The SST (Supersonic Transport) concept was primarily developed in the mid-20th century, with significant advancements occurring during the 1950s and 1960s. The most notable SST aircraft, the Concorde, was introduced in the 1960s, with its first flight in 1969 and commercial service beginning in 1976. The Soviet counterpart, the Tupolev Tu-144, also made its first flight in 1968. Both aircraft embodied the SST concept of flying faster than the speed of sound for commercial aviation.
