"The pilot was given directions to land either on runway one or two," Mr Malik said. "The plane was at 2,600ft before landing but suddenly it went to 3,000ft, which was unexplained."
He added that instead of approaching the airport from the "Kahuta side", a nearby town to the east, it attempted to land from "the Murree Road side", located to the north.
The plane's final moments are likely to remain a mystery until the black box flight recorder is recovered and studied. The flight had been descending as heavy monsoon rain and thick fog reduced visibility. For reasons that remain unclear, the plane turned northwards, flying for some 10 miles before crashing into the hills.
