## Accidents and incidents

* On August 3, 1950 a United States Air Force Douglas C-47D was destroyed by fire after a take-off related accident. All five occupants survived the crash and subsequent fire.
* On October 2, 2006 a United States Air Force Learjet C-21A was on a training mission flying a simulated approach when speed unexpectedly dropped and called out "speed" two times. The pilot pulled back the number one engine throttle but the plane began to roll steeply to the right and struck the pavement before proceeding to skid through a grass infield and then across another runway before coming to a stop. Both occupants survived.
* On December 2, 2010, a single-engine home-built aircraft, a Southerland Freebird Litesport Ultra, took off from Decatur Airport and crashed 1.5 miles east of the airport. The pilot was the only person on board and was killed in the crash. The National Transportation Safety Board determined that the probable cause of the accident was "the pilot's reported inability to control his amateur-built airplane for undetermined reasons after the airplane inadvertently became airborne while conducting a high-speed taxi."
