World’s Fastest Man Remembered

The world’s fastest man has left this earth for the last time. William J. “Pete” Knight became the world’s fastest man on October 3, 1967, while flying the X-15 hypersonic rocket plane. He died of cancer on May 7. His record-breaking Mach 6.7 (nearly seven times the speed of sound) flight remains the highest speed ever attained by a manned aircraft.
