout Building, which houses the astronauts dormitories and suit-up area, a Space Station factory, and a 3-mile (4.8 km) long Shuttle Landing Facility. There is also a Visitor Complex on site that is open to the public.
Since 1949, the military had been performing launch operations at what would become Cape Canaveral Space Force Station. In December 1959, the Department of Defense transferred 5,000 personnel and the Missile Firing Laboratory to NASA to become the Launch Operations Directorate under NASA's Marshall Space Flight Center.
President John F. Kennedy's 1961 goal of a crewed lunar landing by 1970 required an expansion of launch operations. On July 1, 1962, the Launch Operations Directorate was separated from MSFC to become the Launch Operations Center (LOC). Also, Cape Canaveral was inadequate to host the new launch facility design required for the mammoth 363-foot (111 m) tall, 7,500,000-pound-force (33,000 kN) thrust Saturn V rocket, which would be assembled vertically in a large hangar and transported on a mobile platform to one of several launch pads. Therefore, the decision was made to build a new LOC site located adjacent to Cape Canaveral on Merritt Island.
NASA began land acquisition in 1962, buying title to 131 square miles (340 km2) and negotiating with the state of Florida for an additional 87 square miles (230 km2). The major buildings in KSC's Industrial Area were designed by architect Charles Luckman. Construction began in November 1962, and Kennedy visited the site twice in 1962, and again just a week before his assassination on November 22, 1963.
On November 29, 1963, the facility was named by President Lyndon B. Johnson under Executive Order 11129. Johnson's order joined both the civilian LOC and the military Cape Canaveral station ("the facilities of Station No. 1 of the Atlantic Missile Range") under the designation "John F. Kennedy Space Center", spawning some confusion joining the two in the public mind. NASA Administrator James E. Webb clarified this by issuing a directive stating the Kennedy Space Center name applied only to the LOC, while the Air Force issued a general order renaming the military launch site Cape Kennedy Air Force Station.
Located on Merritt Island, Florida, the center is north-northwest of Cape Canaveral on the Atlantic Ocean, midway between Miami and Jacksonville on Florida's Space Coast, due east of Orlando. It is 34 miles (55 km) long and roughly six miles (9.7 km) wide, covering 219 square miles (570 km2). KSC is a major central Florida tourist destination and is approximately one hour's drive from the Orlando area. The Kennedy Space Center Visitor Complex offers public tours of the center and Cape Canaveral Space Force Station.
From 1967 through 1973, there were 13 Saturn V launches, including the ten remaining Apollo missions after Apollo 7. The first of two uncrewed flights, Apollo 4 (Apollo-Saturn 501) on November 9, 1967, was also the first rocket launch from KSC. The Saturn V's first crewed launch on December 21, 1968, was Apollo 8's lunar orbiting mission. The next two missions tested the Lunar Module: Apollo 9 (Earth orbit) and Apollo 10 (lunar orbit). Apollo 11, launched from Pad A on July 16, 1969, made the first Moon landing on July 20. The Apollo 11 launch included crewmembers Neil Armstrong, Michael Collins, and Buzz Aldrin, and attracted a record-breaking 650 million television viewers. Apollo 12 followed four months later. From 1970 to 1972, the Apollo program concluded at KSC with the launches of missions 13 through 17.
On May 14, 1973, the last Saturn V launch put the Skylab space station in orbit from Pad 39A. By this time, the Cape Kennedy pads 34 and 37 used for the Saturn IB were decommissioned, so Pad 39B was modified to accommodate the Saturn IB, and used to launch three crewed missions to Skylab that year, as well as the final Apollo spacecraft for the Apollo–Soyuz Test Project in 1975.
As the Space Shuttle was being designed, NASA received proposals for building alternative launch-and-landing sites at locations other than KSC, which demanded study. KSC had important advantages, including its existing facilities; location on the Intracoastal Waterway; and its southern latitude, which gives a velocity advantage to missions launched in easterly near-equatorial orbits. Disadvantages included: its inability to safely launch military missions into polar orbit, since spent boosters would be likely to fall on the Carolinas or Cuba; corrosion from the salt air; and frequent cloudy or stormy weather. Although building a new site at White Sands Missile Range in New Mexico was seriously considered, NASA announced its decision in April 1972 to use KSC for the shuttle. Since the Shuttle could not be landed automatically or by remote control, the launch of Columbia on April 12, 1981 for its first orbital mission STS-1, was NASA's first crewed launch of a vehicle that had not been tested in prior uncrewed launches.
In 1976, the VAB's south parking area was the site of Third Century America, a science and technology display commemorating the U.S. Bicentennial. Concurrent with this event, the U.S. flag was painted on the south side of the VAB. During the late 1970s, LC-39 was reconfigured to support the Space Shuttle. Two Orbiter Processing Facilities were built near the VAB as hangars with a third added in the 1980s.
KSC's 2.9-mile (4.7 km) Shuttle Landing Facility (SLF) was the orbiters' primary end-of-mission landing site, although the first KSC landing did not take place until the tenth flight, when Challenger completed STS-41-B on February 11, 1984; the primary landing site until then was Edwards Air Force Base in California, subsequently used as a backup landing site. The SLF also provided a return-to-launch-site (RTLS) abort option, which was not utilized. The SLF is among the longest runways in the world.
On October 28, 2009, the Ares I-X launch from Pad 39B was the first uncrewed launch from KSC since the Skylab workshop in 1973.
