A hi-tech new jet could reignite the age of supersonic travel - blasting from London to New York in just half an hour.
The ‘Skreemr’ concept aircraft could reach 10 times the speed of sound, according to designers Charles Bombardier and Ray Mattison.
The designers say that the aircraft - which has four wings and two large rockets - would be launched into the sky on a magnetic ‘railgun’.
Rockets would then propel the passenger craft to Mach 4 - four times the speed of sound - before hi-tech ‘scramjets’ blasted it up to Mach 10.
At top speed, the concept craft - which uses technologies in design for military craft, but is not slated to go into production - would hit 7,673mph.
It’s not the only hi-tech idea being mooted to bring back the age of supersonic travel.
Airbus patented a hi-tech craft which could travel from London to New York earlier this summer.
The hypersonic craft patented by the company would travel twice as fast as Concorde - flying at an altitude of 100,000 feet.
A patent describes a vehicle powered by three different types of engine - and capable of a vertical climb at take-off.
Twin turbo jets would help the jet to climb at take-off, retracting into the fuselage as the jet sped towards the sound barrier.
A rocket motor then takes the plane to an altitude of 100,000ft, where twin wing-mounted ramjets push it to its final speed of 4.5 times the speed of sound.
The jet is described as, ‘an air vehicle including a fuselage, a gothic delta wing distributed on either side of the fuselage, and a system of motors able to propel the air vehicle.'
