American Airlines passengers were forced to evacuate their plane after it caught on fire at Denver Airport on Thursday following mid-air engine trouble. 

Terrified passengers were seen fleeing via the wing of the aircraft as smoke billowed from the plane. 

The flight, AA 1006, had departed Colorado Springs Airport at 4:52pm (local time) and was headed to Dallas Fort Worth International Airport.

The Boeing 737-800 aircraft was diverted to Denver shortly after takeoff when the crew reported engine vibrations, according to Federal Aviation Administration.

'After landing and while taxiing to the gate an engine caught fire and passengers evacuated the aircraft using the slides,' said the FAA.