Beginning in 1958, NASA and military worked side by side on robotic mission launches (previously referred to as unmanned), cooperating as they broke ground in the field. In the early 1960s, NASA had as many as two robotic mission launches a month. The frequent number of flights allowed for quick evolution of the vehicles, as engineers gathered data, learned from anomalies and implemented upgrades. In 1963, with the intent of KSC ELV work focusing on the ground support equipment and facilities, a separate Atlas/Centaur organization was formed under NASA's Lewis Center (now Glenn Research Center (GRC)), taking that responsibility from the Launch Operations Center (aka KSC).
Though almost all robotics missions launched from the Cape Canaveral Space Force Station (CCSFS), KSC "oversaw the final assembly and testing of rockets as they arrived at the Cape." In 1965, KSC's Unmanned Launch Operations directorate became responsible for all NASA uncrewed launch operations, including those at Vandenberg Space Force Base. From the 1950s to 1978, KSC chose the rocket and payload processing facilities for all robotic missions launching in the U.S., overseeing their near launch processing and checkout. In addition to government missions, KSC performed this service for commercial and foreign missions also, though non-U.S. government entities provided reimbursement. NASA also funded Cape Canaveral Space Force Station launch pad maintenance and launch vehicle improvements.
All this changed with the Commercial Space Launch Act of 1984, after which NASA only coordinated its own and National Oceanic and Atmospheric Administration (NOAA) ELV launches. Companies were able to "operate their own launch vehicles" and utilize NASA's launch facilities. Payload processing handled by private firms also started to occur outside of KSC. Reagan's 1988 space policy furthered the movement of this work from KSC to commercial companies. That same year, launch complexes on Cape Canaveral Air Force Force Station started transferring from NASA to Air Force Space Command management.
In the 1990s, though KSC was not performing the hands-on ELV work, engineers still maintained an understanding of ELVs and had contracts allowing them insight into the vehicles so they could provide knowledgeable oversight. KSC also worked on ELV research and analysis and the contractors were able to utilize KSC personnel as a resource for technical issues. KSC, with the payload and launch vehicle industries, developed advances in automation of the ELV launch and ground operations to enable competitiveness of U.S. rockets against the global market.
In 1998, the Launch Services Program (LSP) formed at KSC, pulling together programs (and personnel) that already existed at KSC, GRC, Goddard Space Flight Center, and more to manage the launch of NASA and NOAA robotic missions. Cape Canaveral Space Force Station and VAFB are the primary launch sites for LSP missions, though other sites are occasionally used. LSP payloads such as the Mars Science Laboratory have been processed at KSC before being transferred to a launch pad on Cape Canaveral Space Force Station.
On 16 November 2022, at 06:47:44 UTC the Space Launch System (SLS) was launched from Complex 39B as part of the Artemis 1 mission.
As the International Space Station modules design began in the early 1990s, KSC began to work with other NASA centers and international partners to prepare for processing before launch onboard the Space Shuttles. KSC utilized its hands-on experience processing the 22 Spacelab missions in the Operations and Checkout Building to gather expectations of ISS processing. These experiences were incorporated into the design of the Space Station Processing Facility (SSPF), which began construction in 1991. The Space Station Directorate formed in 1996. KSC personnel were embedded at station module factories for insight into their processes.
From 1997 to 2007, KSC planned and performed on the ground integration tests and checkouts of station modules: three Multi-Element Integration Testing (MEIT) sessions and the Integration Systems Test (IST). Numerous issues were found and corrected that would have been difficult to nearly impossible to do on-orbit.
Today KSC continues to process ISS payloads from across the world before launch along with developing its experiments for on orbit. The proposed Lunar Gateway would be manufactured and processed at the Space Station Processing Facility.

Camp KSC: educational camps for schoolchildren in spring and summer, with a focus on space, aviation and robotics.
The KSC Industrial Area, where many of the center's support facilities are located, is 5 miles (8 km) south of LC-39. It includes the Headquarters Building, the Operations and Checkout Building and the Central Instrumentation Facility. The astronaut crew quarters are in the O&C; before it was completed, the astronaut crew quarters were located in Hangar S at the Cape Canaveral Missile Test Annex (now Cape Canaveral Space Force Station). Located at KSC was the Merritt Island Spaceflight Tracking and Data Network station (MILA), a key radio communications and spacecraft tracking complex.
Facilities at the Kennedy Space Center are directly related to its mission to launch and recover missions. Facilities are available to prepare and maintain spacecraft and payloads for flight. The Headquarters (HQ) Building houses offices for the Center Director, library, film and photo archives, a print shop and security. When the KSC Library first opened, it was part of the Army Ballistic Missile Agency. However, in 1965, the library moved into three separate sections in the newly opened NASA headquarters before eventually becoming a single unit in 1970. The library contains over four million items related to the history and the work at Kennedy. As one of ten NASA center libraries in the country, their collection focuses on engineering, science, and technology. The archives contain planning documents, film reels, and original photographs covering the history of KSC. The library is not open to the public but is available for KSC, Space Force, and Navy employees who work on site. Many of the media items from the collection are digitized and available through NASA's KSC Media Gallery Archived December 6, 2020, at the Wayback Machine or through their more up-to-date Flickr gallery.
A new Headquarters Building was completed in 2019 as part of the Central Campus consolidation. Groundbreaking began in 2014.
The center operated its own 17-mile (27 km) short-line railroad. This operation was discontinued in 2015, with the sale of its final two locomotives. A third had already been donated to a museum. The line was costing $1.3 million annually to maintain.
The Neil Armstrong Operations and Checkout Building (O&C) (previously known as the Manned Spacecraft Operations Building) is a historic site on the U.S. National Register of Historic Places dating back to the 1960s and was used to receive, process, and integrate payloads for the Gemini and Apollo programs, the Skylab program in the 1970s, and for initial segments of the International Space Station through the 1990s. The Apollo and Space Shuttle astronauts would board the astronaut transfer van to launch complex 39 from the O&C building.
