References to the "Swiss Cheese" model for this accident are misplaced. This wasn't a case of the 'holes lining up' - the holes were aligned before this aircraft ever left the ground when they dispatched with insufficient fuel. This was a case of playing Russian Roulette with the lives of over 70 people, further magnified by the flight crews apparent reluctance to admit what they'd done and declare a fuel emergency as soon as they were directed to hold. If they did indeed do this previously and got away with it, it was simply dumb luck - the bullet wasn't in the chamber that time.+
Those responsible (that didn't perish in the crash) should go to prison for a very long time.
