I love tweaking these two. They're great basic frames, and a good testbed for ideas. I recently rebuilt their legs and backpacks, and designed new, more size-appropriate weapons for them.

07.57: A third BB15000 has just arrived and its passengers are heading in the crush off to work.

15007 was delivered by Alsthom to SNCF on 22/03/1973.

It was a testbed loco for SNCF from the mid 70s to the 1990s.

Initially renumbered in 1974 as BB7003, it became the prototype for the DC powered BB7200 Class locomotives.

From 1983, it became BB10003 as SNCF worked on asynchronous induction motors.

From 1997 it was converted back to a standard BB15000.

15007 was withdrawn 5 December 2018 as the first of the new withdrawals started again after a 5 year break.

at CFB Trenton Airbase (YTR) on display within the National Air Force Museum

c/n 18.024 - built in 1960 for American Airlines -

operated by MEA between 1971 and 1985 as OD-AFQ -

operated by Pratt & Whitney Canada as a flying engine testbed between 1986 and 2010.

C-FETB was the 720 flying test bed operated by Pratt & Whitney Canada until 2010.

It was equipped to test a variety of engines, for example:

A large turbofan could take the place of the inside / inner engine underneath the right/starboard wing.

A small turbofan could be mounted on the right/starboard side of the forward fuselage.

A turboprop could be mounted in the nose.

The following engine types were tested on C-FETB:

- the International Aero Engines (IAE) V2500 turbofan

- the Pratt & Whitney Canada JT15D turbofan

- the Pratt & Whitney Canada PW300 turbofan

- the Pratt & Whitney Canada PW500 turbofan

- the Pratt & Whitney Canada PW600 turbofan

- the Pratt & Whitney Canada PT6 turboprop

- the Pratt & Whitney Canada PW100 turboprop

One of 154 model 720s manufactured by Boeing between 1959 and 1967, C-FETB was the single remaining operational 720 in the world. On May 9, 2012, the aircraft made its final flight, traveling from Saint-Hubert to CFB Trenton – the last flight ever of a 720. "FETB" as in "Flying Experimental Test Bed"

Eager to preserve this historically significant test bed, Pratt & Whitney Canada (PWC) and the Canada Aviation and Space Museum (CASM) came to an agreement that saw the 720 went on indefinite loan to the National Air Force Museum of Canada, in Trenton, Ontario.

I got so lucky because I got to see British Airways flight 289 land from here, then right after this beautiful plane came on by. But because of British was still on the runway, the Honeywell aircraft had to abort the landing and went back around which is when I took this photo.

Some background:

In the aftermath of the Second World War, Sweden required a strong air defense, utilizing the newly developed jet propulsion technology. The original concept had been designed around a mostly straight wing, but after Swedish engineers had obtained German research data on swept-wing designs, the prototype was altered to incorporate a 25° sweep. In order to make the wing as thin as possible, Saab elected to locate the retractable undercarriage in the aircraft's fuselage rather than into the wings.

While the second P29G was used for high speed trials, the first machine remained in its original guise and took over low speed handling tests. Thanks to the unique wing switch mechanism, the supersonic research program could be held within a very tight schedule and lasted until late 1959. Thereafter, the P29Gs’ potential was of little use anymore, and the engine use agreement with the USA put an end to further use of the two aircraft, so that both P29Gs were retired from service in 1960. The 1st machine, outfitted with standard J29F wings and stripped off of its engines, remained in use as an instructional air at Malmslätt air base 1969, while the second machine was mothballed. However, both airframes were eventually scrapped in 1970.

General characteristics:

Crew: 1

Length: 11.66 m (38 ft 2 in) fuselage only,

13,97 m (45 ft 9 in) with pitot boom

Wingspan: varied*; 11.0 m (36 ft 1 in) with standard 25° sweep wings,

10.00 m (32 ft 9 ¾ in) with experimental 45° wings

Height: 4.54m (14 ft 10 ½ in)

Wing area: varied*; 24.15 m² (260.0 ft²) with standard 25° sweep wings

22.5 m² (242.2 ft²) with experimental 45° wings

Empty weight: 5,220 kg (11,500 lb)

Max. takeoff weight: 8,510 kg (18,744 lb)

Powerplant:

2× Westinghouse J34-WE-42 turbojets, each rated at 3,400 lbf (15 kN) dry thrust

and 4,200 lbf (19 kN) with full afterburner

Performance:

Maximum speed: 1.367 km/h (849 mph) were achieved*

Range: 790 km (490 mi)

Service ceiling: up to 17,250 m (56,500 ft)*

Rate of climb: up to 45 m/s (8,850 ft/min)*

*Varying figures due to different tested wing configurations

Armament:

None installed; provisions for 4x 20mm Hispano Mark V autocannon in the lower front fuselage.

