At least 30 passengers of a Chennai-bound Jet Airways flight were injured during evacuation by emergency chutes in Mumbai last night. A Mumbai International Airport spokesperson said that 15 persons were taken to Nanavati hospital in ambulances for further treatment after receiving first aid at the airport. A Jet Airways official said that nine passengers have been admitted to the hospital. The airport spokesman said, the commander onboard Jet Airways flight 9W 2302 ordered emergency evacuation after he was informed about an indication of an engine fire. Panic gripped 153 passengers on-board the Mumbai-Chennai flight after a fire alarm in the cockpit went off when the plane was on the taxiway for takeoff. As there was a sudden surge of passengers when they were being evacuated using chutes, 30 of them received injuries. There were some reports that a few passengers jumped from the aircraft and sustained injuries while there was a chaos when passengers rushed to slide down the chutes. A full emergency was declared at the Mumbai Airport and Fire Tenders were rushed immediately to the spot.
