Narrative: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 take-off 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."

Follow-up / safety actions
NTSB issued 2 Safety Recommendations
| Issued: 24-DEC-1970 | To: FAA | A-71-003 |
| THE FAA DETERMINE AND IMPLEMENT TAKEOFF PROCEDURES THAT WILL PROVIDE APPROPRIATE JUDGMENT WITH REGARD TO THE AIRPLANE\'S RATE TO THE V1 SPEED, PARTICULARLY FOR CRITICAL LENGTH RUNWAYS, AND FOR RUNWAY SURFACE CONDITIONS THAT MAY IMPEDE ACCELERATION. NOTE: A SIMILAR RECOMMENDATION WAS FORWARDED TO THE FAA ON 10/3/63. (Closed - Unacceptable Action) |
| Issued: 09-MAR-1972 | To: FAA | A-72-060 |
| In cooperation with the aircraft manufacturers and the National Aeronautics and Space Administration, utilize the results of already extensive research and accident investigation data to develop and implement major improvements in the design of transport aircraft interiors. Of particular concern are improvements in the crashworthiness of galley equipment, stewardess seats and restraining devices, and the flammability cabin interior materials.
