This is what the bottom line should have read, according to all the reports of crashes I have heard a reason for:
1. Pilot error, the plane was flown even after a know problem had made itself apparent.
2. Pilot error, the pilot didn't secure the wing in a safe manner, (not enough rubberbands).
3. Pilot error, the pilot was flying (the airplane had to get in the air somhow).

Just havin' a little fun ya, thanks for the laugh.
