Abstract: On June 1, 2002, the tarmac crew supervisor was driving a two-baggage cart train when he signaled Employee #1, to disconnect one of the carts as the supervisor was maneuvering near the airplane to be loaded with the passenger bags. Employee #1 did not wait for the tow tractor to stop assuming the tow tractor was about to stop. When Employee #1 placed himself between the carts with the intention of disconnecting them, his left foot was caught by a wheel making him fall, and then the wheel ran over his leg up to his knee. Surgery was needed to repair the torn ligaments and tendons of his knee and ankle.
