5 Supersonic Passenger Aircraft: Canceled, Completed & Planned

A supersonic aircraft can fly at a speed greater than sound speed (Mach 1). As of 2024, only two supersonic commercial aircraft have been put into service and both have retired (Concorde and the Tupolev Tu-144 – the Soviet's flawed Concorde challenger). Safety and issues surrounding the sonic boom have made creating commercially viable supersonic airliners difficult. However, more supersonic aircraft are in development now (with Boom leading the charge).
