Pt. 1/2
The “sky-crane” helicopter concept was born with the CH-37 Mojave in the 1950s. Sikorsky continued testing and development with the piston-engined S-60 prototype. While Sikorsky was beginning work on the S-64 in 1961, the sole S-60 prototype crashed.
Sikorsky’s and the Army’s investment in the S-64 program soon paid off. The program delivered an extremely versatile, efficient, and rugged rotorcraft; its first flight was on May 9, 1962. The military variant, the CH-54 Tarhe (meaning “The Crane”), was named after an 18th-century Native American chief while the civil variant kept the company designation S-64 and is referred to as the Skycrane. The Tarhe was deployed to Vietnam in 1965, performing a multitude of roles during throughout the conflict. The skycranes mainly delivered construction equipment and 155mm howitzers to hilltop firebases and frontline airfields. By 1967, there were 3 heavy helicopter companies (10 skycranes each) in service with the U.S. Army in Vietnam under the umbrella of the 1st Air Cav. During its 8 years of service in Southeast Asia, only one was shot down, but 8 were lost to operational causes. It was phased out of Army and National Guard service during the 70s and 80s, gradually being replaced by the CH-47 Chinook. 105 Tarhes were made (As, Bs, and pre-production models), and Erikson Aircrane still produces the S-64 to this day (31 have been made since the 90s).
General Specifications:
Crew - 3
Dimensions - length: 88.5 ft, height: 25ft 5in
Rotor - diameter: 72ft, area: ~4,000 sqft
Weight - ~19,000-20,000 lbs
Max Takeoff Weight - 47,000 lbs
Payload - 21,000 lbs
Powerplant - two Pratt & Whitney T73 turboshafts (4,500 hp each)
Max Speed - 130 kn (150 mph)
Range - 200 nmi (230 mi)
Rate of Climb - 1,330 ft/min (6.8 m/s)
The model:
Features - detailed cockpit with opening doors (easily accessible), working main winch, 4 external hooks, geared rotors, stowable blades, blade holders, cargo pod with technic motor and battery box for motorization (I’ll have to design some more cargo pods in Studio that actually have a detailed interior)
The stickers are from various Brickmania Huey sticker packs. I also based the main rotor design on the Brickmania CH-53E (which was derived from the Skycrane irl) main rotor. It’s generally the same technique, but I had to do some troubleshooting to get it down to 6 blades instead of 7.

Metra decided to see if F59PH 97 was willing to make a problem-free trip to Elgin on Express train 2235 during the evening rush hour.
It made it without any obvious reportable issues, but these Canadian Hand-Me-Downs seemed to be plagued with issues despite the best troubleshooting from Western Avenue's Finest.
Hopefully, someday these things will start being reliable and start to return on the investment.

It became apparent in the early 2000s that the over 40 year old Nimitz Class design was in need of replacement. In 2005, Newport News Shipbuilding was awarded a contract to begin development on America’s newest class of super carriers. In 2009, she was laid down. By mid 2013, she was structurally complete. At the end of the year, she was christened. In 2017, she was commissioned, replacing the 56 year old USS Enterprise CVN-65. On July 28, 2017; the first arrested landings and catapult launch took place. As of 2021, the ship is still under going testing and troubleshooting of its electromagnetic launch system. For this reason, the ship has not yet been deemed combat ready.
Some design improvements over the Nimitz include: increased flight deck space as a result of moving and shrinking the island and eliminating lift 3, electromagnetic catapults, new phased-array radars built into the island, and a more efficient power plant.
Specifications:
Length - 1,106ft
Beam - 256ft
Height - 250ft
Displacement - 100,000 long tons
Power Plant/Propulsion - 2x A1B nuclear reactors, turbines, 4 screws
Performance - 30+ knots
Compliment - ~4,500
Armament - 2 Sea Sparrow launchers, 2 RAM launchers, 3 phalanx CIWS
Aircraft - 75+
I kept the draft and bow from the Reagan (minus the bulbous bow), and rebuilt everything else from scratch. This model is actually about 200 pieces more than the Reagan. I also cleaned up the internal structure. And just like the Reagan, it was a blast to design.
Testing, Testing, ... BANG!!!
Nondestructive testing
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage.[1] The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology.[2] Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing,[1] and low coherence interferometry.[3][4] NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art.[1] Innovations in the field of nondestructive testing have had a profound impact on medical imaging, including on echocardiography, medical ultrasonography, and digital radiography.
Methods[edit]
NDT methods may rely upon use of electromagnetic radiation, sound, and inherent properties of materials to examine samples. This includes some kinds of microscopy to examine external surfaces in detail, although sample preparation techniques for metallography, optical microscopy and electron microscopy are generally destructive as the surfaces must be made smooth through polishing or the sample must be electron transparent in thickness. The inside of a sample can be examined with penetrating radiation, such as X-rays, neutrons or terahertz radiation. Sound waves are utilized in the case of ultrasonic testing. Contrast between a defect and the bulk of the sample may be enhanced for visual examination by the unaided eye by using liquids to penetrate fatigue cracks. One method (liquid penetrant testing) involves using dyes, fluorescent or non-fluorescent, in fluids for non-magnetic materials, usually metals. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles (either liquid or dry dust) that are applied to a part while it is in an externally magnetized state (magnetic-particle testing). The particles will be attracted to leakage fields within the test object, and form on the objects surface. Magnetic particle testing can reveal surface & some sub-surface defects within the part. Thermoelectric effect (or use of the Seebeck effect) uses thermal properties of an alloy to quickly and easily characterize many alloys. The chemical test, or chemical spot test method, utilizes application of sensitive chemicals that can indicate the presence of individual alloying elements. Electrochemical methods, such as electrochemical fatigue crack sensors, utilize the tendency of metal structural material to oxidize readily in order to detect progressive damage.
Analyzing and documenting a non-destructive failure mode can also be accomplished using a high-speed camera recording continuously (movie-loop) until the failure is detected. Detecting the failure can be accomplished using a sound detector or stress gauge which produces a signal to trigger the high-speed camera. These high-speed cameras have advanced recording modes to capture some non-destructive failures.[5] After the failure the high-speed camera will stop recording. The capture images can be played back in slow motion showing precisely what happen before, during and after the non-destructive event, image by image.

