A jaw-dropping new supersonic plane could get from London to New York in 80 minutes. The Hyper Sting concept would travel at 2,486mph - almost twice that of Concorde.
Spanish designer Oscar Viñals says 170 passengers could enjoy travel at more than three times the speed of sound. He explains that a Mach 3.5 capability would be thanks to innovative systems like a so-far theoretical cold fusion nuclear reactor.
This would power two ramjet engines and four next gen hybrid turbojets. At 328ft, the Hyper Sting would be more than 100ft longer than Concorde, and have a wider wingspan of 169ft compared to Concorde's 85ft.
