A powerful jet is helping flights from the North America to Europe.
Since few days, transatlantic flights take benefit of a strong jet stream.
The aircraft sometimes reach a ground speed over 700 kts (over 1300 km/h).
For exemple, the Virgin Atlantic #VS26 reached London Heathrow from New York JFK in less than 5 hours and 45 minutes.
The fastest transatlantic crossing from west to east, New York to London, was made by Concorde in 2 hours 56 minutes on 1 January 1983.
