The decision was made to leave Hartman before more men were killed trying to rescue him. It was not an easy decision, and one squadron mate said, "To this day, I can remember his voice pleading, 'Please don't leave me.' We had to, and it was a heartbreaker." Hartman was captured and news returned home that he was in a POW camp. However, he was not released in 1973. The Vietnamese finally
returned his remains on March 5, 1974. Hartman had died in captivity from unknown causes.

In July 1967, LCDR Donald V. Davis was one of the Saints of VA 163 onboard the ORISKANY. Davis was an aggressive pilot. On the night of July 25, 1967, Davis was assigned a mission over North Vietnam. The procedure for these night attacks was to drop flares over a suspected target and then fly beneath them to attack the target in the light of the flares. Davis and another pilot were conducting
the mission about 10 miles south of Ha Tinh when Davis radioed that he had spotted a couple of trucks. He dropped the flares and went in. On his strafing run, he drove his Skyhawk straight into the ground and was killed immediately.  Davis is listed among the missing because his remains were never recovered.

LTJG Ralph C. Bisz was also assigned to Attack Squadron 163. On August 4, 1967, Bisz launched on a strike mission against a petroleum storage area near Haiphong. Approximately a minute and a half from the target area, four surface-to-air missiles (SAM) were observed lifting from the area northeast of Haiphong. The flight maneuvered to avoid the SAMs, however, Bisz' aircraft was observed as it was hit by a SAM by a wingman. Bisz' aircraft exploded, burst into flames, and spun downward in a large ball of fire. Remnants of the aircraft were observed falling down in the large ball of fire until reaching an altitude estimated to be 5,000 feet and then appeared to almost completely burn out prior to reaching the ground. No parachute or ejection was observed. No emergency beeper or voice communications were received.

Bisz' aircraft went down in a heavily populated area in Hai Duong Province, Vietnam. Information from an indigenous source which closely parallels his incident indicated that his remains were recovered from the wreckage and taken to Hanoi for burial. The U.S. Government listed Ralph Bisz as a Prisoner of War with certain knowledge that the Vietnamese know his fate. Bisz was placed in a
casualty status of Captured on August 4, 1967.

The Navy now says that the possibility of Bisz ejecting was slim. If he had ejected, his capture would have taken place in a matter of seconds due to the heavy population concentration in the area and that due to the lack of additional information it is believed that Bisz did not eject from his aircraft and that he was killed on impact of the SAM.

Classified information on Bisz' case was presented to the Vietnamese by General Vessey in the fall of 1987 in hopes that the Vietnamese would be able to resolve the mystery of Bisz' fate. His case is one of what are called "discrepancy" cases, which should be readily resolved. The Vietnamese have not been forthcoming with information on Ralph Bisz.
