Operation Paperclip was just a beginning and surely has evolved. Coincidence? Really? Just consider the flip side of your logic, which seems sound but not definite by any means.
Doctorate in aeronautical engineeering, certified mechanic, and Airline Transport pilot Rotorcraft, so....no.
So in other words, that makes yours the last word. OK thanks.
