REMARKS:

SYNOPSIS: WO Mark J. Robertson, pilot, and Sgt. Joseph R. Pietrzak,
observer, were flying aboard an OH6A helicopter on a visual reconnaissance
mission in Thua Thien Province, South Vietnam on February 10, 1972. The
helicopter was hit by heavy 51 caliber machine gun fire in the power
compartment and fuel section. It burst into flames and fell vertically and
exploded on impact.

Other helicopters in the area immediately attempted to land and search the
area for survivors, but the crewmen reported that enemy fire and
deteriorating weather conditions prevented them from doing so. None of the
crews conducting visual searches saw survivors or bodies around the blazing
helicopter. Radio frequencies were monitored for a period after that, with
no result. Enemy activity in the area prevented further search in the loss
area near the Laos border.

It was concluded that Robertson and Pietrzak were dead, but their remains
were never recovered, and their names are among those counted missing,
prisoner, or unaccounted for from the Vietnam war.

Since 1975, nearly 10,000 refugee reports have been received by the U.S.
Government relating to Americans missing in Southeast Asia, convincing many
authorities that hundreds remain alive today. Although Pietrzak and
Robertson apparently are not among those said to be alive, one can imagine
that they would gladly fly one more mission to help bring their comrades to
freedom.
