In February 1951, Squadron Commander King, Charles Woolham and Voorhees Root placed a delayed action fused 1000 pound bomb right on target from low level. The delayed action fuse was to permit the aircraft to escape the bomb blast. The bomb exploded on impact destroying the plane and crew. An aircraft diving into the ground at high speed can make a big hole. When the hole is filled up and smoothed over you have your own piece of real estate for eternity.
Pilot error is sometimes an unfair category of cause.
