von braun became us citizen on april 15, 1955
Jet engines can be dated back to the first century AD, when Hero of Alexandria invented the aeolipile. This used steam power directed through two jet nozzles...
....He 178 airframe and flown by Erich Warsitz in the early morning of August 27, 1939, from Marienehe aerodrome, an impressively short time for development. The He 178 was the world's first jet plane.
Meanwhile, Whittle's engine was starting to look useful, and his Power Jets Ltd. started receiving Air Ministry money. In 1941 a flyable version of the engine called the W.1, capable of 1000 lbf (4 kN) of thrust, was fitted to the Gloster E28/39 airframe specially built for it, and first flew on May 15, 1941 at RAF Cranwell.
i guess i didnt say they were coppying/using german stuff,
if memory serves, i said:
"nearly all their weaponry (exept GPS and laser) is just modification on german stuff, and initially made by germans, werner fon braun comes to mind",
modification like aim9 sidewinder etc etc and so forth.
and yes, i didnt mention nuclear weapons, the intention
was not to point out every little piece of weaponry, but rather to point out
that ussr isnt the only one imitating, as skywalker was so indignant over.
when you said 45-46, i interpreted it like all the german stuff and german engineers etc had played out their role in history, and that none of todays technologies has their roots in nazi technology, i guess i interpreted wrong.
you wrote the only breakthrough was ballistic missiles.
i consider a2a missiles was a breakthrough in a2a battles,
otherwise they'd still be doin biggles-baron gun dogfights.
same goes for naval warfare, no missiles, only guns and torpedoes.
and so forth...
