The jet stream is pushing passenger planes traveling east from the US across the Atlantic Ocean to speeds nearing 780 mph, above the speed of sound.

Commercial supersonic flight sped closer to returning as the Boom Supersonic XB-1 prototype reached a transonic speed of Mach 0.95 during Test Flight 11 on January 10, 2025, in the skies over the ...

Whoosh! Transatlantic flight reaches peak speed near 840 mph but doesn’t break sound barrier A commercial flight from Newark to Lisbon reached its destination an hour ahead of its normal flight ...

XB-1 demonstrator did not quite break the sound barrier during its seventh test flight but reached speed and altitude milestones.

Not your typical ‘supersonic’ flight Aircraft flying the speed of sound is, of course, nothing new. Chuck Yeager first reached Mach 1 in 1947.

Boom Supersonic has passed another milestone in developing the supersonic jetliner it plans to build: Federal go-ahead to exceed the speed of sound during flight tests in southern California.

China has made significant progress in hypersonic aviation, announcing the successful test flight of a jumbo jet prototype that achieved speeds of Mach 6.56, or approximately 5,033 miles per hour ...

A massive jet stream formed over the mid-Atlantic region this past weekend, pushing eastbound planes faster than the speed of sound.

More to the point, scientists and engineers are developing a method of supersonic flight that aims to both allow aircraft to travel at four times the speed of sound and reduce the impact of the ...
