Passengers escaped from an American Airlines plane down an emergency slide at Heathrow Airport following a “technical issue”.
Footage showed passengers, including children, disembarking via a slide towards the runway at the rear of the aircraft at Terminal 3, The Press Association reported.
Airport fire crews were dispatched to the aircraft, but no-one appeared to be injured during the alert on Sunday morning, according to an eye-witness.
He said: “I saw a lot of smoke come out from the tail-end of the aircraft. I wondered if it was normal, whether it was just exhaust fumes.
“Then the door opened on the right side of the aircraft and crews deployed slides from the rear and the middle of the plane.
“It all happened in a matter of seconds. Everyone seemed to be okay.”
A Heathrow Airport spokeswoman said a “technical issue” was identified with the aircraft and the problem was resolved.
