Ken-----mate really? I don't work for Qantas or Virgin but I can tell you that if some bloke was banging heavily on my cockpit door only 3 feet behind my head then I sure as heck would seriously consider the appropriate course of action unless the cabin crew were able to resolve the situation.
You cannot be serious with your Monday morning quarterbacking of this incident WITHOUT knowing the facts.
As for the Indo's closing the Airport, that's their call mate and not Virgins. Sensible considering the situation they were trying to determine.
PULL YA HEAD IN.
