OKLAHOMA CITY (AP) -- Military investigators say a collision between a crop duster and an Air Force jet happened because the civilian pilot wasn't flying at the correct altitude.
According to an Air Force report on the crash, Carl Dierk Nash may have been trying to ascend in the crop-dusting plane to the proper height when the crash occurred January 18th.
The 43-year-old owner of a flying service in Wheatley, Arkansas, died when his plane and a T-37-B from Sheppard Air Force Base in Texas crashed near Hollister.
The Air Force has concluded that the pilots of both aircraft didn't see each other in time to avoid the collision, which happened at about 5,000 feet.
Nash was delivering the plane from a Texas factory to a customer in South Dakota.
Air Force Captain Christopher Otis and Second Lieutenant Roderick James were returning from an area near Frederick where jets train daily.
The National Transportation Safety Board hasn't completed its report on the accident.