Depending on the mounted wing type, various external loads could be carried, including a wide range of light bombs, 75 mm (3 in) air-to-air rockets, 145 mm (5.8 in) anti-armor rockets, 150 mm (6 in) HE (high-explosive) rockets or 180 mm (7.2 in) HE anti-ship rockets. Due to the lack of complex wiring or fuel plumbing, no guided weapons or drop tanks could be mounted, though.

The kit and its assembly:

Sweden is a prolific whiffing territory, and the Saab 29 offers some interesting options. This highly modified Tunnan, which is actually rather a kitbashing than a mere model kit modification, is/was a submission to the “More or less engines” group build at whatifmodelers.com in summer 2019.

I actually had the idea of a two-engine J29 in the back of my mind for a long time, spawned by a resin conversion set for the Hasegawa B-47 Stratojet kit that came with new intakes and exhaust sections for the four engine pods. The single engine pod parts had been spent a long time ago, but the twin engine parts were still waiting for a good use. Could the exhaust fit under/into a Tunnan…?

I even had a Matchbox J29 stashed away for this experiment long ago, as well as some donor parts like the wings, and the GB eventually offered the right motivation to put those things together that no one would expect to work.

So I pulled out all the stuff and started – a rather straightforward affair. Work started with the fuselage, which was, together with the (very nice) cockpit assembled OOB at first, the nose filled with as much lead as possible and with the lower rear section cut away, so the B-47 resin jet nozzles would end up at the same position as the original RM2B exhaust. Due to the pen nib fairing between them, though, the profile of the modified tail became (visually) more massive, and I had to fill some gaps under the tail boom (with styrene sheet and putty). The twin engines also turned out to be wider than expected – I had hoped for straight flanks, but the fuselage shape ended up with considerable bulges behind the landing gear wells. These were created with parts from drop tank halves and blended into the rest of the lower hill with PSR work. In the same wake the area under the fin was sculpted and re-created, too.

At that point it became clear that I had to do more on the fuselage, esp. the front end, in order to keep the aircraft visually balance. A convenient solution became an F-100 air intake, which I grafted onto the nose instead of the original circular and round-lipped orifice – with its sharp lip the Super Sabre piece was even a plausible change! The fuselage shapes and diameters differed considerably, though, more PSR became necessary.

Next came the wings: I had already set apart a pair of trapezoid wings with a 45° sweep angle – these were left over from a PM Model Ta 183 conversion some time ago. With their odd shape and size they were a perfect match for my project, even more so due to the fact that I could keep the original J29 wing attachment points, I just had to shorten and modify the trailing edge area on the fuselage. The result was very conclusive.

With the new nose and the wings in place, the overall proportions became clearer: still tail-heavy, but not unpleasant. At this time I was also certain that I had to modify the tail surfaces. The fin was too small and did not have enough sweep for the overall look, and the stabilizer, with its thick profile, rounded edges and the single, continuous rudder did not look supersonic at all. What followed was a long search in the donor banks for suitable replacements, and I eventually came up with a MiG-15 fin (Hobby Boss) which was later clipped at the top for a less recognizable profile. The stabilizers were more challenging, though. My solution eventually became a pair of modified stabilizers from a Matchbox Buccaneer(!), attached to the MiG-15 fin.

The design problems did not stop here, though: the landing gear caused some more headaches. I wanted to keep the OOB parts, but especially the main legs would leave the aircraft with a very goofy look through a short wheelbase and a rear axis position too much forward. In an attempt to save the situation I attached swing arms to the OOB struts, moving the axis maybe 5mm backwards and widening the track by 2mm at the same time. Not much in total, but it helped (a little, even though the aircraft is still very tail-heavy)

As a final addition – since the original, wing-mounted pitots of the J29 were gone now and would not go well with the wing-switching idea – I gave the P29G a large, nose-mounted pitot and sensor boom, placed on top of the nose. This part come, like the air intake, from an F-100.

