A supersonic transport (SST) is a civil aircraft designed to transport passengers at speeds greater than the speed of sound. The only supersonic civilian aircraft to see service were the Soviet produced Tupolev Tu-144 which first flew in 1968 and last transported passengers in 1978, with NASA retiring it from any use in 1997; and the Franco ...

Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level , this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h).
Mach 2.02 (~2,154 km/h or 1,338 mph) cruising speed [73] for optimum fuel consumption (supersonic drag minimum and turbojet engines are more efficient at higher speed); [74] fuel consumption at Mach 2 (2,120 km/h; 1,320 mph) and at altitude of 60,000 feet (18,000 m) was 4,800 US gallons per hour (18,000 L/h).
NASA used the pre-production XB-70 triple-sonic bomber prototype for high-speed research in the. 1960s. ... wingtips that remained horizontal at subsonic speeds, but folded down once supersonic to ...
Jet engines, as a class, can supply increased fuel efficiency at supersonic speeds, even though their specific fuel consumption is greater at higher speeds. Because their speed over the ground is greater, this decrease in efficiency is less than proportional to speed until well above Mach 2, and the consumption per unit distance is lower.
Manned by Boom Supersonic's chief test pilot Tristan "Geppetto" Brandenburg, the XB-1 launched in the early hours of Tuesday, reaching an altitude of 35,290 feet and accelerating to speed Mach 1. ...
Two days later, AV-2 crashed following a mid-air collision with an F-104 while flying in a multi-aircraft formation. [96] Sonic boom and later testing continued with XB-70A #1. [97] The second flight research program (NASA NAS4-1174) investigated "control of structural dynamics" from 25 April 1967 through the XB-70's last flight in 1969.
