Kevil Klauer said he was waiting for a flight to Tennessee at the Chicago airport Monday when the scene unfolded outside of a nearby window. Advertisement Klauer tweeted a video showing the vehicle, which did not have a driver, driving in fast circles, spilling trays and food onto the ground. "At first it was humorous to see this drive itself and not fall over, but then as it picked up speed it presented danger to people," Klauer told CNN. The cart appeared to be about to strike a nearby plane when an employee in another vehicle rammed the cart, knocking it onto its side. Witnesses applauded. American Airlines said no one was injured during the incident. The airline said the cart's accelerator got stuck. There was one 10-minute delay to a flight as a result of the incident.
