The World's first supersonic aircraft. A Bell X-1 aircraft in flight. The X-1 was the first aircraft to fly faster than sound. This historic flight took place on 14 October 1947, piloted by Captain (later General) Charles 'Chuck' Yeager. The X-1 was carried into the air under a converted B-29 bomber. At an altitude of 6800 metres, the X-1 was released. Powered by a four-chamber XLR-11 rocket engine of kilonewton (kN) thrust, the X-1 achieved a speed of 1078 km/h at an altitude of 12,800 metres - equivalent to times the speed of sound. The aircarft was unofficially named \Glamorous Glennis\" after Yeager's wife. It is now on display in a museum in Washington."