Painting and markings:

I tend to be conservative when it comes to liveries for what-if models, and the P29G is no exception. At first, I thought that this build could become an operational supersonic daylight interceptor (the J29G), so that I could give the model full military markings and maybe a camouflage paint scheme. However, this idea would not work: the potential real life window for such an aircraft, based on the Saab 29, would be very narrow. And aircraft development in the late Fifties made quantum leaps within a very short period of time: While the J29A entered service, work on the Mach 2 Saab 35 was already underway – nobody would have accepted (or needed) a Mach 1 fighter, based on late Forties technology, at that time anymore, and there was the all-weather Saab J32B around, too. The update program with new wings and a more powerful afterburner engine was all that could be done to exploit the Tunnan’s potential, resulting in the (real world’s) J29E and F variants.

I eventually decided that the J29G would only be a prototype/research aircraft, consequently called P29G, and through this decision I became more or less settled upon a NMF finish with some colorful markings. Consequently, the model was painted with various shades of metal colors, primarily Polished Aluminum Metallizer from Humbrol, but also with Humbrol 191 and Matt Aluminum Metallizer as well as ModelMaster Steel Metallizer. Around the exhaust section, I also used Revell 91 (Iron) and ModelMaster Exhaust Metallizer. Some single panels and details were painted with Revell 99 (Aluminum), and I also used generic decal material in silver to simulate some smaller access panels. Grey decal sheet was used to simulate covers for the cannon nozzles.

The cockpit interior was painted, according to Saab 29 standard, in a dark greenish-grey (Revell 67), and bluish grey was used inside of the landing gear wells (Revell 57). The pitot boom received black and white stripes.

For markings I let myself get inspired from the real world Saab 29 and 32 prototypes, which were all marked with a colored “U” tactical code on the fin and also on the front fuselage, simply meaning “Utverding” (= “Test”). I found four red decals, and I also gave the aircraft a yellow cheatline, lent from an Airfix F-86D decal sheet. The Swedish roundels come from a generic aftermarket sheet, most stencils were taken from the Revell OOB sheet and a Printscale J29 sheet.

Before the model was sealed with semi-gloss acrylic varnish from Italeri, some grinded graphite was rubbed onto the rear fuselage, adding a metallic shine and simulating exhaust stains.

A thorough conversion – this has rather evolved into a kitbashing than just a kit conversion: not much from the original Matchbox J29 has been left over. But I like the outcome, even though things developed gradually from the simple idea of changing the number of engines on the Tunnan. One thing led to another. The resulting aircraft looks quite plausible, even though I am not totally happy with the landing gear, which appears to be rather far forward, despite surgical measures to mend the situation. The Ta 183 wings are a very good match, though, and I cannot help but recognize a certain French look, maybe due to the cruciform tail and the oval air intake? The P29G could also, with Argentinian marking, have become a revised version of the FMA Pulqui II?

Another angle on N510AG, this one shows off more of the attachments under the aircraft.

The XK120 was launched in roadster form at the 1948 London Motor Show as a testbed and show car for the new Jaguar XK engine. It caused a sensation, which persuaded Jaguar founder and design boss William Lyons to put it into production.

The "120" in its name referred to its 120 mph (193 km/h) top speed (faster with the windscreen removed), which made the XK120 the world's fastest standard production car at the time of its launch.[4]

It was available in two open versions, first as the roadster (designated OTS, for open two-seater, in America), then also as a drophead coupé (DHC) from 1953 – and also as a closed, or "fixed-head" coupé (FHC) from 1951. The DHC was a more deluxe open model, with wind-up windows, and wood-veneer dashboard and interior door caps, as on the FHC.

The roadster was successful in racing.

Der Jaguar XK 120 war ein zweisitziger Roadster, den Jaguar 1948 als Nachfolger des S.S.100 auf den Markt brachte.

Der Jaguar XK 120 OTS (Open Two Seater, so die etwas umständliche Bezeichnung für den Roadster) besaß einen Sechszylinder-Reihenmotor mit 3442 cm³ Hubraum und 160 bhp.

Ab 1951 gab es den Jaguar XK 120 FHC (Fixed Head Coupé), ein Coupé mit gleicher Motorisierung und 194 km/h Höchstgeschwindigkeit. Bis zur Einstellung 1954 wurden 2678 Stück gebaut.

1953 kam der Jaguar XK 120 DHC (Drop Head Coupé), ein Cabriolet mit gefüttertem Stoffdach und der gleichen Motorisierung, auch als SE, dazu. Es wurde allerdings nur ein Jahr lang angeboten und erreichte in diesem Zeitraum die Stückzahl von 1767 Exemplaren.

