Pilots have been playing up and carving holes in the ground since day dot, I doubt it will ever be free of yahoos,,,,the only way to change the culture is from the inside,,we need to grow the balls to confront other pilots when behavior is crook and make it our business when we see stuff on the field that's wrong, RAAus has made it mandatory for yearly rego labels to be displayed on the left side of the windscreen , we all have a vested interest in taking notice of whether the aircraft around us are compliant .
We all have our bad pilot stories ,but how many can honestly say they've had the guts to say something , anonymous forums don't count though, no matter how often the rules are cut and pasted !
