A Jet Airways flight, with over 50 passengers on board, made an emergency landing on Monday, less than an hour after take-off from the NSCB International airport in Kolkata.

Airport sources said the Bhubaneswar-bound Jet flight, which took off from the airport at 6.20 p.m., came back at around 7.10 p.m. after the pilot informed the ATC that the plane’s smoke alarm went off when it was mid-air.

Though crew members could not detect any smoke or fire within the aircraft despite a thorough check inside after the smoke alarm buzzer went off, they did not take any chance, the sources said.

With all emergency procedures in place, the passengers were evacuated after landing and the aircraft was now being checked by experts.

Arrangements were being made to accommodate the stranded passengers in another Bhubaneswar-bound plane, the sources said.
