The flight left Karachi at 07:41 local time (02:41 UTC). Flight controllers at Benazir Bhutto International Airport lost contact with the aircraft at 09:41 local time (04:41 UTC). Weather conditions at the time were marginal, and the crew of a China Southern airliner had diverted to an alternate airport 30 minutes earlier. The impacts of this rainfall were not limited to the air crash. Pakistan experienced such heavy rains in late July 2010 that the entire nation experienced catastrophic flooding.
