The wind accelerated the aircraft to the speed of sound

It turns out that to accelerate to the speed of sound, a passenger plane does not have to be a Concorde or Tu-144. As it turned out, this trick can be done by the usual Boeing 787–9 Dreamliner - however, under a certain set of circumstances. On February 18, a Virgin Airlines British airliner operated a regular flight from Los Angeles to London and landed in the so-called high-altitude jet stream over the state of Pennsylvania.

This is the name of the relatively narrow zone of strong wind in the upper troposphere, which is characterized by extremely high wind speeds. Actually, a fair wind also helped the aircraft accelerate to an incredible speed of 1285 km / h - faster than the speed of sound, which at an altitude of 11 kilometers is 1062 km / h. The usual speed of the Boeing 787−9 at this altitude is 902 km / h, which is noticeably (383 km / h!) Slower.

Thanks to traveling at supersonic speeds, passengers arrived in the UK 48 minutes ahead of schedule. A 25-year-old pilot, Peter James, on his Twitter, captured the record speed of an airliner and noted that he had never seen such a fair wind in his entire career as a commercial airline pilot:

Almost 800 mph now never ever seen this kind of tailwind in my life as a commercial pilot !! (200 mph tailwind) pic.twitter.com/0XGTkEP9EB
