Passengers film from inside Singapore Airlines flight as plane burns

What's remarkable from the footage is that passengers seemed to be quite calm.
A Singapore Airlines flight, on its way to Milan, turned back to Singapore on Monday, two hours into its flight.
Passengers said the pilot announced that there was an engine problem, according to the Guardian.
The airline said on Twitter that the issue was "an engine oil warning message."
The plane, with 222 passengers and 19 crew on board, executed an emergency landing at Singapore's Changi airport. After the plane touched down, however, the right engine of the Boeing 777-300ER caught fire.
Passengers had to sit inside the plane while emergency crews put out the fire.
