Regarding Communist spies; has anyone read WWII pilot, Eddie Richenbacker’s account of how he, during WWII, observed US Lend Lease planes flying out of a military base in Great Falls, Montana, and headed for the USSR loaded with Uranium? Richenbacker was concerned enough to report what he saw to his superiors — it seems his comments fell on deaf ears. Kind of makes you wonder who the real spies are.
Richenbacker was a WW1 ace. He wrongly assumed that any radioactive materials were uranium. Plenty of other radioactive materials had military uses in 1940s.
