This plane flies from London to New York in 80 minutes

A Spanish designer has unveiled a jaw-dropping design for a new supersonic plane that could get from London to New York in 80 minutes.

The idea uses a combination of theoretical cold fusion nuclear systems and innovative Mach 3.5 technology.

Mach is the ratio of the speed of a body to the speed of sound – Mach 1 is the speed of sound, Mach 2 is twice the speed of sound, and so on.

The plane would shoot through airspace at almost 2,500mph – almost five times the current average speed of commercial passenger planes that take up to eight hours to complete the journey from London to New York. If plans for the jet came to fruition, it would take just 80 minutes to complete the popular transatlantic route.

This would power two ramjet engines and four next gen hybrid…