Some background:

In the aftermath of the Second World War, Sweden required a strong air defense, utilizing the newly developed jet propulsion technology. The original concept had been designed around a mostly straight wing, but after Swedish engineers had obtained German research data on swept-wing designs, the prototype was altered to incorporate a 25° sweep. In order to make the wing as thin as possible, Saab elected to locate the retractable undercarriage in the aircraft's fuselage rather than into the wings.

While the second P29G was used for high speed trials, the first machine remained in its original guise and took over low speed handling tests. Thanks to the unique wing switch mechanism, the supersonic research program could be held within a very tight schedule and lasted until late 1959. Thereafter, the P29Gs’ potential was of little use anymore, and the engine use agreement with the USA put an end to further use of the two aircraft, so that both P29Gs were retired from service in 1960. The 1st machine, outfitted with standard J29F wings and stripped off of its engines, remained in use as an instructional air at Malmslätt air base 1969, while the second machine was mothballed. However, both airframes were eventually scrapped in 1970.

Depending on the mounted wing type, various external loads could be carried, including a wide range of light bombs, 75 mm (3 in) air-to-air rockets, 145 mm (5.8 in) anti-armor rockets, 150 mm (6 in) HE (high-explosive) rockets or 180 mm (7.2 in) HE anti-ship rockets. Due to the lack of complex wiring or fuel plumbing, no guided weapons or drop tanks could be mounted, though.

The kit and its assembly:

Sweden is a prolific whiffing territory, and the Saab 29 offers some interesting options. This highly modified Tunnan, which is actually rather a kitbashing than a mere model kit modification, is/was a submission to the “More or less engines” group build at whatifmodelers.com in summer 2019.

I actually had the idea of a two-engine J29 in the back of my mind for a long time, spawned by a resin conversion set for the Hasegawa B-47 Stratojet kit that came with new intakes and exhaust sections for the four engine pods. The single engine pod parts had been spent a long time ago, but the twin engine parts were still waiting for a good use. Could the exhaust fit under/into a Tunnan…?

I even had a Matchbox J29 stashed away for this experiment long ago, as well as some donor parts like the wings, and the GB eventually offered the right motivation to put those things together that no one would expect to work.

So I pulled out all the stuff and started – a rather straightforward affair. Work started with the fuselage, which was, together with the (very nice) cockpit assembled OOB at first, the nose filled with as much lead as possible and with the lower rear section cut away, so the B-47 resin jet nozzles would end up at the same position as the original RM2B exhaust. Due to the pen nib fairing between them, though, the profile of the modified tail became (visually) more massive, and I had to fill some gaps under the tail boom (with styrene sheet and putty). The twin engines also turned out to be wider than expected – I had hoped for straight flanks, but the fuselage shape ended up with considerable bulges behind the landing gear wells. These were created with parts from drop tank halves and blended into the rest of the lower hill with PSR work. In the same wake the area under the fin was sculpted and re-created, too.

At that point it became clear that I had to do more on the fuselage, esp. the front end, in order to keep the aircraft visually balance. A convenient solution became an F-100 air intake, which I grafted onto the nose instead of the original circular and round-lipped orifice – with its sharp lip the Super Sabre piece was even a plausible change! The fuselage shapes and diameters differed considerably, though, more PSR became necessary.

Next came the wings: I had already set apart a pair of trapezoid wings with a 45° sweep angle – these were left over from a PM Model Ta 183 conversion some time ago. With their odd shape and size they were a perfect match for my project, even more so due to the fact that I could keep the original J29 wing attachment points, I just had to shorten and modify the trailing edge area on the fuselage. The result was very conclusive.

With the new nose and the wings in place, the overall proportions became clearer: still tail-heavy, but not unpleasant. At this time I was also certain that I had to modify the tail surfaces. The fin was too small and did not have enough sweep for the overall look, and the stabilizer, with its thick profile, rounded edges and the single, continuous rudder did not look supersonic at all. What followed was a long search in the donor banks for suitable replacements, and I eventually came up with a MiG-15 fin (Hobby Boss) which was later clipped at the top for a less recognizable profile. The stabilizers were more challenging, though. My solution eventually became a pair of modified stabilizers from a Matchbox Buccaneer(!), attached to the MiG-15 fin.

The design problems did not stop here, though: the landing gear caused some more headaches. I wanted to keep the OOB parts, but especially the main legs would leave the aircraft with a very goofy look through a short wheelbase and a rear axis position too much forward. In an attempt to save the situation I attached swing arms to the OOB struts, moving the axis maybe 5mm backwards and widening the track by 2mm at the same time. Not much in total, but it helped (a little, even though the aircraft is still very tail-heavy)

As a final addition – since the original, wing-mounted pitots of the J29 were gone now and would not go well with the wing-switching idea – I gave the P29G a large, nose-mounted pitot and sensor boom, placed on top of the nose. This part come, like the air intake, from an F-100.

