New York flight goes SUPERSONIC: BA jet gets to London in five hours 16 minutes after it hits 'powerhouse jet stream' which hurls it to 745mph

  • Boeing 777-200 hit top speed of 745mph on New York to Heathrow route
  • Flight time cut as powerhouse jet stream sweeps over the Atlantic 
  • Speed of sound at sea level is 761mph, Concorde hit 1,350mph 

A plane flying from New York to London Heathrow hit near supersonic speeds yesterday after getting caught up in a powerhouse jet stream.

British Airways Flight 114, a Boeing 777-200 jet, took off from JFK at 10.50pm Eastern Standard Time (EST), and landed at 9.06am local time at London Heathrow.

The total flight time was five hours and 16 minutes, well short of the estimated minimum six-hour journey.

The difference in temperature between the Equator and the North Pole means pressure and winds are greater thus reducing flight times between the US and the UK (jet stream in purple)

What's more, the flight was reported to have flown at speeds of 745mph relative to ground speed.

The speed of sound at sea level is 761mph.

Several flights are reported to have made the journey from New York to London yesterday in around five hours 20 minutes due to the 200mph North Atlantic jet stream.

It is not unexpected for the jet stream to intensify during the winter months, with flight times in January and February between the US and the UK shortening in duration.

The temperature contrast between the equator and the North Pole is at its greatest during these months, and as well as leading to polar-vortex related climate experienced by the US currently, air pressure and wind increases.

Sadly, however, the strength of the jet stream is heavily weighted in one direction; that is to say flights heading to the US from Europe will see an increase in duration.

The Atlantic jet stream route was taken advantage of by the Concorde, when in 1996 it hit a top speed of 1,350mph and took just two hours and 53 minutes from New York to London

Often this is because pilots are forced to fly closer to Greenland to escape powerful headwinds, as oppose to the direct route over the Atlantic.

Despite the Boeing 777-200 jet reaching a top speed of 745mph, it doesn't come close to matching the top speed of the Concorde on the same flight path.

Back in 1996, a New York to London flight took just two hours, 53 minutes, and hit top speeds of 1,350mph.
