A jet stream helps a flight to reach 801 mph because of the jet stream: reports

A Virgin Atlantic flight from Los Angeles to London reached ground speed of 801 mph with the help of high winds, according to reports.

The blazing speed was reached 35,000 feet above Pennsylvania. A furious jet, the high-altitude airflow along which thunderstorms spread, gave the Boeing 787 a boost.

"[N]Never seen this kind of downwind in my professional pilot life, "tweeted Peter James, a jet skipper.

Monday's record was above the speed of sound – which is 767 mph – however, the fact that air transport breaks the sound barrier depends on the speed of the air, and not the speed at which ground. Commercial aircraft are not designed to fly at supersonic speeds.

The Virgin Atlantic flight arrived in London 48 minutes earlier. The Boeing 787 airliner has already reached a top speed of 776 mph and a cruising speed of about 561 mph, the Washington Post reported.


Several other high speeds were recorded Monday. A Los Angeles-New York City flight reached 678 mph at 39,000 feet over Ohio, while 737 planes en route from Chicago to New York surpassed 700 mph on Tuesday morning.

The jet stream was so powerful that the Dallas-Boston flight time was less than three hours.