Painting and markings:

I tend to be conservative when it comes to liveries for what-if models, and the P29G is no exception. At first, I thought that this build could become an operational supersonic daylight interceptor (the J29G), so that I could give the model full military markings and maybe a camouflage paint scheme. However, this idea would not work: the potential real life window for such an aircraft, based on the Saab 29, would be very narrow. And aircraft development in the late Fifties made quantum leaps within a very short period of time: While the J29A entered service, work on the Mach 2 Saab 35 was already underway – nobody would have accepted (or needed) a Mach 1 fighter, based on late Forties technology, at that time anymore, and there was the all-weather Saab J32B around, too. The update program with new wings and a more powerful afterburner engine was all that could be done to exploit the Tunnan’s potential, resulting in the (real world’s) J29E and F variants.

I eventually decided that the J29G would only be a prototype/research aircraft, consequently called P29G, and through this decision I became more or less settled upon a NMF finish with some colorful markings. Consequently, the model was painted with various shades of metal colors, primarily Polished Aluminum Metallizer from Humbrol, but also with Humbrol 191 and Matt Aluminum Metallizer as well as ModelMaster Steel Metallizer. Around the exhaust section, I also used Revell 91 (Iron) and ModelMaster Exhaust Metallizer. Some single panels and details were painted with Revell 99 (Aluminum), and I also used generic decal material in silver to simulate some smaller access panels. Grey decal sheet was used to simulate covers for the cannon nozzles.

The cockpit interior was painted, according to Saab 29 standard, in a dark greenish-grey (Revell 67), and bluish grey was used inside of the landing gear wells (Revell 57). The pitot boom received black and white stripes.

For markings I let myself get inspired from the real world Saab 29 and 32 prototypes, which were all marked with a colored “U” tactical code on the fin and also on the front fuselage, simply meaning “Utverding” (= “Test”). I found four red decals, and I also gave the aircraft a yellow cheatline, lent from an Airfix F-86D decal sheet. The Swedish roundels come from a generic aftermarket sheet, most stencils were taken from the Revell OOB sheet and a Printscale J29 sheet.

Before the model was sealed with semi-gloss acrylic varnish from Italeri, some grinded graphite was rubbed onto the rear fuselage, adding a metallic shine and simulating exhaust stains.

A thorough conversion – this has rather evolved into a kitbashing than just a kit conversion: not much from the original Matchbox J29 has been left over. But I like the outcome, even though things developed gradually from the simple idea of changing the number of engines on the Tunnan. One thing led to another. The resulting aircraft looks quite plausible, even though I am not totally happy with the landing gear, which appears to be rather far forward, despite surgical measures to mend the situation. The Ta 183 wings are a very good match, though, and I cannot help but recognize a certain French look, maybe due to the cruciform tail and the oval air intake? The P29G could also, with Argentinian marking, have become a revised version of the FMA Pulqui II?

The success of the AC-47 Spooky COIN aircraft in Vietnam led to consideration given to an upgraded version in a larger, newer aircraft—the AC-47s already approaching 30 years old during the war. The C-130 was the natural choice, and in 1967 a JC-130A testbed was modified as a gunship. It was initially given the callsign Super Spooky, but later changed to Spectre.

After successful operational trials over both South Vietnam and the Ho Chi Minh Trail in Laos, several more C-130As and C-130Es were modified to Project Spectre standard, mounting four GAU-2/A 7.62mm Minigun gatling cannons and four M61A1 Vulcan 20mm gatling cannons. A few were in turn modified by removing two of the Vulcans in favor of two Bofors 40mm cannon for use against armored targets under Project Surprise Package. Besides their heavy weaponry, the AC-130s also had a comprehensive electronics suite, consisting of night vision equipment, FLIR, improved avionics and navigation equipment, and a digital fire-control system. In addition, AC-130s also carried a modified MAD sensor called Black Crow, which allowed the gunships to detect spark plugs used by North Vietnamese trucks. Following the end of the Vietnam War, the USAF retired all other gunship designs but kept the AC-130 in service, standardizing them as the AC-130H with two Vulcans, a single Bofors, and a M102 105mm howitzer, as the 20mms and the 40mm cannon had proven inadequate against hardened targets (such as tanks) or area attacks.

