Daily US Times: United Airlines has announced “return supersonic speeds to aviation” and plans to buy 15 new supersonic airliners and in the year 2029.

Supersonic passenger flights ended in 2003 when British Airways and Air France retired Concorde after fatal accident.

The new supersonic aircraft will be produced by a Denver-based company called Boom, which has yet to flight-test a supersonic jet.

The US airlines company’s deal is conditional on the new aircraft meeting safety standards.

When an aircraft travels faster than the speed of sound is called Supersonic flight is supersonic flight.

At an altitude of 60,000ft, that means flying faster than 660mph.

A typical passenger jet may cruise at about 560mph but Overture is expected to reach speeds of 1,122mph – also known as Mach 1.7.

Journey times on transatlantic routes such as London to New York can be cut in half at that speed.

Boom says Overture jet would be able to make the trip in 3.5 hours, shaving three hours off the flight.

Concorde, which enteredinto service in 1976, was even faster with a maximum speed of Mach 2.04 – about 1,350mph.

There are two major concerns with supersonic passenger travel: pollution and noise.

Travelling faster than the speed of sound causes a sonic boom, which can be heard on the ground as a loud thunderclap or explosion and it’s where the company Boom got its name.

The boom limits where the paggenger jets can fly. Typically the planes must lower their speed until they are out over the ocean, away from citizens who may be disturbed by the loud bang.
