NEW YORK CITY, N.Y. - On Monday night, the river of air 35,000 feet above the New York City area, known as the jet stream, clocked in at a blazing 231 mph.

The 787 Dreamliner generally cruises at 561 mph, but went faster than the speed of sound - but not the sound barrier - because of the relative speed of the air around the jet. The record-breaking flight was made possible thanks to warm El Niño waters in the Pacific and strong winds coming from the west combining with a polar vortex.
