Supersonic Jet Could Fly NYC To London In 3 Hours

An anonymous reader writes: A new supersonic luxury plane that could fly people from New York to London in just three hours is being developed by a team of engineers. Spike Aerospace's S-512 Supersonic Jet was introduced in 2013, but the company recently announced a few updates to the plane's design. Discovery reports: "Spike Aerospace's engineers claim the S-512 could reach a maximum speed of Mach 1.8 (1,370 mph, or 2,205 km/h), which is 1.8 times the speed of sound. For comparison, the fastest Boeing 747 commercial "jumbo jet" can reach a maximum speed of Mach 0.92 (700 mph, or 1,126 km/h). If the S-512 really is built to reach these supersonic speeds, it would be as fast as an F-18 Hornet, a military fighter jet with a max speed of Mach 1.8. This would also make the supersonic jet about 450 mph (724 km/h) faster than the fastest civilian jet, according to Spike Aerospace."
