MOORE COUNTY, N.C. — A plane has crashed in southern Moore County. It went down just west of Aberdeen around 8 p.m. Friday.

Fort Bragg officials said it was a civilian plane that was contracted to the military. The plane, an L-410 used primarily for the transportation of cargo and passengers, had four people on board.

Two of the crash victims were airlifted to Womack Army Hospital at Fort Bragg. Two other people were taken to the hospital by ambulance. Their conditions were not immediately known.

Sgt. 1st Class Bobby Pruitt of the 18th Airborne Corps at Fort Bragg said the aircraft was owned by a civilian contractor working with special operations forces at Camp MacKall. He was not sure where the plane was headed or what its mission was.

Investigators are still trying to figure out what caused the crash.

The crash took place near Camp MacKall, a military site southwest of Fort Bragg. The Air Force and Army routinely conduct training missions in the area, especially at night.

Back in 1999, an Air Force helicopter crashed at Camp MacKall. The MH-53J went down in an open field, killing one airman. Five other crew members survived.

An investigative panel determined that the chopper crashed after the pilots became disoriented by a dust cloud.
