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. Supersonic airliners have been the objects of numerous recent and ongoing design studies.

Why did the SST stop flying?

Of course, the crash didn't help (Concorde flights were grounded for a year, pending modifications), but the main reason behind Concordes no longer taking flight is simple: a general downturn in the economic industry, especially following the September 11 terrorist attacks.

When did the SST stop flying?

The supersonic Concorde jet makes its last commercial passenger flight, traveling at twice the speed of sound from New York City's John F. Kennedy International Airport to London's Heathrow Airport on October 24, 2003.
