This happened at Fort Knox back in 1986. One of our tanks was being worked on, the throttle was locked open, it was in gear and the crew member bypassed the starter relay switch and started the tank which promptly took off on a little cruise through the motor pool and the surrounding countryside by itself. The tank eventually came to rest on a small hill that it couldn't get up and we recovered it from there. Luckily the path of destruction was small and no one was injured. Ironically, this car belonged to the mechanic working on the tank and he did not get reimbursed by the Army because he was parked in an area marked with no parking signs, he did however get a ticket for illegal parking.
