Unfallbericht:
Instrument weather conditions exited for the 10-minute ferry flight from Anchorage to Elmendorf AFB. Measured ceiling at 300 feet broken and at 1000 feet overcast; visibility was 5 miles in fog. During the GCA approach the DC-6 descended and struck the ground 1200 feet short of the runway. It appeared that the captain had used an rpm setting of 2200 instead of 2400 during the approach, power setting of 20" manifold pressure instead of 25" and a 40deg flap setting instead of 30 degrees. The first officer and flight engineer were aware of this, but didn't report it to the captain. Furthermore, the GCA controller advised the flight that it was below the limits of the glide path.

Probable Cause:

PROBABLE CAUSE: "The pilot used improper power and flap settings resulting in an excessive rate of descent which was continued until the aircraft struck the ground."
