Runaway Luggage Cart Goes Wild On Airport Tarmac. VIDEO

If you've ever flown through O'Hare airport in Chicago (one of the busiest), you know things can get crazy. But onlookers got quite a show, and airport workers got quite a scare as a runaway luggage cart almost rammed an airliner.

The driverless luggage cart appeared to have an accelerator stuck and it ended up driving in circles at an alarming speed, getting closer and closer to a parked jet. At the last moment, a quick thinking airport employee got into another vehicle and slammed into the luggage cart to bring it to a start.
