Alitalia Flight 771 was a scheduled flight from Bangkok International Airport, Bangkok to Chatrapati Shivaji International Airport, Mumbai, with 94 on board. On July 7, 1962 it crashed into a hill about 84 km north-east of Mumbai while on approach. The accident was attributed to a navigation error which led the pilot to believe that he was nearer his destination than he actually was and, therefore, caused him to make a premature descent in instrument conditions for a straight-in approach to land at night.
