However, exactly how big the effort is is still unclear. American, which said it was putting down a deposit for up to 20 supersonic jets with an option to buy up to 20 more, declined to share the financial terms of the deal, which was announced Tuesday.
Boom is developing a jet called the Overture that the company says will be able to carry 65 to 80 passengers at nearly twice the speed of sound.
But the jet is still in the early stages of development. Boom recently unveiled a “refined”[ads1]; version of the aircraft, which it said has completed some wind tunnel tests. However, it has yet to conduct a test flight, and the first production vehicles are not expected to roll off the line until 2025, according to a press release.
Boom says its jets could be operational by 2029, and while they won’t be able to reach top speeds over land, they can still travel as much as 20% faster than current commercial jets, the company claims.
– Flying from Miami to London in just under five hours and Los Angeles to Honolulu in three hours are among the many possibilities, claims Boom.
But foreign regulators and the US Federal Aviation Administration, which regulates commercial airlines, must approve the jets first. And it is not clear when or if that will happen.
After the financial failure of Concorde, both airlines and aircraft manufacturers have generally concentrated on greater efficiency, not speed.
