The supertanks were silly but could be built. But what about the crazy stuff like the suborbital bomber? Suppose Germany had the USA's resources and willing to pour it in like with the Manhattan Project. Could a working suborbital bomber be made?
There still isn't a working suborbital bomber, so I would say that no one could have developed one during the 1940's. Consider how long it took to get people into low earth orbit, and that was with small capsules.
Did the destruction of the Third Reich remove a scientific establishment that was decades ahead of the rest of the world? Or look at the USA; are the ethnic German people here any less capable than the ethnic Germans in Germany?
Thinking about jets, I'm coming to the opinion that no one's jet aircraft in WW-II were that capable. Jet technology was in its infancy. If the war had lasted into 1946-47, it would be different, especially for the side that was doing better.
Hmm, anyone know how long the P-80A's were in service? I'm thinking it was the -C model that fought in Korea.
