A video of Air India crew members walking along a jet bridge has been falsely presented online as showing the crew of Air India's flight AI171 boarding the aircraft that later crashed, killing all but one passenger.

The black box of the Air India jet that crashed and killed 271 people is still in India and is being examined by the aircraft accident investigation body, news agency ANI reported on Tuesday, citing civil aviation minister Ram Mohan Naidu.

A video of flight attendants waving to camera as they board an aeroplane was filmed prior to a flight from Saudi Arabia, contrary to posts claiming it shows the crew of an Air India jet that crashed moments after takeoff from the western Indian city of Ahmedabad.
