 Rumors of B-29s existing at Aberdeen Proving Grounds revealed several airframes, but due to the closeness of ocean air these aircraft were corroded close to the point of unrestorability.Then, in 1970, came the discovery of the US Navy fleet of aircraft at Naval Air Weapons Station China Lake – these aircraft being used/stored in the desert air were in much better shape.After a year of negotiation, the CAF was able to obtain their B-29 ("Fifi").
