Analysis of Monday's crash of National Air Cargo Boeing 747 freighter in Bagram airbase in Afghan:
Boeing 747 steadily climbs to about 200ft (60m) above airfield level, just after take-off, with an extremely high nose-up angle, usually did in hostile areas, to reach a safe altitude quickly, within the airbase perimeter.
Within about 3s of appearing on film the aircraft's port (left) wing begins to drop, and 1s later the roll reverses, the right wing dropping. Simultaneously, the 747 begins a dramatic yaw to the right, the nose dropping fast. The roll stops at an angle of about 110deg to the horizontal, by which time the forward airspeed is well below flying speed and the aircraft is just falling sideways through the air.
As some airspeed is recovered in the fall, the pilots manage to roll the wings level, but the airplane stalls.