The three-story, 457,000-square-foot (42,500 m2) Space Station Processing Facility (SSPF) consists of two enormous processing bays, an airlock, operational control rooms, laboratories, logistics areas and office space for support of non-hazardous Space Station and Shuttle payloads to ISO 14644-1 class 5 standards. Opened in 1994, it is the largest factory building in the KSC industrial area.
The Vertical Processing Facility (VPF) features a 71-by-38-foot (22 by 12 m) door where payloads that are processed in the vertical position are brought in and manipulated with two overhead cranes and a hoist capable of lifting up to 35 short tons (32 t).
The Hypergolic Maintenance and Checkout Area (HMCA) comprises three buildings that are isolated from the rest of the industrial area because of the hazardous materials handled there. Hypergolic-fueled modules that made up the Space Shuttle Orbiter's reaction control system, orbital maneuvering system and auxiliary power units were stored and serviced in the HMCF.
The Multi-Payload Processing Facility is a 19,647 square feet (1,825.3 m2) building used for Orion spacecraft and payload processing.
The Payload Hazardous Servicing Facility (PHSF) contains a 70-by-110-foot (21 by 34 m) service bay, with a 100,000-pound (45,000 kg), 85-foot (26 m) hook height. It also contains a 58-by-80-foot (18 by 24 m) payload airlock. Its temperature is maintained at 70 °F (21 °C).[55]
The Blue Origin rocket manufacturing facility is located immediately south of the KSC visitor complex. Completed in 2019, it serves as the company's factory for the manufacture of New Glenn orbital rockets.
Launch Complex 39 (LC-39) was originally built for the Saturn V, the largest and most powerful operational launch vehicle until the Space Launch System, for the Apollo crewed Moon landing program. Since the end of the Apollo program in 1972, LC-39 has been used to launch every NASA human space flight, including Skylab (1973), the Apollo–Soyuz Test Project (1975), and the Space Shuttle program (1981–2011).
Since December 1968, all launch operations have been conducted from launch pads A and B at LC-39. Both pads are on the ocean, 3 miles (4.8 km) east of the VAB. From 1969 to 1972, LC-39 was the "Moonport" for all six Apollo crewed Moon landing missions using the Saturn V, and was used from 1981 to 2011 for all Space Shuttle launches.
Human missions to the Moon required the large three-stage Saturn V rocket, which was 363 feet (111 meters) tall and 33 feet (10 meters) in diameter. At KSC, Launch Complex 39 was built on Merritt Island to accommodate the new rocket. Construction of the $800 million project began in November 1962. LC-39 pads A and B were completed by October 1965 (planned Pads C, D and E were canceled), the VAB was completed in June 1965, and the infrastructure by late 1966.
The complex includes: the Vehicle Assembly Building (VAB), a 130,000,000 cubic feet (3,700,000 m3) hangar capable of holding four Saturn Vs. The VAB was the largest structure in the world by volume when completed in 1965.
a transporter capable of carrying 5,440 tons along a crawlerway to either of two launch pads;
a 446-foot (136 m) mobile service structure, with three Mobile Launcher Platforms, each containing a fixed launch umbilical tower;
the Launch Control Center; and
a news media facility.
Launch Complex 48 (LC-48) is a multi-user launch site under construction for small launchers and spacecraft. It will be located between Launch Complex 39A and Space Launch Complex 41, with LC-39A to the north and SLC-41 to the south. LC-48 will be constructed as a "clean pad" to support multiple launch systems with differing propellant needs. While initially only planned to have a single pad, the complex is capable of being expanded to two at a later date.
As a part of promoting commercial space industry growth in the area and the overall center as a multi-user spaceport, KSC leases some of its properties. Here are some major examples:
Exploration Park to multiple users (partnership with Space Florida)
Shuttle Landing Facility to Space Florida (who contracts use to private companies)
Orbiter Processing Facility (OPF)-3 to Boeing (for CST-100 Starliner)
Launch Complex 39A, Launch Control Center Firing Room 4 and land for SpaceX's Roberts Road facility (Hanger X) to SpaceX
O&C High Bay to Lockheed Martin (for Orion processing)
Land for FPL's Space Coast Next Generation Solar Energy Center to Florida Power and Light (FPL)
Hypergolic Maintenance Facility (HMF) to United Paradyne Corporation (UPC)
The Kennedy Space Center Visitor Complex, operated by Delaware North since 1995, has a variety of exhibits, artifacts, displays and attractions on the history and future of human and robotic spaceflight. Bus tours of KSC originate from here. The complex also includes the separate Apollo/Saturn V Center, north of the VAB and the United States Astronaut Hall of Fame, six miles west near Titusville. There were 1.5 million visitors in 2009. It had some 700 employees.
It was announced on May 29, 2015, that the Astronaut Hall of Fame exhibit would be moved from its current location to another location within the Visitor Complex to make room for an upcoming high-tech attraction entitled "Heroes and Legends". The attraction, designed by Orlando-based design firm Falcon's Treehouse, opened November 11, 2016.
In March 2016, the visitor center unveiled the new location of the iconic countdown clock at the complex's entrance; previously, the clock was located with a flagpole at the press site. The clock was originally built and installed in 1969 and listed with the flagpole in the National Register of Historic Places in January 2000. In 2019, NASA celebrated the 50th anniversary of the Apollo program, and the launch of Apollo 10 on May 18. In summer of 2019, Lunar Module 9 (LM-9) was relocated to the Apollo/Saturn V Center as part of an initiative to rededicate the center and celebrate the 50th anniversary of the Apollo Program.

