From a commenter on Youtube
The pilot did not just "screw up". The reports are that the plane was carrying several MRAPs (Google it) in the cargo hold, and one or more of them came loose (or were not properly secured in the first place) and slid towards the back of the plane during take-off. Try to find a pilot who can counter a sudden weight shift like that upon takeoff. It's not possible. The sudden weight transfer instantly changed the angle of the plane and stalled the engines. There was nothing he could do to save it.
The stupidity of some people is amazing...stalled the "engines" what a douche.
