FAA and Air Traffic Control

A UPS cargo jet aborted its landing this week at Louisville Muhammad Ali International Airport after a smaller plane entered the runway without authorization. The Federal Aviation Administration said the smaller aircraft, calling itself Skylab 25, turned onto the runway without authorization and air traffic control ordered the UPS 767 to go around. FAA said required separation between UPS Flight 1303 and Skylab 25 was maintained, though audio shows a controller shouting, "What are you doing?" UPS told reporters the go-around was conducted safely with no injuries and no operational impact, and described the maneuver as a standard procedure.
