'Son of Concorde' supersonic jet crushes speed test, company reports

Summary

84% Informative

Supersonic test plane XB-1 smashed its top speed record Tuesday at Mach 0.82 or 499 knots ( 575 miles per hour ) true air speed.

The milestone marks the closest that Boom Technology's supersonic demonstrator aircraft has come to traveling faster than the speed of sound, Mach 1.7 .

Boom's project has been likened to the famous Concorde passenger jets of the 20th Century , which flew over the Atlantic at speeds of Mach 2 from 1973 to 2003 .

The company has vowed in 2017 that its NYC to London flights will cost about $5,000 per customer, compared to Concorde 's old seats.

These include sculpted, swept-back wings set far back on the craft; a tail that creates lift; and an engine that is mounted high up on the plane, above the wings.

But for now: 'The X-59 is just a tech demonstrator that is not going to leave US airspace'.
