The Shuttle Landing Facility covers 500 acres (200 ha) and has a single runway, 15/33. It is one of the longest runways in the world, at 4,572 m (15,000 ft), and is 91.4 meters (300 ft) wide.[1] (Despite its length, astronaut Jack R. Lousma stated that he would have preferred the runway to be "half as wide and twice as long".[3]) Additionally, the SLF has 305 meters (1,000 ft) of paved overruns at each end.