This proved to be a presicent choice, as AC-130s have seen service in every war fought by the United States since Vietnam: Grenada, Panama, both Gulf Wars, Bosnia, Kosovo, Afghanistan, and Libya. During the Panama operation, Spectre crews successfully decapitated Panamanian Defense Force leadership by destroying the PDF’s headquarters, while they were instrumental in stopping an Iraqi armored column during the Battle of Khafji. In Afghanistan in 2001, AC-130s were the first USAF aircraft to see action, and proved so devastating in their first combat, the Battle of Konduz, that the city fell the next day to Northern Alliance forces without a shot.

The Spectre has been continually improved, and current USAF units use AC-130H/U variants. The AC-130U deletes the two Vulcans in favor of a single trainable GAU-12/A Equalizer 25mm gatling cannon, and has a much more advanced sensor suite over the H model. The “U-Boats” use an APQ-180 synthetic aperature radar and GPS-guided fire control, and can attack two targets simutaneously with twice the ammunition storage of the AC-130H. Increasing scarcity of Bofors parts has led to studies for a replacement weapon. It is also planned in the near future to retire the AC-130H for a new version, the AC-130J, based on the MC-130J Combat Shadow II.

The effect of the AC-130 in any form is devastating; no camp or unit defended by Spectres has ever been overrun by an enemy force. The guns of a Spectre can place a bullet on every square foot of a football field every second until the ammunition runs out. The only real weakness of the AC-130 is its vulnerability to ground fire, though most threats to the Spectre from light antiaircraft fire are usually eliminated quickly, while heavier flak can be defeated by escorts. Spectres carry a range of powerful ECM and countermeasures against SAMs, but aside from shoulder-fired SAMs, AC-130s rarely operate in such a high-threat environment and never in areas where enemy fighters could intercept them.

Currently, the USAF has a single wing of AC-130s, with AC-130Hs being slated for retirement soon, while the AC-130U will serve for some years to come; plans are underway to replace them with more advanced AC-130Js, based on the C-130J. The armament package that the AC-130J has not yet been determined, but is known to include precision-guided weapons.

As Dad planned to convert a C-130H model to an AC-130, he needed to get closeups of the gun system. This shot shows the 40mm Bofors cannon (on the left) and the M102 105mm howitzer (on the right). The dome between the two is the fire control radar. These two weapons systems are still used on the current AC-130U, and will be familiar to players of the "Call of Duty: Modern Warfare" series of games. This aircraft belonged to the 1st Special Operations Wing at Hurlburt Field, Florida.

Due to the pen nib fairing between them, though, the profile of the modified tail became (visually) more massive, and I had to fill some gaps under the tail boom (with styrene sheet and putty). The twin engines also turned out to be wider than expected – I had hoped for straight flanks, but the fuselage shape ended up with considerable bulges behind the landing gear wells. These were created with parts from drop tank halves and blended into the rest of the lower hill with PSR work. In the same wake the area under the fin was sculpted and re-created, too.

At that point it became clear that I had to do more on the fuselage, esp. the front end, in order to keep the aircraft visually balance. A convenient solution became an F-100 air intake, which I grafted onto the nose instead of the original circular and round-lipped orifice – with its sharp lip the Super Sabre piece was even a plausible change! The fuselage shapes and diameters differed considerably, though, more PSR became necessary.

Next came the wings: I had already set apart a pair of trapezoid wings with a 45° sweep angle – these were left over from a PM Model Ta 183 conversion some time ago. With their odd shape and size they were a perfect match for my project, even more so due to the fact that I could keep the original J29 wing attachment points, I just had to shorten and modify the trailing edge area on the fuselage. The result was very conclusive.

With the new nose and the wings in place, the overall proportions became clearer: still tail-heavy, but not unpleasant. At this time I was also certain that I had to modify the tail surfaces. The fin was too small and did not have enough sweep for the overall look, and the stabilizer, with its thick profile, rounded edges and the single, continuous rudder did not look supersonic at all. What followed was a long search in the donor banks for suitable replacements, and I eventually came up with a MiG-15 fin (Hobby Boss) which was later clipped at the top for a less recognizable profile. The stabilizers were more challenging, though. My solution eventually became a pair of modified stabilizers from a Matchbox Buccaneer(!), attached to the MiG-15 fin.

