UPS jet narrowly avoids collision at Louisville airport as controller shouts 'What are you doing?'

A UPS Boeing 767 inbound to Louisville Muhammad Ali International Airport aborted its landing after nearly colliding with a smaller SKQ-25 taxiing on the runway; air-traffic control audio captured a controller shouting, 'What are you doing?' The crew executed a go-around and the FAA said required separation was maintained. This incident occurred at the Louisville hub, at the same airport where a fatal cargo-plane crash five months earlier killed 14 people.
