A Boeing 787-9 twin jet Dreamliner hit 801 mph during a Virgin Atlantic flight from Los Angeles to London. The normal top speed for the plane is 587 mph, but the jet stream was moving at 230 mph over Long Island on Monday. This natural phenomenon assisted the plane to the 801 mph top speed and shaved 48 minutes off the flight time. Pilot Peter James tweeted, "Almost 800 mph now never ever seen this kind of tailwind in my life as a commercial pilot !! (200 mph tailwind )" An LAX-JFK Delta flight overnight hit 678 mph at 39,000 feet over the Ohio Valley, while a 737 from Chicago to New York passed 700 mph at 8:43 Eastern this morning. Chicago to New York/Boston routes will be shortened to 1 hour, 24 minutes Wednesday instead of the usual nearly two-hour flight time. Likewise, flight times from Dallas to Boston dipped below three hours, with an Embraer ERJ-190 twin jet achieving 739 mph in the jet streak.