The design problems did not stop here, though: the landing gear caused some more headaches. I wanted to keep the OOB parts, but especially the main legs would leave the aircraft with a very goofy look through a short wheelbase and a rear axis position too much forward. In an attempt to save the situation I attached swing arms to the OOB struts, moving the axis maybe 5mm backwards and widening the track by 2mm at the same time. Not much in total, but it helped (a little, even though the aircraft is still very tail-heavy)

As a final addition – since the original, wing-mounted pitots of the J29 were gone now and would not go well with the wing-switching idea – I gave the P29G a large, nose-mounted pitot and sensor boom, placed on top of the nose. This part come, like the air intake, from an F-100.

Painting and markings:

I tend to be conservative when it comes to liveries for what-if models, and the P29G is no exception. At first, I thought that this build could become an operational supersonic daylight interceptor (the J29G), so that I could give the model full military markings and maybe a camouflage paint scheme. However, this idea would not work: the potential real life window for such an aircraft, based on the Saab 29, would be very narrow. And aircraft development in the late Fifties made quantum leaps within a very short period of time: While the J29A entered service, work on the Mach 2 Saab 35 was already underway – nobody would have accepted (or needed) a Mach 1 fighter, based on late Forties technology, at that time anymore, and there was the all-weather Saab J32B around, too. The update program with new wings and a more powerful afterburner engine was all that could be done to exploit the Tunnan’s potential, resulting in the (real world’s) J29E and F variants.

I eventually decided that the J29G would only be a prototype/research aircraft, consequently called P29G, and through this decision I became more or less settled upon a NMF finish with some colorful markings. Consequently, the model was painted with various shades of metal colors, primarily Polished Aluminum Metallizer from Humbrol, but also with Humbrol 191 and Matt Aluminum Metallizer as well as ModelMaster Steel Metallizer. Around the exhaust section, I also used Revell 91 (Iron) and ModelMaster Exhaust Metallizer. Some single panels and details were painted with Revell 99 (Aluminum), and I also used generic decal material in silver to simulate some smaller access panels. Grey decal sheet was used to simulate covers for the cannon nozzles.

The cockpit interior was painted, according to Saab 29 standard, in a dark greenish-grey (Revell 67), and bluish grey was used inside of the landing gear wells (Revell 57). The pitot boom received black and white stripes.

For markings I let myself get inspired from the real world Saab 29 and 32 prototypes, which were all marked with a colored “U” tactical code on the fin and also on the front fuselage, simply meaning “Utverding” (= “Test”). I found four red decals, and I also gave the aircraft a yellow cheatline, lent from an Airfix F-86D decal sheet. The Swedish roundels come from a generic aftermarket sheet, most stencils were taken from the Revell OOB sheet and a Printscale J29 sheet.

Before the model was sealed with semi-gloss acrylic varnish from Italeri, some grinded graphite was rubbed onto the rear fuselage, adding a metallic shine and simulating exhaust stains.

A thorough conversion – this has rather evolved into a kitbashing than just a kit conversion: not much from the original Matchbox J29 has been left over. But I like the outcome, even though things developed gradually from the simple idea of changing the number of engines on the Tunnan. One thing led to another. The resulting aircraft looks quite plausible, even though I am not totally happy with the landing gear, which appears to be rather far forward, despite surgical measures to mend the situation. The Ta 183 wings are a very good match, though, and I cannot help but recognize a certain French look, maybe due to the cruciform tail and the oval air intake? The P29G could also, with Argentinian marking, have become a revised version of the FMA Pulqui II?

RFA Proteus (K60) is a ship of the Royal Fleet Auxiliary within His Majesty's Naval Service of the United Kingdom. Its roles being a platform for Remotely Operated Underwater Vehicles (ROUVs) and a testbed for new specialist capabilities, required for monitoring waters important to UK interests. Acquired in 2023, the ship entered drydock at Cammell Laird for modification into a Multi-Role Ocean Surveillance Ship (MROSS). She formally entered service in October 2023.

The ship was formerly named MV Topaz Tangaroa in 2017–2022, and was used as a platform supply vessel operated by P&O Maritime Logistics.

Flash Airlines (this Flash Airlines...) was a Nigerian Cargo Company active between 1985 and 1996 with 2 DC-8s.

5N-ATZ (c/n 45965 l/n 346, series -55CF) was built in 1968 for Iberia, leased to Aviaco and Lacsa and at the end sold to Jet Avionics/Quite Nacelle Corp in 1985. The plane will be used as testbed for JT3D engine hush-kit certification and then sold to FB Air in June 1987. It will later be sold to EAS Cargo and leased by Flash Airlinesbetween 1988 and 1992.

The slide was taken in RTM and is dated April 1990.

