Boom Supersonic’s XB-1 aircraft climbed over 35,000ft on Tuesday before accelerating to Mach 1.1 speed and then breaking the sound barrier in three high-speed runs spanning 35 minutes over the ...
Concorde (left) and Tu-144 in Auto & Technik Museum Sinsheim Boeing 2707 3-view diagram Lockheed L-2000 mockup. Concorde was one of only two supersonic jetliner models to operate commercially; the other was the Soviet-built Tupolev Tu-144, which operated in the late 1970s.
The fastest speed the XB-1 had reached prior to the January 28 flight was Mach 0.95, just below the supersonic threshold of Mach 1, which it hit during its last test flight on January 10.
Overture, a larger and faster passenger-carrying version of the test jet, is planned to launch in 2029 with a top speed of Mach 1.7, Boom says. That's about twice the speed of current airliners.
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.
The Rolls-Royce/Snecma Olympus 593 was an Anglo-French turbojet with reheat, which powered the supersonic airliner Concorde.It was initially a joint project between Bristol Siddeley Engines Limited (BSEL) and Snecma, derived from the Bristol Siddeley Olympus 22R engine.

Similar to the DH.108, the twin-jet powered 1948-vintage Northrop X-4 was one of the series of postwar X-planes experimental aircraft developed in the United States after World War II to fly in research programs exploring the challenges of high-speed transonic flight and beyond. It had aerodynamic problems similar to those of the DH.108, but ...
