I still do not totally agree on the sudden power up to go around, since he had allready hit the other guy with his prop which easily could have messed up the prop blades which would have given the sound of a power up. The crasgh was caused by collision with another plane and intanglement with the other plane. Its pretty clear that his left wing tip was caught under the other plane, and leveraged him to flip to the right.
I don't know about trying to go around, but the aft pilot had a last second reaction.
At least, he input elevator up.
He reacted because he saw or heard something.
I believe that the crash would have had a different result if there wouldn't be been avoiding reaction.
Just think about it: aft plane would have never lift, it would have just pushed the forward plane, doing more damage to it.