Class 47 no 47601 approaches Darnall station on an eastbound mgr train on 24 October 1977. This loco had been built as D1628 at Crewe in 1964, and then renumbered 47046 under TOPS in 1973. In 1977 it was selected as a testbed for the projected Class 56 and fitted with a 16-cylinder Ruston 16RK3CT engine rated at 3250 hp. As such it was renumbered 47601 in January 1977.

Two years later it was selected as a testbed for Class 58 and fitted with a 12-cylinder Ruston engine rated at 3300 bhp. 47601 was then renumbered 47901. 47901 carried this engine until withdrawal from CF in March 1990 - the loco was cut up by MC Processors in Glasgow in March 1992.

Arriva London Ltd.:

DW411 was retrofitted with a new driveline, as a testbed for what would become the Wrightbus StreetDeck. The original 6-cyl Cummins ISBe engine was replaced with the Mercedes-Benz (Daimler) OM934. The vehicle caught fire shortly after arrival to the London fleet in 2011, so instead of being written off, she was given a new lease of life, and a slightly different identity!

A number of the artists participating in the residency present their results – ranging from fundamental experimentation to full-fledged new works. You are cordially invited to join this event and experience disorienting acoustic explorations, morphing and breathing architectures and pulsating audiovisual fields piercing Sphæræ’s ethereal atmosphere.

Towards the end of the 1970's, British Leyland was in a state of absolute despair. Shoddy and dated car designs married to biblical unreliability meant the company was facing near meltdown, and obviously came to the conclusion that they needed someone else to take the helm before the ship properly sank. Enter the Japanese, more to the point, Honda!

Since the 1960's, the Japanese had shown the world that they can mass-produce reliable cars, and thus were raking in sales by the million as people turned from their flaky European models to the highly efficient Japanese alternatives. Desperate to stop their market being swept out from under them, European Manufacturers imposed heavy import taxes on Japanese imports so as to try and price them out of the market, which meant builders such as Toyota, Honda and Mitsubishi were losing a fortune. The alternative past this blockade was to combine their efforts with some of the more struggling car companies of Europe so as to create hybrid cars.

And thus the Triumph Acclaim was born!

Based almost solely on the Honda Ballade, essentially all that differentiated it was the Triumph badge, and the fact that the car was built at the Cowley Plant near Oxford using the former production lines of the Austin Maxi. The intention largely was to replace the 10 year old Triumph Dolomite as the 4-door saloon of the company. Unlike the Ballade however, the car did come with much more luxury features as with a Triumph badge, the car was intended to be more higher market than the conventional Japanese equivalent. But most importantly, the car has the distinction of being the first truly reliable British Leyland car (and it only took them 12 years to get it right!)

Basically, the car's major components were built in Japan and shipped to Cowley, where they were placed into the locally built bodyshells. Build quality was very good too, with the leaky panels and rough ride seemingly absent, and holds the record for the fewest warranty claims on a British Leyland car. However, Japan may have shown Europe how to build a reliable car, but they didn't know how to build a car that didn't rust. Much like it's Japanese counterparts, the Acclaim rusted like crazy. In Japan this was seen as planned obsolescence, with the intention being that a new model would replace it in two or three years time. But in Britain, cars are built to last, with models going unchanged almost completely for years and even decades. Examples being the Mini, which didn't change in any way, shape or form between its launch in 1959 and its demise in 2000!

But still, despite the terrible rusting problem, the car's reliable nature resulted in 133,000 cars being sold, and became the first Triumph to be within the Top 10 highest selling cars since 1965. However, in the end the Acclaim's show of being a good, reliable car was merely a testbed for the variety of other Japanese style products British Leyland intended to push in the near future. After only 4 years of production, the Triumph Acclaim was shelved in 1984 along with many other British Leyland products such as the Austin Ambassador and the Morris Ital so as to rationalise the company into a small number of highly reliable machines based off the Triumph Acclaim's Japanese based success. From the Acclaim, the Rover 200 was a direct descendant, being based heavily on the next generation Honda Ballade, but also spurring from this plucky car was the mechanicals of the Austin Maestro and Montego.

The ending of Acclaim construction in 1984 also brought the end to the Triumph badge itself on motorcars. Although Triumph still exists on motorbikes, the car division has long since perished, together with Austin and Morris. As for the Acclaim itself, it is truly one of those rarities you won't find everyday. Today only 488 are left, which, although much more than the remaining Ital's and Ambassadors of the same period, is still a very low number. But even so, the Triumph Acclaim did show British Leyland how to make a reliable machine, even though it technically wasn't a British machine in the first place!
