What was the world's first supersonic airliner to fly commercially?
Supersonic transport JAXA, the Japan Aerospace eXploration Agency, undertook aerodynamic testing of a scale model of an airliner designed to carry 300 passengers at Mach 2 (Next Generation Supersonic Transport, "NEXST", then Zero Emission Hyper Sonic Transport). If pursued to commercial deployment, it would be expected to be in service around 2020–25. Supersonic Aerospace International's Quiet Supersonic Transport is a 12-passenger design from Lockheed Martin that is to cruise at Mach 1.6, and is to create a sonic boom only 1% as strong as that generated by Concorde. The supersonic Tupolev Tu-444 or Gulfstream X-54 have also been proposed. While conventional turbo
Supersonic speed Base. The crew were William Magruder (pilot), Paul Patten (copilot), Joseph Tomich (flight engineer), and Richard H. Edwards (flight test engineer). This was the first and only supersonic flight by a civilian airliner other than the Concorde or Tu-144. Supersonic speed Supersonic travel is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 344 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Speeds greater than five times the speed of sound
