With Mach 1 and Mach 2 behind them, NACA engineers sought to expand on their research to fully understand the problems associated with flying at supersonic speeds. The next milestone was Mach 3, and the rocket powered Bell X-2 Starbuster hit that mark on Sept 27, 1956. Unfortunately there was a problem as the aircraft turned back toward Edwards Air Force Base and began tumbling out of control. The pilot, Capt. Milburn "Mel" Apt, did not survive.
