Ironically for the US WWII was quite lucrative in the arms and equipment it sold, Marshal plan and space development with the help of German rocket designers
we finally paid back the loans for US and Canada in 2006
Space development with the German's help...lol.
The U.S didn't have a space program...it captured a German one.
Project Paperclip.
It's guesstimated the U.S got half of Germany's top scientists, while Russia got the rest.
The U.S also got Werner Von Braun, inventor of the V2 Rocket, and a Space Station, among other things.
More interestingly, here's a genious when asked how they came up with these things, his answer is "we had help from people from other worlds".
Strange response when he could have simply taken the credit.
Alot of amazing tech came of of Germany.
Ever seen the single seat, wooden, stealth fighter jet, and yes, it is invisible to radar.
2 were known to exhist and be recovered by the Allied Forces.
One is who knows where...the other...in the Smithsonian...Not on display!
Secrets are better when you don't talk about them.
But, when you realize the tech of 80 years ago, it really makes you think about what's really available today.
