US airline ‘United’ has announced plans to buy 15 new supersonic airliners and return to supersonic speeds to aviation in the year 2029.
Supersonic passenger flights ended in 2003 when Air France and British Airways retired Concorde.
The new ‘Overture’ aircraft will be produced by a Denver-based company called Boom, which has yet to flight-test a supersonic jet.
United’s deal is conditional on the new aircraft meeting safety standards.
Supersonic flight is when an aircraft travels faster than the speed of sound. A typical passenger jet may cruise at about 900 kilometres per hour, but Overture is expected to reach speeds of 1,805 kilometres per hour.
