I wanted to know if Goddard and vonBraun knew each other, and yes, they were friends.

Robert Goddard is about as clear an example of the scriptural snippet as you can get - A prophet is not without honor, except in his own country, among his relatives, and in his own household. If Uncle Sugar had funded him, the US would have had ballistic missiles long before Germany. Of course, a missile program would have been a huge load for an already underfunded defense budget (1% of GDP) to carry.
Goddard an Billy Mitchell are the fathers of modern warfare. The ballistic missile (Goddard), strategic bombing and the aircraft carrier (Mitchell) collectively obliterated the safety and security of international borders.
You try that today and the FBI will be swarming all over you/
Tonight as a result of your post, I ended up reading Goddard's Wikipedia page and learned much more about him that I hadn't known previously. It really made my evening! :-)
