A stowaway crocodile on a flight escaped from its carrier bag and sparked an onboard stampede that caused the flight to crash, killing 19 passengers and crew.
Note that these deaths were caused by human over-reaction to a fellow-creature who probably would have been satisfied with just one victim. I mean, how hungry could that croc be?
In the unlikely event of a crocodile
crawling along the airplane aisle,
there's no need
Just sit in your seat
and lift up your feet.
