The typical speed of Boeing 777-300ER on the way from Warsaw to New York is 916 km/h (569 mph). On its way back it reaches 1140 km/h (708 mph). How is it possible?
it flies at higher altitude
jet stream helps
air convection helps
plane is lighter on way back
The location of the jet stream is extremely important for aviation. Commercial use of the jet stream began on 18 November 1952, when Pan Am flew from Tokyo to Honolulu at an altitude of 7,600 metres, cutting the trip time by over one-third.