Other facilities
The Rotation, Processing and Surge Facility (RPSF) is responsible for the preparation of solid rocket booster segments for transportation to the Vehicle Assembly Building (VAB). The RPSF was built in 1984 to perform SRB operations that had previously been conducted in high bays 2 and 4 of the VAB at the beginning of the Space Shuttle program. It was used until the Space Shuttle's retirement, and will be used in the future by the Space Launch System[75] (SLS) and OmegA rockets.

CR, Maharashtra.
A century ago the Scouts in Crewe served their country well by sending scores of ambulances to France to help with the war effort on the western front.
Gerald Newbrook, who started business Newbrook Engineering Ltd in 1973, made thousands of engineering components for ERF spanning a 30-year period.
In honour of Battle of the Somme commemorations he made a replica Boy Scout ‘Great War’ ambulance, sent to help medical teams deal with sick or injured soldiers.
Gerald, who is the former District Commissioner for South West Cheshire Scouts said: “With this long tradition of vehicle building I thought I would try to re-create a replica of the type of ambulances the Scouts sent to France to help the soldiers involved in the Great War.
The replica is built on the chassis of a small old lorry, which would have been a similar size to the early motor cars.
The project started three years ago when Gerald’s friend Tom Merrall from Whitchurch agreed to help.
After a year or so David Allman from Nantwich joined the team – being an expert joiner he was drafted in to work on the wooden body of the vehicle.
Brian Jones, from Crewe, then agreed to apply the paint finish, which transformed the rather drab-looking vehicle into a stunning example of one of these old ambulances.
“We did not do all the work ourselves,” said Gerald. “Many friends helped, donating their time and sometimes material, free of charge. Also some local businesses helped by donating parts or expertise.
“I wish to thank them all for their help to ensure our Great War Boy Scout ambulance became a successful replica and will probably be unique, which will let people know what the Scouts did to help the soldiers in the First World War.”
Originally it was Lord Baden-Powell who saw the need for more motor ambulances when he visited the trenches in 1915.
He could see the difficulties the troops faced in transferring injured and sick soldiers back from the front to the field dressing stations and hospitals, so, on his return to England, he was determined to see what he could do to help ease the situation.
Following his return from South Africa after the Boer War and the Siege of Makeking, Baden-Powell had made friends with many a wealthy gentlemen who lived in the large country houses.
He knew that most of these influential families had bought a motor-car but during the war these vehicles were not being used as there was no petrol for private motoring and also, quite probably, the young chauffeur had answered the King’s ‘call to arms’ and joined the army or navy.
Baden-Powell idea was to ‘borrow’ as many of these cars as he could, have the coach-built body removed and replace it with a large wooden box, made by the local joiner.
Iron hoops from the blacksmith and a canvas cover completed the vehicle. Red crosses and sign-writing were the finishing touches.
There are reportedly no records of how many conversions were made but various early photographs show many different models of motor-car were used for Boy Scout ambulances.
Oh the MGB, the last great British Sports car?
A motor that refused to die even though British Leyland simply couldn't stop messing around with it. The MGB is an example of a car that went from one of the most loved and lovable cars in British motoring, to what many describe as an empty husk broken and bent for legislation purposes. But the MGB would have its way in the end!
The story behind the MGB begins in 1962, when the car was designed to incorporate an innovative, modern style utilizing a monocoque structure instead of the traditional body-on-frame construction used on both the MGA and MG T-types and the MGB's rival, the Triumph TR series. However components such as brakes and suspension were developments of the earlier 1955 MGA with the B-Series engine having its origins in 1947. The lightweight design reduced manufacturing costs while adding to overall vehicle strength. Wind-up windows were standard, and a comfortable driver's compartment offered plenty of legroom. A parcel shelf was fitted behind the seats.
The car was powered by a BMC B-Series engine, producing 95hp and giving the car a 0-60 of 11 seconds, perhaps not the briskest acceleration, but of course this car was more a comfy little cruiser, ambling about the countryside in sedate fashion admiring the views. The MGB was also one of the first cars to feature controlled crumple zones designed to protect the driver and passenger in a 30 mph impact with an immovable barrier (200 ton).
The roadster was the first of the MGB range to be produced. The body was a pure two-seater but a small rear seat was a rare option at one point. By making better use of space the MGB was able to offer more passenger and luggage accommodation than the earlier MGA while 3 inches shorter overall. The suspension was also softer, giving a smoother ride, and the larger engine gave a slightly higher top speed. The four-speed gearbox was an uprated version of the one used in the MGA with an optional (electrically activated) overdrive transmission. Wheel diameter dropped from 15 to 14 inches.
Upon its launch the MGB was given almost unanimous acclaim, largely due to its advanced and innovative design combined with its beautifully and sleek styling. Previous sports cars of the same calibre had always been levied with a reputation for their ropey nature, with a majority of previous models being simply remodelled versions of the MG's and Triumphs that dated back to the end of and in some cases even before World War II. But the MG was different, and if I'm honest, a large part of its appeal is due to its small, low body, and it's poky round headlights that make it look rather cute. It's the kind of car you could give a name, preferably a girl's one. Either way, the MGB sold in hundreds, disappearing off to all corners of the globe, touring the South of France, storming across the deserts of Southern California on Route 66, or dodging its way through the bustling Indian traffic, these things were adored.
However, the only version available was a soft-top roadster, which didn't appeal to everyone, so in 1965 MG took the B to Italy, and the great styling firm known as Pininfarina, and asked them to pop a roof on their windy little sports car. What resulted was a roof fixture that blended its way perfectly into the rest of the body, a smooth greenhouse cabin that was spacious but still maintained the styling that enthusiasts had come to know so well, going on to be dubbed "The poor man's Aston Martin."
