Since the trivia questions seem to be running a little dry, let's try these:
1. Name as many transport aircraft as you can that were converted to or from gliders.
2. Name the aircraft that was referred to as "The Ass Ender".
3. The British suggested a novel way to dodge enemy gunfire while flying a P-47. What was it?
4. How many Martin JRM's were built, and what became of them?
5. What is the purpose of an oil dilution system?
6. Name as many jet aircraft as you can that were built primarily of wood.
7. What is a PRT?
8. Name as many aircraft as you can that are/were powered by coupled engines.
9. Name the oldest aircraft type currently in service with the US military.
10. What US naval attack aircraft, when its nuclear weapons delivery system failed to perform as expected, was converted to a recon aircraft? What was the problem that caused the change?
The Galvin clock is now running....... ;D

1) DC- 3; Me 363, C-123
2)
3) Pilots were suggested to un strap, and run around inside the fuselage to dodge gun fire.
4) Six. Two of them are still dousing fires.
5) To reduce the viscosity of oil so that it could reach vital points inside the engine during, and hopefull prior to startup.
6) Does the Natter count ? Vampire had a wooden fuselage pod.
7) PRT = Power Recovery Turbine... 3 were used on some models of the Wright R-3350. Each fed by 6 cylinders. The turbines were geared back to the crankshaft, each one contributing an additional 300 hp to the crank.....
8) Bell 212 (in fact, all multi engine helicopters) Saunders roe Princess and Brabazon, Pogo......
9) gotta be the B-52
10) WAG ........A4D

#10
A-5 Vigilanti
Redesignated RA-5C
The internal bomb bay (rear ejecting) did not work as designed. An over the shoulder deployment was not possible.

Not offering any answers, but in looking for some, found this website. Lots of stuff there www.globalaircraft.org/As a matter of fact, in just a quick look around there found this oddity. One could cheat and look at the image name, but I know no one here would do that....

Galvin had that one in one of his quizzes on flightlines........awhile ago..

1. Name as many transport aircraft as you can that were converted to or from gliders.
Chase CG-18/MS-8 Avitruk, Gotha 242/244, Messerschmitt 321/323 "Gigant", CG-4A/XPG-2. The CG-15 glider also had powered variants that were not produced. And in the other direction there was the C-47/XCG-17
5. What is the purpose of an oil dilution system?
To reduce the viscosity of oil and thus allow the engine to even turn over at very low temperatures. It was considered a top secret feature even though it was used by other Air Forces than the U.S.
6. Name as many jet aircraft as you can that were built primarily of wood.
Me-163 (Wood wings), DeHavilland Vampire/Venom (Fuselage forward of firewall),
7. What is a PRT?
Power Recovery Turbine. An exhaust driven turbine that feeds power directly back into the crankshaft through a hydraulic coupling rather than driving a compressor. The Wright R-3350 "Turbo-Coumpound" engine had three of these mounted 120 degrees from each other and as a result was the most powerful piston aircraft engine in terms of power per cubic inch ever built. Our Connies had PRT equipped R-3350s that could achieve 3750 HP each in high blower on 145 octane fuel.
8. Name as many aircraft as you can that are/were powered by coupled engines.
Heinkel 177, Lockheed P-58 "Chain Lightning", Saro Princess, Fisher P-75 "Eagle", Vought XF-5U "Flapjack", Bell XV-15 tiltrotor, V-22 Osprey, Vought XC-142A tiltrotor, Harlow PJC-5 w/ "Unitwin" engine,

6. Name as many jet aircraft as you can that were built primarily of wood.Me-163 (Wood wings... Technically, the Me 163 was a rocket fighter, not a jet fighter. D

Nice try Demon. ;D Rocket and turbojet fighters are all jets because they aren't pulled through the sky by a propeller. There are jet engines and reaction engines and both rely on jet thrust rather than a propeller to produce thrust. They just produce that jet of high speed air a bit differently. Arado 234s, Me-262s and Me-153s were all called "jets", "blow jobs", or "jet jobs", by the american crews they encountered.

Did you fly the connies, Dave? I read a history of Flying tigers long ago, and it made no bones about the maintenace headaches those engines caused......(in fact I still remember the title of the chapter : Trouble - Turbo Compounded. )......don't remember the name of the book, though.................figures!

Looks like you guys got all of them again, good job! Sorry to be so long getting back here, they actually allowed me to take a vacation. ;D
FWIW--the B-52 is indeed the oldest aircraft in the US military, and the longest serving bomber ever built. 94 H models remain, and are expected to see service well into this century. The Buff entered service in 1955. The next two in line are the Cessna T-37 and the Boeing KC-135, both of which entered service in 1957 and are still on active duty.
Wayne, those 3350 turbo compounds were something to see, but not terribly reliable. They would leak oil by the gallon because the PRT seals wouldn't take the heat. When the system worked, it was pretty impressive, but it took a LOT of maintenance to get them to that point!
Darin, welcome back! Good to see you again...
