Brig. Gen. "Chuck" Yeager pushes his F-15D fighter through the sound barrier high above Edwards Air Force Base in the Mojave desert. The date is 14th. October 1997, 50 years to the day since Yeager became the first man to fly faster than the speed of sound, in the Bell X-1. The 'ghost' of the X-1 sits on Yeager's wing for his last military flight.