Although acceleration of the GT was slightly slower than that of the roadster, due to its increased weight, top speed improved by 5 mph to 105 mph due to better aerodynamics.
However, tweaks were starting to be made to the MGB formula to try and give it a wider ranging market. Intended to replace the Austin Healey Sprite, the MG MGC was launched in 1967 as a reworked version of the classic MGB, but featuring a 2.9L BMC C-Series engine to up the power.
The problem was that the revised design of the car to incorporate the engine was nothing short of lazy. Instead of redesigning the whole car, MG chose to simply create a huge bulbous lump in the bonnet. The heavier engine also required modifications to the suspension which spoiled the handling. As well as that, the engines were quite poorly built, and later tuning by enthusiasts has proven that the car has the ability to run with 30% more power by carrying out simple modifications to head, exhaust and cam release.
However, the MGC did find some love, in the Royal Family of all places, as in 1967, HRH Prince Charles took delivery of an MGC GT (SGY 766F), which he passed down to Prince William 30 years later. At least one car had a happy ending!
But soon problems came roaring over the horizon like the four horsemen of the apocalypse. A whirlwind of legislation, corporate incompetence and plain old lazy design came right out of nowhere and would soon engulf and attempt to destroy the MGB, but not before stripping the poor thing of its dignity and its good name.
The first disaster to befall this plucky little car, British Leyland, which was formed in 1968 by merging all of Britain's major automotive firms including Rover, BMC (Austin/Morris) and Triumph (which was part of the Leyland Group). To save on costs the lavish chrome grille of the earlier models and spoked wheels were the first to go, but the B could survive without them.
Next up, fitting the car with a Rover V8 that had been developed from a series of Buick Pickup Truck engines. Although this could have been a good thing, this wasn't British Leyland's idea, but in fact belong to professional engine tuner Ken Costello, who, although had been commissioned by British Leyland to create a prototype, had already created a series of MGB's with V8's placed under the hood. British Leyland half-inched this idea and started fitting their own V8's, but went about it all wrong. The powerful 180bhp engine used by Costello for his conversions was replaced for production by MG with a more modestly tuned version producing only 137bhp. Although the car's 193lb-ft of torque meant it could reach 0-60 in 7.7 seconds and go on to a reasonable 125mph top speed, it was a thirsty beast, with only 20mpg. A bit of a territorial hazard admittedly, but it's not a good idea to develop such a gas guzzling car when it was about to smack headlong into the Oil Crisis of 1973. Barely anyone went out and bought it, and the money simply disappeared down the nearest drain.
But so far, the car's lovable external dimensions had yet to be compromised, but we haven't got to the legislation yet, one of those many apocalyptic horsemen I was mentioning earlier. Throughout the 1960's the death of James Dean had resulted in a gradual increase in safety legislation on US Highways, and in order to have a market there, cars had to conform. The height of the headlights, the bumpers, the smoke emissions, the recess of the switches, all of these things were scrutinised and had to be taken into account by car builders.
Indeed America can be owed with introducing many safety features and pieces of legislation we take for granted in modern motoring, but the British manufacturers almost seemed to go out of their way to redesign the cars completely and 100% wrong. In 1974 the glistening chrome was replaced by a gigantic bulbous rubber bumper that protruded from the front of the car like someone's bottom lip!
Other signs of their poor design included the removal of leather seats for something much more mundane, the use of dials and switches from other products such as Austin Allegros and Maxis, as well as door handles that came straight from the Morris Marina.
Internally, British Leyland had botched it with their laziness, choosing not to redesign the car like everyone else so that the headlights were at the required height, but instead placing solid blocks under the suspension to raise the lights to the desired level, but at the same time making the car look like it was going permanently downhill as well as making the handling so light it would slide constantly at speed. The engines were tuned down for emission regulations which made them woefully underpowered and thus they, to use a contemporary phrase, 'couldn't pull the skin off a Rice Pudding!'
Numbers dropped, but British Leyland went to that old trick in the book by using product placement to get by, putting one of their new MGB's in the New Avengers to be driven by Joanna Lumley's character Purdey. As far as I recall though, low slung sports cars aren't the best things to drive if you're in a miniskirt, because getting in and out of them can be quite revealing!
But this wasn't enough to save the MGB's deteriorating sales, in America cars would languish in stockyards and storage warehouses for months on end waiting to be sold, but to no avail. For this, the MG division was making losses of up to £400,000 per week, a clear sign that the ailing MGB had to go the way of all good cars, out of production. On October 21st, 1980, the last MGB rolled off the production line after 18 years, no pomp, no circumstance, just quietly slipping away into history.
After this, the MG brand was lost from its own original cars such as the Midget and the MGB that dated back to the 60's, instead being placed on tuned and slightly modified versions of British Leyland's family cars, including the MG Montego, the MG Maestro and, to the everlasting horror of MG purists although I personally don't think it's that bad, the MG Metro. The factory in Abingdon-on-Thames, where the MGB had been built, closed its gates immediately afterwards as part of the company's rationalisation, striking a blow to the economy of the region and the esteem of those who had been proud to build cars with those two simple letters, MG.
But all was not lost for the MGB, as soon afterwards the cars became fashionably retro, especially in the 1980's and 90's, when 60's examples were bought up largely by foreign markets due to their quintessentially British nature and their synonymous relationship with our country and way of life. Japan especially was a hotspot for old MG products, with Midgets and MGB's being shipped out there by the dozen. So popular were these that Rover Group, the descendants of British Leyland, went on to create a limited edition retelling of the MGB in the form of the MG RV8, constructed in 1993 with 2,000 examples built, the first original MG car to be built since the original MGB ended production in 1980.
