SYNOPSIS: Capt. Henry L. Mosburg was a pilot assigned to the 114th Assault
Helicopter Company. On September 26, 1966, he was assigned a combat assault
mission in the Delta region of South Vietnam over Vinh Binh Province. He
departed with a crew of four, including himself.
On the second pass on a target near the mouth of the Son Co Chien River,
Mosburg's aircraft was fired on by small arms. As the aircraft prepared for
a third pass, it was noticed that one of the helicopter's rockets was on
fire on the left side of the aircraft.
Observers watched the tail section of the aircraft fall away, causing the
helicopter to fall toward the water in a steep spin. The helicopter landed
on its right side in approximately nine feet of water. One person (unnamed)
was rescued, and one body was recovered. Mosburg was not found, nor was his
gunner, SP4 Marvin F. Phillips.
An exhaustive ocean search was made surrounding the crash area, but no trace
of Phillips or Mosburg was ever found. Because of the over-water area, it
was considered that the two were killed, and that it would be impossible to
recover their remains.