I wasted a lot of time today trying to fix an email problem. After 4+ hours of troubleshooting, it all came down to 1 stupid checkbox that needed to be marked. Why this suddenly became an issue at 1:00 this afternoon is still a mystery, but my kids were off of school today and instead of spending that time playing with them, I wasted it on this darn machine!
I felt just awful and apologized like crazy as I tucked them into bed tonight. Priorities Kelly...

I had just met my seat mate and he was waiting to see if the seat on the other side of him remained free so he could spread out and put an empty seat between us. Then someone on crutches slowly navigated down the aisle. A quiet and polite air about him. He may not have needed help, but he humbly accepted it when folks offered to put his crutches or bag up. Sporting an army shirt, signal corp hat, and artificial legs emblazoned with the American flag; he seemed to have close ties to America. My seatmate asked him whether he was a vet and then proceeded to thank him for his service. He humbly accepted the compliment. Shortly thereafter a phrase I heard him repeat, "Life is Good" came up. Meet Johnnie.
The more we talked to Johnnie the more we were in awe. An unassuming gentleman who had been traveling the world and taking part in the Valor Games. He was coming to OKC to train. His favorite sports were archery, shot put, and discus; though he participated in more. One of his current goals was to work on his bench press. Already pressing 358lbs and looking to press 375lbs!
I asked him about his legs as they were quite decorated and even the tops were too. Their look was very customisable. He mentioned they had computers in them. I didn't even know they had such technology! USB ports in each could be used for upgrades and troubleshooting. He said they were old tech and that there are more sophisticated ones these days. These were walking legs, but he had several sets for different sports.
During the flight the engine noise made conversation difficult. My seatmate was not the talking sort and retreated into his earbuds and I thought it rude to lean around him to talk with Johnnie some more, so we each sat through the flight. When we landed we all joined in conversation again and both me and my seat mate gladly waited for the seat to deplane. We were in no hurry and it was a great opportunity to learn from this man.
Johnnie said this was his last year as a competitor in the games and then he had to retire from them. 'Surely you are not too old', both my seatmate and I were thinking. We were informed that 71 was the last year he could play. Next year he would make the move to trainer, but he intended to still be associated with them.
71 and he was still doing sports like a champion? Traveling the world? Bench pressing more than I could ever even imagine? Yes. Something he said to us earlier in our talk came back to my mind, 'you can either watch life or participate'. When his legs were taken from him by a rocket blast he did not stop living.

i need to find her some more regal clothes, but i guess this will do for hanging out around the palace, troubleshooting some new inventions...
That's what I always do with all my creations. When I've built something I place it on the toilet and watch it from the bath tub for an hour. This is a method of troubleshooting, the hot water makes you relaxed and more innovative. :-)

went to the beach with dana today :D point pleasant ;) looks summery, but was FREEZING. couldn't take any water shots!
will post the whole adventure + raw troubleshooting + 30 million photos on the blog later.
(leaving for a cherry blossom festival! tata. i will leave you with this photo until i return)