Here in the UK, the MG craze kicked off with enthusiasts taking scrapyard shells and run down models and turning them into their own little put-together projects. The MGB has now become one of the most popular little retro sports cars of the modern era, and despite all its faults, even the rubber-bumper British Leyland models make some fantastic kit cars if you want good, wholesome sport fun on a budget!

Chevrolet Camaro
From Wikipedia, the free encyclopedia
"The Chevrolet Camaro is an automobile manufactured by Chevrolet, classified as a pony car and some versions also as a muscle car.
It went on sale on September 29, 1966, for the 1967 model year and was designed as a competing model to the Ford Mustang. The car shared its platform and major components with the Pontiac Firebird, also introduced for 1967.
Four distinct generations of the Camaro were developed before production ended in 2002. The nameplate was revived on a concept car that evolved into the fifth-generation Camaro; production started on March 16, 2009."

------------------------------------------------------------------------------------------
Third generation: 1982–1992
"The third-generation Camaro was produced from 1981 (for the 1982 model year) to 1992.
These were the first Camaros to offer modern fuel injection, Turbo-Hydramatic 700R4 four-speed automatic transmissions, five speed manual transmissions, 15- or 16-inch wheels, a standard OHV 4-cylinder engine, and hatchback bodies. The cars were nearly 500 pounds (227 kg) lighter than the second generation model."
(...)
1982
"The Third-Generation Camaro was released for sale in December, 1981, beginning production on October 12, 1981. The 1982 model introduced the first Camaros with a hatchback body style, and such options as factory fuel injection, and a four-cylinder engine.
The Camaro Z28 was Motor Trend magazine's Car of the Year for 1982.
Three models were available: Sport Coupe, Berlinetta, and Z28.
The Sport Coupe came standard with the 2.5 L (151 cu in) LQ9 four-cylinder engine. The 2.8 L (173 cu in) LC1 V6. the 5.0 L (305 cu in) LG4 V8 were optional. Dog dish-style hubcaps were standard; full wheel covers were optional as were steel, five-spoke 14x7-inch body-colored rally wheels.
The Berlinetta came with the standard 2.8 LC1 V6 or the optional 5.0 LG4 V8. "
(...)
"The Z28 came standard with the 5.0 L LG4 4-bbl V8 or the optional LU5 twin TBI 'Cross Fire Injection' 5.0 L (305 cu in). The carbureted engine was available with either a four-speed manual or three-speed 350 lockup automatic transmission and produced 145 hp (108 kW), while the optional Cross Fire Injection 305 was rated at 165 hp (123 kW).
The new Camaro received positive reviews for its styling and handling, but was also criticized for the low power ratings for the Camaro Z28."
(...)
"The Camaro Z28 was the pace car for the 1982 Indianapolis 500 race, and over 6,000 appearance replicas were sold through Chevrolet dealers. The edition featured special two-tone silver/blue paint and special striping, orange pin-striping on 15-inch (380 mm) Z28 wheels, and a silver/blue interior with six-way Lear-Seigler manually adjustable seating. Engine choices in the pace cars were the same as the regular production Z28. The car that actually paced the event was equipped with a highly modified all aluminum 5.7 L V8 that was not available on the replica cars."

Size comparison. The middle tube is an 807, and the right one a 12AT7. The splash of blue in the middle of the 803 tube is the reflection of a book on my desk.
Celeste blue is one of those iconic cycling colors. It never goes out of style and looks great across any build. This little 54cm F5 Pista Custom was done up for Kristin and it's absolutely stunning. A perfect blend of of classic style with modern components. H Plus Son TB14 rims, our lattice chainring, Nitto handlebars and BROOKS raspberry bartape. It's on the way to the US and will be ready to roll around the West coast.
This is the "pusher" half the the RUWI component system. It is a plywood panel approximately 1-inch thick with a handle and rubberized gasketing applied to the front edge, and an adjustable mechanism for setting the angle of the panel and securing it to the sliding table. Unlike a Fritz & Franz design, this component pivots which I consider a disadvantage.
This alternate pusher component is designed to secure to the sliding table with a lever actuated clamping post. The bumper component has the same rubberized gasketing material along one edge to help secure stock wedged between the two plywood components that make up the system. Also shown in this photo is an alternate plywood "bumper" component.
Lighting components are from Brickstuff. Features push button on/off switch for lights. Switch activated by pressing Yellow round tile. Actual MOC battle scene featuring Sentinel and my custom X-Men coming soon...

One of the biggest and best Veterans Day parades this area has ever seen. More than 100 units with multiple components signed up to march or perform during this year's annual parade, hosted by the Hampton Roads Council of Veterans Organizations (HRCVO). The parade started at 9 a.m. at 16th Street and Atlantic Avenue, and ended at the Tidewater Veterans Memorial at 19th Street, across from the Virginia Beach Convention Center.
This year's Grand Marshal is CPL Johnny Johnson, USMC (Ret.) and MR1 William T. Jones, Jr., USN (Ret.) is this year's Co-Marshal. The parade will include, among others: Marching bands from the U. S. Army Training & Doctrine Command at Fort Eustis, Bayside, Green Run, Kellam, Landstown, Ocean Lakes, Salem and Tallwood High Schools, Honor Guards and/or Motorcycle and Mounted Units from Chesapeake, Portsmouth and Virginia Beach Police Departments and the Virginia Beach Sheriff's Office.
