Circumstances:
Prior to takeoff, the local controller offered pilot choice of runways 01 or 28. The crew decided to takeoff from runway 01. During the takeoff roll, the airplane was caught by strong winds and control was lost. The airplane veered off runway, lost its undercarriage and came to rest in flames. Both pilots were injured and the aircraft was destroyed by fire.
Probable cause:
The crew selected the wrong runway relative to existing wind. The following factors were considered as contributing:
- Unfavorable wind component,
- Inadequate preflight preparation,
- Improperly loaded aircraft (W&B and CofG),
- Overload failure,
- Wind gusting up to 23 knots,
- Aircraft loaded aft of CofG.

Probable cause:
A second flight was completed in similar conditions few hours later and the investigators were unable to determine the exact cause of the accident.

Circumstances:
The aircraft overran the departure end of runway 29R at Stockton Metropolitan Airport, California, during the performance of a crew training flight. The aircraft struck a roadway thereby collapsing the left main and nose landing gears. The aircraft came to rest 792 feet beyond the end of the runway. The aircraft was destroyed by fire. The five crewmembers aboard were uninjured. The flight was scheduled for use for recurrent training and annual proficiency checks of first officers in DC-8 equipment. The flight originated at the Oakland International Airport (OAK) and was to terminate at OAK. Training maneuvers were to be conducted in the Stockton area, with landing and takeoff practice to be performed at the Stockton Metropolitan Airport. During a touch-and-go landing on Runway 29R at the Stockton Metropolitan Airport, the captain rejected the takeoff because of the sounding of a takeoff warning hob and the activation of a ground spoiler extend light. The crew was not able to stop the aircraft on the remaining runway.
Probable cause:
A false ground spoiler position indication during the takeoff portion of a touch and go landing that induced the captain to discontinue the takeoff at a point too far down the runway to permit him to stop the aircraft on the runway.
