An Air India Express Boeing 737 goes over a cliff and crashes upon landing at Mangalore, India, killing 158 of the 166 people on board. It is the worst crash involving a Boeing 737.

Air India Express Flight 812 was a scheduled domestic passenger flight from Dubai to Mangalore. On 22 May 2010, the Boeing 737-800 passenger jet operating the flight, crashed on landing at Mangalore. The captain had continued an unstabilised approach, despite three calls from the first officer to initiate a "go-around", resulting in the aircraft overshooting the runway, falling down a hillside, and bursting into flames. Of the 160 passengers and six crew members on board, 158 were killed (all crew members and 152 passengers); only eight survived. This was the first fatal accident involving Air India Express.
