Terrified plane passengers heard their jet's engine explode just moments before take off.
The Thai Airways Boeing 777 was taxiing towards the runway, with 339 people on board, when travellers heard the loud bang.
The Zurich-bound flight was due to take off at 1.05am from Bangkok's Suvarnabhumi Airport on Sunday.
But the pilot aborted the scheduled departure and headed back to the terminal.
Pictures taken by one passenger, who wished to remain anonymous, show a large crack along the engine casing.
They said: "We didn't take off on this flight as there was a loud explosion.
"The plane was getting ready to take off then we heard 'boom' and a very loud sound.
"It all happened in a fraction of a second.
"The machine was immediately turned off and the hostess gave us instructions to leave. I was shocked and then told me about it a little more."
Passengers were given a hotel and the flight, TG 970, was reschedule to depart at 1pm the same day.
Thai Airways said in a statement that the Boeing 777-300ER had been taken out of service to be repaired.
"All passengers and crew were provided a hotel, which is a standard for taking care of passengers," it read.
"The reschedule flight arrived in Zurich Airport at 19.45."
