From Ananova news: Weather troubles Concorde
Concorde was forced to take an unconventional route on its way to New York as it became the latest victim of Britain's soaring temperatures.
The British Airways flight had to stop in Gander, Canada, to refuel because the heat meant the jet needed to carry more fuel to make the journey.
The aircraft, which flies at twice the speed of sound, usually takes just three hours and 20 minutes to make the transatlantic crossing.
But today's detour was expected to add up to 90 minutes to the flight, which took off from Heathrow at 5.30pm.
A British Airways spokesman said: "When it gets this hot, Concorde has to carry more fuel because the air it is travelling through is of a higher pressure.
"It is unusual, but this certainly is not the first time it has happened because of the hot weather.
"The flight will stop in Canada for less than an hour and we expect it to land at about 5.30pm local time."
He said all the passengers had been informed of the flight's reroute before take-off.
