The mind boggles. How much longer will their regulators accept this behaviour.
This can never be regulated out of existence, for the simple fact, man has an adrenalin system and an ego. It's the same reason people ride motorbikes fast, it's a buzz, simple. The only way it will ever stop is by banning aircraft altogether. Just google low flying, it's not uncommon, in everything from sapphires to 777's.
