The worldâs first ever supersonic aircraft having a top speed of Mach 2.35 or 1,550 mph. it is the fastest commercial airliner the world ever have. However, it has not been that of successful. In 1978, the jet retired from service.
The speed of sound is not a constant, but depends on altitude (or actually the temperature at that altitude). A plane flying Mach 1.0 at sea level is flying about 1225 km/h (661 Knots, 761 mph), a plane flying Mach 1.0 at 30000 ft is flying 1091 km/h (589 knots, 678 mph) etc. Speeds below Mach 1 are called subsonic, between Mach 0.8-1.2 Transonic and above Mach 1.2 Supersonic.
