The SAI 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. [50] The supersonic Tupolev Tu-444 or Gulfstream X-54 have also been proposed.
The Boeing Sonic Cruiser was a concept jet airliner with a delta wing – canard configuration. It was distinguished from conventional airliners by its delta wing and high- subsonic cruising speed of up to Mach 0.98. Boeing first proposed it in 2001, but airlines generally preferred lower operating costs over higher speed.
Cancelled in 1971. The Boeing 2707 was an American supersonic passenger airliner project during the 1960s. After winning a competition for a government-funded contract to build an American supersonic airliner, Boeing began development at its facilities in Seattle, Washington. The design emerged as a large aircraft with seating for 250 to 300 ...
The first aircraft to fly supersonic in level flight was the American Bell X-1 experimental plane which was powered by a 6,000-pound (2,700 kg) thrust rocket powered by liquid oxygen and ethyl alcohol. Most supersonic aircraft have been military or experimental aircraft. Aviation research during World War II led to the creation of the first ...
The Whitcomb area rule, named after NACA engineer Richard Whitcomb and also called the transonic area rule, is a design procedure used to reduce an aircraft 's drag at transonic speeds which occur between about Mach 0.75 and 1.2. For supersonic speeds a different procedure called the supersonic area rule, developed by NACA aerodynamicist Robert ...
A sonic boom is a shock-wave, or pressure disturbance, caused by the movement of the plane through the air, much like the wave produced by the bow of a ship as it moves through water: just as the bow wave is produced for the entire journey of the ship, so the sonic shockwave occurs throughout the duration of a supersonic flight.

Deltasonic. Deltasonic is a British record label based in Liverpool, England. Previously joint ventured with Sony Music, it is now totally independent. It was formed by Alan Wills, the former drummer with Liverpool bands Shack and Top, and associated with the ' cosmic Scouse ' and 'scallydelica' music scenes. [1] [2] [3]
The problems at Delta are similar to the problems that occurred at Southwest Airlines over the end-of-year holiday travel period in 2022 when it had to cancel nearly 17,000 flights over the course ...
