The DC-8 operated on a flight for the Military Airlift Command (MAC) from Tacoma-McChord AFB to Cam Ranh Bay via Anchorage and Yokota.
The aircraft failed to become airborne while trying to takeoff from Anchorage runway 06R and overran. It struck a wooden barrier, an ILS structure, a 12-foot deep drainage ditch and caught fire.

PROBABLE CAUSE: "The failure of the aircraft to attain the necessary airspeed to effect lift-off during the attempted takeoff. The lack of acceleration, undetected by the crew until after the aircraft reached V1 speed, was the result of a high frictional drag which was caused by a failure of all main landing gear wheels to rotate. Although it was determined that a braking pressure sufficient to lock all of the wheels was imparted to the brake system, the source of this pressure could not be determined. Possible sources of the unwanted braking pressure were either a hydraulic/brake system malfunction or an inadvertently engaged parking brake."
