United Airlines to fly supersonic passengers at end of decade

Since 2003 and the last Concorde flight, there have been no commercial flights of supersonic planes. United Airlines intends to take back the collar with the help of the manufacturer Boom: the airline company announced the purchase of 15 planes exceeding the speed of sound.

United Airlines wants to deliver the supersonic experience to its wealthy passengers. The airline company announced this week the acquisition of 15 supersonic planes produced by Boom, with an option to mount up to 50 planes. Boom expects its planes to be able to carry their first passengers in 2029.

Up to Mach 1.7

The promise is exciting: these devices with a capacity of 88 people will make it possible to travel between New York and London in three and a half hours, compared to seven hours currently. Or link Los Angeles to Sydney (a trip that normally lasts about fifteen hours) in just six hours and 45 minutes! All of this will come at a price: the seat fare will be $ 5,000, according to Boom (United have not confirmed the price).

But Boom still has everything to prove. The first tests were to start in 2017 with the first passengers transported from 2020. The manufacturer is now a decade behind its initial schedule. The next step for the company is to carry out a test: the XB-1 is a 21-meter-long scale model, only capable of carrying the pilot, and which should take off this year.

This prototype will be able to fly up to Mach 1.3, while the final version of the aircraft, 62 meters long, will have to fly up to Mach 1.7 at a height of 18,000 meters. The supersonic aircraft will produce no CO2 emissions, also promise the two partners, thanks to the use of 100% sustainable fuels. On the other hand, neither Boom nor United specify the type of fuel, nor how they intend to achieve carbon neutrality.

In short, there are still many questions surrounding this agreement. Since 2003 and the last Concorde flight, the supersonic has not succeeded in making a comeback in the aviation sector, due to its cost, pollution and… the “boom” produced when the aircraft reaches speed. his.
