We've all seen people doing silly, stupid or just not well thought out things. We've all also seen people doing things unwittingly or without intention such as fly enroute in 5-6 ship formation through a busy parachute DZ circuit without so much as a radio call while parachutes are raining down around them, watched as a opposite direction traffic loomed large in our cockpit windows while on downwind at a busy CTAF(R) while the culprit was off with the fairies on 126.7 while they should have been on the right CTAF frequency..... etc etc....
We are all human, let he or she who is without sin...
