Microsoft's Fly!

The aircraft of Virgin Atlantic airlines, flying from Los Angeles to London, during the flight exceeded the speed of sound. 

It is noted that at an altitude of about 11 kilometers, the Boeing 787-9 Dreamliner got into a high-altitude jet stream, due to which it was able to develop a speed of 800 miles per hour (1285 kilometers per hour), while at this altitude the speed of sound is 1062 kilometers per hour, and the usual speed of such an airliner is 561 miles per hour (902 kilometers per hour).
However, despite this acceleration, the plane arrived in London only 48 minutes ahead of schedule.
Later, the pilot of the aircraft Peter James wrote on Twitter that never in his 25-year career has not met such a fair wind.
