if you look at it as it climbs its turning up and to the right, and i would guess the load shifted to the tail which kept the nose up.
It was carrying several MRAP vehicles.
One or more broke loose on takeoff, dooming the flight.
Parts of the plane were left on the runway, iirc.
An MRAP weighs many tons.
