Was that the incident many years ago where the mig pilot defected. I thought I remember we tested the aircraft before giving it back?With over 11,000 of them built, it was important for the USAF to know what they were up against. Some Mig-21 copies were somehow 'acquired' and thoroughly tested by American test pilots.
