This black Lockheed L-100-20 flew first on 19 June 1984 and was the High Technology Test Bed (HTTB) of manufacturer Lockheed. The Hercules was used for test and demonstration of advanced concepts for future C-130 design and developments. The aircraft was sadly lost in a crash at Dobbins AFB (GA) on 3 February 1993, killing the crew of seven. The cause of the crash was possibly a disengagement of the rudder fly-by-wire flight control system which resulted in a total loss of rudder control capability while conducting ground minimum control speed tests.
