To fly at supersonic (faster-than-sound) speeds, an aircraft must break the sound barrier, defined as Mach 1, a speed that varies according to conditions of temperature and humidity. The Spike Aerospace S-512 is designed to fly from London to New York in 3 hours. The S-512, developed in 2013, has been recently upgraded with a modified delta wing to increase fuel efficiency and reduce sonic boom.
