I was thinking about this post in my accounting class tonight (I have my priorities straight, as you can tell), and I was thinking about spins. What makes an airplane spin? Stall + uncoordinated flight = Spin.

It could be that he pitched it up with insufficient speed, and stalled it. The counter clockwise rotation of the motor would cause the right wing to drop on the stall. Then, if he added rudder, that would have introduced the right conditions for a spin.

Considering that neither the airplane or the engine survived, it must have nosed in. This would be consistant with a spin as well. Obviously due to the brevity of the flight, the spin coulnd't have been very developed.

Just a thought.
