London-Sydney in five hours?

London to Sydney could be possible in just five hours and London to New York in two hours, if plans by Virgin Galactic go ahead.

Don’t get too excited – it’s still in the very early stages – but this week Virgin Galactic and engine-maker Rolls-Royce revealed they are working on designs, with help from NASA, for a supersonic passenger plane capable of flying with a top speed of around 2,300mph, or three times the speed of sound.

The delta-wing jet would cruise at a 60,000ft, higher than current passenger planes, and would accommodate nine to 19 passengers in custom cabin layouts with Business or First Class seating arrangements.

The announcement said the Mach-3 jet would fly long-distance commercial routes, using existing airports, and that U.S. aviation regulator the FAA has agreed to help develop a certification framework for the plane.

George Whitesides, Chief Space Officer for Virgin Galactic, said: “We have made great progress so far, and we look forward to opening up a new frontier in high speed travel.”

Supersonic flying ceased to exist when Concorde retired 17 years ago but others are also working on projects, including aerospace giant Lockheed-Martin and US start-up Boom Supersonic, which plans to reveal a prototype this winter followed by test flights in 2021.
