Thai Lion Air will investigate an incident on Friday when the engine of one of its planes caught fire after taking off from Don Mueang International Airport.
A source on Friday said the aircraft took off from the airport at 11.10am, but crew and passengers noticed audible shuddering once it reached an altitude of 6,000 feet.
A passenger told a cabin crew member that she saw sparks fly from the engine under the right wing, which prompted the pilot to shut it down and head back to the airport where the plane landed safely at 12.05 pm.
Some passengers fainted and vomited during the incident. No injuries were reported. Despite their ordeal, the passengers praised the captain for his safe landing.
