But Dog, isn't that also a part of training sometimes pushing it to the limits? Had the wheel chock been secured the accident would not have happened correct? One question is if the pilot was proficient to perform this maneuver and if it was a recognized tactical maneuver.
When you are at the controls, and in charge of other people's lives, you don't break the rules to 'show off'. Every military pilot knows this. There is the famous story of a kid in Navy Flight training that was considered to be the best flier anyone had ever seen. Everyone was sure this kid was going to be the best fighter pilot that the Navy ever produced. On his last training flight, the kid performed an unauthorized barrel roll.
His class standing was dropped from 1st to last in the section, and he never saw the inside of a fighter jet, and left the military at his first opportunity. You don't screw around with the hardware. You can die and take a lot of folks with you. No excuses.
