Nasa's QueSST Passenger Jet will be the second supersonic passenger jet after the Concorde, which was retired in 2003, or the third if we include the Soviet Tupolev Tu-144 (1977), which was in commercial use for only seven months, which is a drop in sea compared to Concord's twenty-seven years of service. Since 2003, jet passenger planes have not been flying in the air, that is, planes that fly faster than sound, but thanks to the American space agency NASA, we are one step closer to the return of these steel birds. Namely, they unveiled the design for Concorde's successor, the QueSST Passenger Jet, a silent supersonic passenger jet, the first of NASA's upcoming new series of X-planes.
