A plane taking off from New Delhi’s main airport caught fire forcing all 252 passengers and crew to escape through an emergency exit, said airport officials on Friday.

The Air Mauritius pilot apparently braked suddenly as the plane prepared to takeoff, and this might have sparked a fire that spread to the jetliner’s undercarriage, said Indira Gandhi International Airport spokesman Arun Arora.

Rescue workers and firefighters rushed to evacuate the plane and put out the blaze Thursday afternoon. All 241 passengers and 11 crew on the New Delhi to Mauritius flight escaped safely through emergency exit, although there was some panic.

Local media reported the accident was caused by a bird that hit the plane, but Arora could not confirm that and said the incident was under investigation.
