Virgin flight hits record 801 mph due to powerful jet stream

A powerful jet stream propelled a commercial airline flight to record speeds of more than 800 mph. Virgin Atlantic Flight 8, a Boeing 787, from Los Angeles to London reached a top speed of 801 mph as it travelled through the high-altitude air current while flying about 35,000 feet above Pennsylvania Monday. The flight's record speed took place in the midst of a jet stream that was recorded at more than 230 mph over Long Island. It appears that’s a record for the Boeing 787-9 twin jet, which in the past has flown at speeds up to 776 mph. The ordinary cruising speed of a Dreamliner is 561 mph, with a maximum propulsion of 587 mph. <br/>
