On 15 September 2003, a U.S. Air Force Thunderbird F-16C crashed during a Mountain Home, Idaho, air show. Capt. Christopher Stricklin attempted a "Split S" maneuver based on an incorrect mean-sea-level altitude of the airfield. Climbing to only 1,670 ft (510 m) above ground level instead of 2,500 ft (760 m), Stricklin had insufficient altitude to complete the maneuver, but was able to guide the aircraft away from the spectators and ejected less than one second before impact. The pilot survived with only minor injuries; the aircraft was destroyed. US Air Force procedure for demonstration "Split-S" maneuvers was changed to require pilots and air controllers to both work in above mean-sea-level altitudes.
