Now, I want to look that hup. HTF do you capture a Flying Fortress? I wasn't aware of any American airfields being captured by Nazis. The Japanese, we went back and forth with, but by the time we got involved with the War in Europe, Germany was already running out of Gas. (Because they hung a left at Ukrain, instead of capturing the oil fields they needed, and decided on attacking Moskov with Tanks. Brilliant!)
Now I have this fantasy of elite Fallschirmjägergeweh skydiving from converted Me163s wit FG43s, and magnetst to latch onto the wings, and set up bipods. [Let us in, or we shoot!] Signs to commit sky piracy en route from the Battle of Berlin! They got pretty desperate towards the end of the war. (The Natter was an even more desperate Rocket Glider for Bomber defense.)
I'm not as familiar with the Japanese weapons, and tactics. Though such a cartoony/comic book stunt might be a little safer over the Pacific with recovery craft.
"Hail Hydra!"
The Nazis invented helicopters.
Sikorsky was Russian! That's a pretty neit prototype, though. Also, check out the
Triebflügel that Red Skull used to make his escape! A ramjet powered tail sitting auto-gyro!