Sometime in the near past (when Big Bang occured) I mentioned that my internet problems were solved (or that's what I thought).
Here is what happened [warning: whining begins here :) ]
The modem/router combo (Linksys WCG 200) had a problem connecting to the 'net and Cox, my ISP suggested I talk with Linksys tech support and that I did. After hours of troubleshooting, the tech person confirmed the problem and said they would send a replacement and I received it last week (Big Bang!!).
I could connect to the internet. However, connecting wireless was a problem. When I was on wireless and tried connecting to any page, when it started loading (typically less than 20 seconds) the modem would reset. It would start connecting to the ISP and after 3 minutes, it would be connected, and online. And it would stay online for 20 seconds before it went into the same cycle again. With a 6 ft long coax cable and 6 ft long LAN cable, sitting that close to the TV (and modem) to connect was, to say the least, pain. And that was why I was missing from the internet.
I called Linksys again, and after hours of troubleshooting, they said they had sent a defective replacement and would send another (add one week here). My new WCG200 arrived yesterday and I called Cox and updated router info and connected. It worked. I connected wireless, and eeks.. same thing.
Now before even trying to call Linksys, I wanted to do my own research and googled my problem. What I stumbled upon was a bit more than amazing. Linksys community forum had a topic on this and there were close to 200 people complaining about the same thing for that model.
forums.linksys.com/linksys/board/message?board.id=Cable&a...
Apparently, no person in Linksys' R&D is reading it. The first complaint is over a year and a half old and the latest is a day old. If someone from Linksys is reading this, please, could you ask them to stop manufacturing WCG200?
Thanks to my friends, I have a very long (100 ft, maybe :P) LAN cable. Until I buy another *working* router. If you decide to walk in to my apartment, watch out, you may trip and fall :-)
he perils of Sour Patch Kids
They’ll do more than just rot your teeth. They’ll also break your computer.
My laptop stopped turning on. I went through all the troubleshooting with no success. I suspect the problem is not a virus or a hacker, but the sour gummy candy that “somehow” got melted into the vents.
I ended up buying a new laptop and losing a few files. My pro advice: don’t put your warm laptop into a bag with spilled Sour Patch Kids.

On an unrelated topic to this image, be cautious with the new 11.3 update to Lightroom. After much work and issues, I discovered that it's incompatible with my catalog from 11.2. TONS of troubleshooting and testing before simply uninstalling 11.3 and reinstalling 11.2, but I'm now marooned on this version. I've opened a ticket with Adobe and sent them a copy of my catalog file, but figured I'd mention something in case anyone else ran into the issue.

I've spent that last few weeks the process of troubleshooting and recovering from a slowly progressing hard drive crash. Still reloading my system and software, but I thought I'd drop in to say I'm still alive. Sooner or later, I'll be back to normal.

After months of troubleshooting, re-doing, and ventilating, the wig is finally looking like how I wanted it to look. And nope, IT AIN'T DONE YET -- you can see a bit of where a huge bald spot still remains at the back of the head.
Am troubleshooting a clicker/remote issue and the xfinity assistant wanted me to do a system reset (reboot). So I unplugged all the cords, waited the requisite time, and plugged them back in. Same issue— the voice activated part doesn’t work. Hasn’t worked since day1. So I’m taking a break before I put things back……

This is excess extruded Acrylonitrile Butadiene Styrene (ABS) from a LEGO factory. The ABS pellets were heated in preparation for injection molding, but the liquid plastic was ejected from the machine before it could be injected into the mold. This is common when troubleshooting molds, and the waste plastic is typically discarded or sent for recycling at another company. Despite its fluid look, this ABS has cooled to about the typical hardness that you'd expect from LEGO bricks.

Moulding defect:
Splay marks
Alternative name:
Splash mark or silver streaks
Description:
Usually appears as silver streaks along the flow pattern, however depending on the type and color of material it may represent as small bubbles caused by trapped moisture.
Causes:
Moisture in the material, usually when hygroscopic resins are dried improperly. Trapping of gas in "rib" areas due to excessive injection velocity in these areas. Material too hot, or is being sheared too much.

Contrast between a defect and the bulk of the sample may be enhanced for visual examination by the unaided eye by using liquids to penetrate fatigue cracks. One method (liquid penetrant testing) involves using dyes, fluorescent or non-fluorescent, in fluids for non-magnetic materials, usually metals. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles (either liquid or dry dust) that are applied to a part while it is in an externally magnetized state (magnetic-particle testing). The particles will be attracted to leakage fields within the test object, and form on the objects surface. Magnetic particle testing can reveal surface & some sub-surface defects within the part. Thermoelectric effect (or use of the Seebeck effect) uses thermal properties of an alloy to quickly and easily characterize many alloys. The chemical test, or chemical spot test method, utilizes application of sensitive chemicals that can indicate the presence of individual alloying elements. Electrochemical methods, such as electrochemical fatigue crack sensors, utilize the tendency of metal structural material to oxidize readily in order to detect progressive damage.
Analyzing and documenting a non-destructive failure mode can also be accomplished using a high-speed camera recording continuously (movie-loop) until the failure is detected. Detecting the failure can be accomplished using a sound detector or stress gauge which produces a signal to trigger the high-speed camera. These high-speed cameras have advanced recording modes to capture some non-destructive failures.[5] After the failure the high-speed camera will stop recording. The capture images can be played back in slow motion showing precisely what happen before, during and after the non-destructive event, image by image.