This year's parade is co-sponsored by the La Societe des Quarante Hommes et Huit Chevaux (40 & 8) Voiture Locale 86). It will include military units from the Army, Marine Corps, Navy, and Air Force that represent military installations across the region. Veterans from World War II, Korea, Vietnam, Desert Storm, Desert Shield, Operations Iraqi Freedom and Enduring Freedom will participate, as well as several Tidewater municipal and veterans support organizations, including Naval Junior ROTC Units and Boy Scout and Girl Scout Troops.
The Veterans Day Parade is sanctioned by the Department of Veterans Affairs National Veterans Day Committee and the Mayors of Chesapeake, Norfolk, Portsmouth, Suffolk and Virginia Beach who signed the Veterans Day Proclamation resolving that "citizens, businesses and organizations demonstrate due appreciation, admiration and respect for all veterans who have served our great nation."
Immediately following the parade, a formal ceremony was held at the Tidewater Veterans Memorial. This service included military and civilian honors to the Veterans. Afterwards, there was a luncheon at the DoubleTree Hotel.

I was an early audiophile. Components. Ping-pong stereo. Radio Shack stuff.
The speakers were the Solo-1 model from Radio Shack. The Realistic Solo-1 bookshelf speaker had a woofer and tweeter enclosed in a cabinet. Speaker impedance was 8 ohms with a frequency response of 50 - 14000 Hz. Power handling capacity was 10 watts. The cabinet was 1/2 inch thick particle board with a walnut veneer surface.
This speaker system had an unusually long product run of 16 years. Earlier years had plywood/veneer cases with walnut, mahogany, blond, and oak finish options. Price per speaker hit a low of $15.95 in 1961 and increased to $29.95 in later years.
The turntable was of the single-play variety, with counter-weighted tone arm and the best stylus cartridge I could afford.
The amplifier was probably also from Radio Shack and might have had a power rating of 15-20 watts.
The AM/FM tuner was home-built from a kit I bought through the Heathkit catalog. It was fairly simple with just two control knobs. I don't remember if it was a tube-type or solid state.
I designed the cabinet myself to accommodate the components and a growing LP record collection and had it built by a local cabinetmaker.
The headphones were the most uncomfortable things I've ever worn.

Some background:
The VF-1 was developed by Stonewell/Bellcom/Shinnakasu for the U.N. Spacy by using alien Overtechnology obtained from the SDF-1 Macross alien spaceship. Its production was preceded by an aerodynamic proving version of its airframe, the VF-X. Unlike all later VF vehicles, the VF-X (sometimes referred to as VF-X1) was strictly a conventional/non-transformable jet aircraft, even though it incorporated many structural components and several key technologies that were vital for the transformable VF-1’s successful development that ran in parallel. Therefore, the VF-X was never intended as an air superiority fighter, but rather a flight-capable analogue test bed and proof of concept for the VF-1’s basic layout and major components. In this role, however, the VF-X made vital contributions to systems’ development that were later incorporated into the VF-1’s serial production and sped the program up considerably.
VF-X production started in early 2006, with four airframes built. The flight tests began in February 2007. The first prototype (“01”) was piloted and evaluated by ace pilot Roy Fokker, in order to explore the aircraft’s flight envelope, general handling and for external stores carriage tests. The three other VF-Xs successively joined the test program, each with a different focus. “02” was primarily tasked with the flight control and pilot interface program, “03” was allocated to the engine, vectoring thrust and steering systems development, and “04” was primarily involved in structural and fatigue tests.
In November 2007, the successful VF-X tests and the flights of the VF-X-1 (the first fully transformable VF-1 prototype, which had been under construction in parallel to the VF-X program) led to formal adoption of the “Valkyrie” variable fighter by the United Nations Government.
The space-capable VF-1's combat debut was on February 7, 2009, during the Battle of South Ataria Island - the first battle of Space War I - and remained the mainstay fighter of the U.N. Spacy for the entire conflict.
Introduced in 2008, the VF-1 proved to be an extremely capable craft, successfully combating a variety of Zentraedi mecha, even in most sorties which saw UN Spacy forces significantly outnumbered. The versatility of the Valkyrie design enabled the variable fighter to act as both large-scale infantry and as air/space superiority fighter. The signature skills of U.N. Spacy ace pilot Maximilian Jenius exemplified the effectiveness of the variable systems as he near-constantly transformed the Valkyrie in battle to seize advantages of each mode as combat conditions changed from moment to moment.
The basic VF-1 was deployed in four sub-variants (designated A, D, J, and S) and its success was increased by continued development of various enhancements. These included the GBP-1S "Armored Valkyrie” external armor and infantry weapons pack, so-called FAST Packs for "Super Valkyries” for orbital use, and the additional RÖ-X2 heavy cannon pack weapon system for the VF-1S “Strike Valkyrie” with additional firepower.
After the end of Space War I, the VF-1 continued to be manufactured both in the Sol system and throughout the UNG space colonies. Although the VF-1 would eventually be replaced as the primary Variable Fighter of the U.N. Spacy by the more capable, but also much bigger, VF-4 Lightning III in 2020, a long service record and continued production after the war proved the lasting worth of the design.
The VF-1 was without doubt the most recognizable variable fighter of Space War I and was seen as a vibrant symbol of the U.N. Spacy even into the first year of the New Era 0001 in 2013. At the end of 2015 the final rollout of the VF-1 was celebrated at a special ceremony, commemorating this most famous of variable fighters. The VF-1 Valkryie was built from 2006 to 2013 with a total production of 5,459 VF-1 variable fighters with several variants (VF-1A = 5,093, VF-1D = 85, VF-1J = 49, VF-1S = 30, VF-1G = 12, VE-1 = 122, VT-1 = 68), and several upgrade programs were introduced.
