I want to know why someone didn't just catch the croc so people would stop panicking. I've picked up a baby alligator before; the crocodile couldn't have been that much bigger to get on the plane as described.
I suspect that the passengers didn't realize that they were doing something dangerous when they all ran away from the crocodile at the same time.
An unusual incident. Are you obligated to be on the side of the plane with the crocodile if the other passengers are overbalancing the plane? To push other passengers over to the side with the crocodile?
