A reptile expert searched for the 6-inch (15-centimeter) -long snakes but did not find them. It was not known if the snakes were still on the plane or if they had somehow escaped outside after the plane landed.
Either this is their attempt to stow away and transfer to another continent, or they're simply going to end up choking someone in first class when they get hungry. Not all too certain how the food supply outside of 'human' looks like on airplanes ... last I checked, mice, rats, or other small rodents are not all too common ... but humans ... plenty of that business.
Anyone traveling to/from Australia, good luck, and have fun!
