The Air Force found Kopacek violated rules by flying too fast during three practice runs and the actual flyover, flying too close to ground level above a congested area, failing to report the altitude and speed deviation from the flight plan to superiors and making a false statement during the investigation
3 practice runs just to fly straight and level over a pretty obvious target? All of which bust limits (pretty wimpish limits, but nonetheless still briefed limits)...
Failing to report flying too low and fast? Oh come on - I cannot really imagine anyone saying "Oh, woe is me. I did fly lower and faster than I should have, oh master. I am unworthy; please flog me, for 'tis all I deserve!".
But making a false statement during the investigation. There is a code....
