A-6A Intruder BuNo. 154164 of VMA(AW)‑533, MAG‑12, US Marine Corps, based at Chu Lai Air Base: Destroyed on combat operations May 2, 1968 when shot down by AAA during a Dawn strike on vehicles five miles northwest of Dong Hoi, Quang Binh Province, North Vietnam, at approximate Coordinates: 16'46.58" North 107'01.57" East.

Aircraft was lost while on a Tally Ho Mission in the northern part of Route Package One. Radar and radio contact was abruptly lost at approximately 05:40 hours. The fate of the crew - 1st Lt Thomas D Clem and 1st Lt Robert Douglas Avery - is not known, but they were presumed KIA on July 22 and September 4, 1974 respectively

On Tuesday, July 2, 2002, the Richmond Times-Dispatch reported that the wreckage of Avery's A-6A had been found during the search for another downed aircraft:

"In 1995, nearly three decades after Avery's plane disappeared, a joint U.S.-Vietnamese team was probing the coast of Vietnam for another airplane, part of a continuing effort to locate unaccounted- for veterans. On a narrow, sandy plain near a row of scrub pines, they found a brackish-water- filled crater they would later confirm as the crash site of an A-6A. The pilot of that plane was Lt. Thomas Dean Clem. His friend and crew mate was Robert Douglas Avery."

The article quotes Lt Commander Jerry O'Hara, a spokesman for the Joint Task Force, as saying that "We know we had the right aircraft. We found personal effects. We found crew materials. We found human remains [but they] have no DNA potential." As of 20 Feb 2004 the US Government has not announced the positive identification of either Avery's or Clem's remains.
