The Marine task element’s responsibilities were expanded slightly in the first week of June when MACV directed Colonel Merchant to provide search and rescue (SAR) support for U.S. aerial reconnaissance operations which had begun over Laos and North Vietnam. After 7 June at least two UH-34Ds (one section) were positioned together either at Quang Tri or at Khe Sanh, ready to conduct SAR missions for downed American and VNAF pilots. While based at Khe Sanh the helicopters were also used to support Advisory Team One on Tiger Tooth Mountain. At Quang Tri the SAR helicopters operated from a clearing adjacent to a local soccer field. Years later, Marine pilots who had stood the SAR duty there would recall the incongruous sight of small Vietnamese boys playfully pursuing their soccer games alongside parked combat aircraft and a TAFDS bladder. In addition to normal support operations, HMM-364’s pilots devoted much of the second week of June to a search for Privates First Class Fred T. Schrenkengost and Robert L. Greer, two MABS-16 Marines who had disappeared from the Da Nang compound on 7 June. Intelligence reports indicated that both men had been captured by Communist guerrillas about five miles south of the airfield while sight-seeing on rented motor bikes. The aerial search produced no signs of the missing enlisted men but reliable Vietnamese sources reported that the Viet Cong had displayed them in several villages. The task element commander finally called off the fruitless search on 15 June, a full week after it had begun. Ground efforts by the South Vietnamese to locate the men continued but were also futile. The two Marines were never found.[11-C] [11-C] The status of PFC Fred T. Schrenkengost was changed from missing in action to killed in action, body not recovered, on 23 July 1974. The status of PFC Robert L. Greer was likewise changed on 14 November 1975. While the aerial search south of Da Nang was in its final stages, HMM-364 suffered its last aircraft loss in Vietnam when a helicopter crashed while carrying supplies from Khe Sanh to Major Gray’s Advisory Team One on Tiger Tooth Mountain. The accident occurred on 13 June when a UH-34D was caught in severe down drafts while attempting to land in the small landing zone near the top of the jagged 5,000-foot-high peak. The crew and passengers luckily escaped injury and were rescued but the aircraft was damaged too extensively to be repaired. Marines stripped the UH-34D of radios and machine guns and then burned the hulk. _Changing the Watch_
