The Shuttle Training Aircraft or STA lands on the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida.

Under cloudy skies painted by a setting sun, the Shuttle Training Aircraft, or STA, piloted by space shuttle Endeavour’s STS-126 commander, Chris Ferguson, lands on the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. Ferguson is flying the STA to practice landing a shuttle on the runway. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate a shuttle’s cockpit, motion and visual cues, and handling qualities. In flight, the aircraft duplicates the shuttle’s atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Ferguson previously served as pilot on the STS-115 mission, which flew in September 2006. The STS-126 mission to the International Space Station is targeted to launch Nov. 16.
