Probable Cause
The inadequate visual lookout by the pilots of both aircraft, which resulted in their failure to see-and-avoid each other's aircraft and a subsequent midair collision. A factor associated with the accident was the airplane pilot's failure to determine that the aerobatic box was in use by the glider prior to his entry into the aerobatic box.
