The return of supersonic transatlantic passenger flights are on the horizon in the next few years.
The world's biggest airline yesterday announced a deal to buy a fleet of new high-tech jets dubbed the "son of Concorde".
American Airlines has agreed to purchase up to 20 Overture aircraft from Boom Supersonic, with an option to extend the order to 60.
United Airlines and Japan Airlines have also placed orders for the yet-to-launch jets.
This would lead to the return of supersonic transatlantic travel, following the retirement of Concorde by British Airways in 2003.
Boom says Overture will carry 65 to 80 passengers and travel twice as fast as most commercial aircraft, boasting a cruising speed of mach 1.7 - roughly 1,300mph.
This could reduce journey times between London and New York from six and a half hours to three and a half hours.
Supersonic travel
Derek Kerr, American's chief financial officer, said: "Looking to the future, supersonic travel will be an important part of our ability to deliver for our customers.
"We are excited about how Boom will shape the future of travel, both for our company and our customers."
Overture will have a range of 4,250 nautical miles. It is being designed to fly more than 600 routes around the world in as little as half the time.
"We are proud to share our vision of a more connected and sustainable world with American Airlines," said Blake Scholl, founder and CEO of Boom.
"We believe Overture can help American deepen its competitive advantage on network, loyalty and overall airline preference through the paradigm-changing benefits of cutting travel times in half."
The Telegraph reports that, in July, Boom revealed the final production design of Overture, which is slated to roll out in 2025 and carry its first passengers by 2029.
The order from American comes just weeks after Boom unveiled a separate deal with US defence contractor Northrop Grumman to develop a military version of Overture.
Last supersonic passenger jet
Boom's planes have been nicknamed "son of Concorde" after the last supersonic passenger jet developed jointly by the UK and France.
The Anglo-French project was shelved after a fatal crash at Charles de Gaulle airport in July 2000.
Demand for the flights also began to wane as City and Wall Street banks baulked at paying £7,000 a seat to ferry executives across the Atlantic at faster-than-sound speeds.
Supersonic travel is inefficient compared to subsonic flight because of the extra fuel needed for higher speeds.
But the Telegraph states it is a tough sell at a time when the industry is going to great lengths to lower emissions. Boom says it will use so-called sustainable aviation fuel to limit its carbon output.
