Investigators from US National Transportation Safety Board and the Afghan Civil Aviation Authority spent 12 days in Afghanistan studying the flight recorder from the Dubai-bound Boeing 747-400 that went down soon after takeoff April 29 at Bagram Air Field, north of Kabul.
The Taliban quickly claimed responsibility, saying it had shot down the plane, but NATO has consistently rejected that, saying there was no insurgent activity in the area.
"What is clear for us after this investigation is that the claim of responsibility for the Taliban is false," Qalatwal said today. "There was no sound of any rocket attack or any insurgent involvement in that crash. It was only an accident."
He noted that the plane was inspected only two hours before its takeoff and was found to have no technical problems. The American investigators took the flight recorder with them when they returned home, and Qalatwal said it could take up to a year to determine the exact cause.
Six of the dead Americans were from Michigan and the seventh was from Kentucky, said Shirley Kaufman, a National Air Cargo vice president.
