The promise of travelling from New York to London in less than 60 minutes, or Los Angeles to Tokyo in three hours, has been around since 1949, when an unmanned two-stage Bumper rocket blasted through the sky at 5,150 mph. About 12 years later, the U.S. Air Force’s X-15 became the first piloted aircraft to achieve hypersonic flight, generally defined as reaching a minimum of Mach 5 (five times faster than the speed of sound) or 3,800 mph.

Sierra Space and Radian have developed spaceplanes that reach almost 18,000 mph for entering orbit and visiting private space stations. They’re not just not sci-fi. They’re here. If Mach 1+ sounds too slow for that transatlantic flight, how about Mach 22.5, or 17,400 mph? That may soon be an option, thanks to a fleet of spaceplanes readying to take flight.

If Mach 1+ sounds too slow for that transatlantic flight, how about Mach 22.5, or 17,400 mph? That may soon be an option, thanks to a fleet of spaceplanes readying to take flight. While the latest generation of both supersonic and hypersonic aircraft mostly use jet engines and atmospheric oxygen for combustion, spaceplanes, generally speaking, also have wings but use rocket engines and carry O2 on board.
