SR-71A 64-17960 performed in front of a vast, appreciative audience in May 1986 at the annual Mildenhall Air Fete. During its final pass, the aircraft suffered a momentary double flame out, resulting in unburnt fuel entering the rear of the engine, which then combusted when they were relit. The result was a huge fireball which held in the Suffolk sky for a few seconds. Copyright Bob Archer 2006
