With no AC, food, 150 Biman passengers stranded inside flight at Kolkata Airport

The Biman boss today told our correspondent that as the pilot saw a red light flashing due to technical glitch, he aborted the take off.

Asked why the passengers were not taken back to the airport and made to suffer in this sweltering heat, the Biman MD said, the airport authority didn't give permission as they were assuming that the technical glitch might be fixed soon.

Zahid Hossain also said food couldn't be served to the passengers as repairing works were going on at that time.

He also said the air-conditioning system of the aircraft also didn't work which was fixed later. The Biman MD said after fixing all the problems, the aircraft is already fit to fly.
