European aircraft maker Airbus will fly from London to Tokyo in flat two hours! It will take only two hours to fly from London to Tokyo and be virtually pollution free,

But it will take 40 years before commercial operations begin, the Daily Mail reports.

Plans were unveiled on Sunday for the first hypersonic passenger jet, which would use three sets of engines to reach 3,125mph, more than four times the speed of sound, known as Mach 4, reports say.

This plane is hailed as a heir apparent for Concorde, which stopped services two years ago.

'It is not a Concorde but it looks like a Concorde, showing that aerodynamics of the 1960s were already very smart. The plane would fly just above the atmosphere, meaning it could fly at more than 3,000mph. When you are above the atmosphere nobody hears anything. We've been working on this project for long enough now to know it is viable, said Jean Botti, innovation and technology director at EADS

Once at a suitable height, the pilot would engage a pair of rocket engines which would propel the aircraft to much higher speeds and soar above the atmosphere, allowing a final set of engines known as ramjets to be utilized, the report said.

Currently used in missiles, these are highly efficient at speeds above 1,000mph, but cannot work from a standing start. They will help take the plane up to altitudes of 20 miles as it cruises at speeds beyond Mach 4. Cruising altitude for conventional passenger jets is around six miles, Mail reported.