The fighter remained active in many second line units and continued to show its worthiness years later, e. g. through Milia Jenius who would use her old VF-1 fighter in defense of the colonization fleet - 35 years after the type's service introduction.

The model and its assembly:
Another submission to the “Prototypes” group build at whatifmodelers.com in July 2020. Being a VF-1 fan (and have built maybe twenty o these simple Arii kits), adding a VF-X was, more or less, a must – even more so because I had a suitable Valkyrie Fighter kit at hand for the conversion. As a side note, I have actually built something quite similar from a VF-1D many years ago: a fictional, non-transformable advanced trainer, without knowing about the VF-X at all.
Thanks to the “Macross - Perfect Memory” source book, the differences between the transformable VF-1 and its early testbed were easy to identify:
- Fixed legs with faired ducts from the intakes on (thighs)
- Ankle recesses disappeared
- Less and slightly different panel lines on the back and on the nose
- ventral head unit deleted and a respective fairing installed instead
- Levelled underside (shoulder fairings of the folded arms were cut down)
- Leg attachment points on the nose deleted
- No small, circular vernier thrusters all around the hull
- Some new/different venting grills (created mostly with 0.5mm black decal stripes)
Beyond the changes, the VF-1A was basically built OOB. Thankfully, the VF-X already features the later VF-1’s vectored thrust nozzles/feet, so that no changes had to be made in this respect. A pilot figure was added to the cockpit for the beauty pics, and after the flight scenes had been shot, the canopy remained open on a swing arm for static display. For the same reason, the model was built with the landing gear extended.
As a test aircraft, the underwing pylons and their AMM-1 ordnance were left away and the attachment points hidden with putty. I also omitted the ventral gun pod and left the aircraft clean. However, for the flight scene pictures, I implanted an adapter for a display holder made from wire.
In order to emphasize the test vehicle character of the VF-X, I gave the model a scratched spin recovery parachute installation between the fins, using a real world F-22 testbed as benchmark. It consists of styrene profiles, quite a delicate construction. For the same reason I gave the VF-X a long sensor boom on the nose, which changes the Valkyrie’s look, too. Finally, some small blade antennae were added to the nose and to the spine behind the cockpit.
Painting and markings:
To be honest, I have no idea if there was only a single VF-X prototype in the Macross universe, or more. Just one appears in the TV series in episode #33, and lack of suitable information and my personal lack of Japanese language proficiency prevents any deeper research. However, this would not keep me from inventing a personal interpretation of the canonical VF-X, especially because I do not really like the original livery from the TV series: an overall light grey with some simple black trim and “TEST” written on the (fixed) legs. Yamato did an 1:60 scale toy of the VF-X, but it was/is just a VF-1 with a ventral fairing; they added some shading to the basic grey – but this does not make the aircraft more attractive, IMHO.
When I looked at the original conceptual drawing of the VF-X in the “Macross - Perfect Memory” source book, however, I was immediately reminded of the F-15 prototypes from the Seventies (and this program used a total of twelve machines!). These featured originally a light grey (FS 36375?) overall base, to which bright dayglo orange markings on wings, fins and fuselage were soon added – in a very similar pattern to the VF-X. I think the VF-X livery was actually inspired by this, the time frame matches well with the production of the Macross TV series, too, and that’s what I adapted for my model.
In order to come close to the F-15 prototype livery, I gave “my” VF-X an overall basic coat of RAL 7047 “Telegrau 4”, one of German Telekom’s corporate colors and a very pale grey that can easily be mistaken for white when you do not have a contrast reference.
The cockpit received a medium grey finish, the ejection seat became black with brown cushions; the pilot figure is a 1:100 seated passenger from an architecture supplies, painted like an early VF-1 pilot in a white/blue suit. The jet nozzles/feet were painted with Revell 91 (Iron) and later treated with grinded graphite for a more metallic finish. The landing gear became classic white (I used Revell 301, which is a very pure tone, as contrast to the RAL 7047 on the hull), the air intake ducts and the internal sections of the VG wings were painted with dark grey (Revell 77).
For some diversity I took inspiration from the Yamato VF-X toy and added slightly darker (Humbrol 166, RAF Light Aircraft Grey) areas to the hull and the legs. Next, the panel lines were emphasized through a thinned black ink wash, but I did no panel post shading so that the VF-X would not look too dirty or worn.
Onto this basis I applied the orange dayglo markings. On the wings and fins, these were painted – they were applied with spray paint from a rattle can, involving lots of masking. The leading edges on wings and fins were created with grey decal sheet material, too. At this stage, some surface details and more fake panel lines were added with a soft pencil.
The orange cheatline under the cockpit is a personal addition; I found that some more orange had to be added to the nose for visual balance, and I eventually went for the simple, trimmed stripe (TL Modellbau material) instead of trying to apply decal sheet material around the jagged air intakes (F-15 prototype style). The black “TEST”, “VFX” and “U.N. Spacy” markings were designed at the computer and printed on clear inkjet decal paper. Even though the “real” VF-X does not feature the UNS “kite” insignia, I decided to add them to the model. These come from the OOB sheet, which also provided most (slightly yellowed) stencils.
Finally, the model was sealed with a coat of matt acrylic varnish (Italeri).
A rather different VF-1 project (and it is – to my astonishment – #28 in my 1:100 VF-1 Fighter mode collection!!!), with more changes to the basic model kit than one might expect at first sight. VF-X and VF-1 differ considerably from each other, despite identical outlines! However, I like the outcome, and I think that going a different route from the canonical grey/black livery paid out, the bright orange markings really make this VF-X stand out, and it looks IMHO more like a testbed than the “real” aircraft from the TV series.
