This happened yesterday at O’Hare, a catering cart decided that it had enough and ran away from its operator.
Jokes aside, a water jug fell from a catering truck and fell (coincidentally) onto the gas pedal. Therefor sending the truck spinning. The cart was then stopped by a ground crew member who rammed it with his own truck, sending the runaway cart flying onto its side.
I won’t add anymore context, as this is some hilarious stuff.
