A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA. Concorde's last commercial flight was in October 2003, with a November 26, 2003 ferry flight being its last airborne operation. Following the permanent cessation of flying by Concorde, there are no remaining SSTs in commercial service. Several companies have each proposed a supersonic business jet, which may bring supersonic transport back again

A bullet fired from a gun is an example of an object that flies at supersonic speeds. Military fighter aircraft also fly this fast. The space shuttle orbiter flies at supersonic speeds during portions of its mission. An airplane called the Concorde was the most notable passenger airplane to travel at supersonic speeds.

Supersonic flights are so called because they travel faster than the speed of sound. To do this, the aircraft must break through the sound barrier, which requires an efficient aerodynamic design to reduce drag, and considerable thrust from powerful engines to overcome the turbulence caused by shock waves.

Sonic booms are one big disadvantage of the supersonic jet. As an aircraft approaches the speed of sound, pressure waves form in front and behind the plane. Think of a ship with both a bow wake and the wake that trails behind it. As the plane’s speed increases, the pressure waves can’t get out of each other’s way fast enough and they start piling up. At the sound barrier, the waves form into one large shockwave in front of and behind the plane, making the distinctive “boom boom” sound. Since the plane is flying faster than the sound, people on board don’t hear the boom, but everyone else in range sure does.
