Aerospace company Boeing has unveiled a new jet that could fly from New York to London in just two hours. The new plane, which could be flying passengers as early as 2030, is two-and-a-half times faster than the now-retired supersonic Concorde jets. It would make it possible for people to fly between the US and the UK for a day trip. The flight takes just over six hours to fly the 5500km one way on regular passenger jets now. The concept plane made to show a plane still being designed was unveiled at the American Institute of Aeronautics and Astronautics Aviation 2018 conference in Atlanta, US. It would fly at 6437kmh, which makes it a hypersonic jet. Supersonic means faster than the speed sound travels at. Hypersonic means travel at five times the speed of sound. This is also sometimes called Mach 5. The plane would fly extremely high almost 30km up in the sky. Concordes flew about 18km high. The Wright brothers’ 1903 flight is considered the world’s first of a heavier-than-air, powered, steered the plane. The world’s first passenger flight took off from St Petersburg, Russia and flew to Tampa, Florida, US, on January 1, 1914.
