New York, Sep 26: The US space agency National Aeronautics and Space Administration (NASA) has unveiled a supersonic passenger jet ‘Concorde’ which will take passengers between London and New York in just three hours. Concorde flies at a speed of 3,506 kilometres per hour (kmph) and can break the 1,234 kmph sound barrier. “We’re now one step closer to building an actual X-plane,” said a NASA official.

NASA has revealed images of its Quiet Supersonic Technology (QueSST) and the latest tests conducted by it. The Concorde has been developed with €330million. It is currently been tested in wind tunnels. The test flights could begin as early as 2021, the report said. The developers recently tested the prototype inside a massive wind tunnel at NASA’s Langley Research Center.

The current passenger jets take nearly eight hours and the QueSST is likely to bring that down to almost three. The new Concorde will be quieter than the previous one which gave off much noise when after reaching the speed of sound. After 34 years of service, it retired in 2003.

About the new Concorde, Nasa spokesman Peter Coen said, “Supersonic flight offers the potential to improve the quality of life of those that fly, by greatly reducing travel time. In the nearer term, NASA’s development of quiet supersonic flight technology needs support, interest, and engagement from the community to ensure that the potential sound is acceptable to those on the ground.”
