Date of death: Saturday, May 17, 1975
Death details: Hostile, died missing, body not recovered, Cambodia; Marine Corps Pfc. Daniel A. Benedett of Seattle, Wash., was buried May 15, 2013 at Arlington National Cemetery, along with Air Force 2nd Lt. Richard Vandegeer of Cleveland, Ohio; Navy Hospital Corpsman 1st Class Bernard Gause Jr., of Birmingham, Ala.; Hospitalman Ronald J. Manning of Steubenville, Ohio; Marine Corps servicemen Lance Cpl. Gregory S. Copenhaver of Lewistown, Pa.; Lance Cpl. Andres Garcia of Carlsbad, N.M.; Pfc. Lynn Blessing of Lancaster, Pa.; Pfc. Walter Boyd of Portsmouth, Va.; Pfc. James J. Jacques of La Junta, Colo.; Pfc. James R. Maxwell of Memphis, Tenn.; Pfc. Richard W. Rivernburgh of Schenectady, N.Y.; Pfc. Antonio R. Sandoval of San Antonio, Texas; and Pfc. Kelton R. Turner of St. Louis, Mo. On May 12, 1975, Khmer Rouge gunboats captured the S.S. Mayaguez in the Gulf of Thailand, approximately 60 nautical miles off the coast of Cambodia. After the vessel was taken to Koh Tang Island, U.S. aircraft began surveillance flights around the island. When efforts to secure the release of the ship and its crew failed, U.S. military forces began a rescue mission. Three days after the Mayaguez seizure, the Air Force dispatched six helicopters to the island. One of the helicopters came under heavy enemy fire and crashed into the surf with 26 men on board. Thirteen of the men were rescued at sea, leaving Benedett and 12 other service members unaccounted-for from the crash. Between 1991 and 2008, investigators conducted more than 10 investigations and excavations, led by Joint POW/MIA Accounting Command (JPAC). On three occasions, Cambodian authorities turned over remains believed to be those of American servicemen. In 1995, U.S. and Cambodian specialists conducted an underwater recovery of the helicopter crash site where they located remains, personal effects and aircraft debris associated with the loss. Between 2000 and 2004, all of the missing service members from this helicopter, except Benedett, were accounted-for. On January 30, 2013, Benedett was accounted-for. Scientists from JPAC and the Armed Forces Identification Laboratory (AFDIL) used circumstantial evidence and DNA process of elimination to account for his remains.

Service era: Vietnam
Military history: Staff sergeant.
Date of death: Saturday, May 15, 1975
Death details: On May 15, 1975, a CH-53A Super Stallion (tail number 926) with a crew of four took part in a rescue of the U.S. merchant ship SS Mayaguez, located off the coast of Koh Tang Island, Cambodia. The Super Stallion was damaged by hostile ground fire during the mission, causing it to crash into the water off the island’s coast, in the vicinity of (GC) TS 940 400. A rescue team was able to locate and recover three members of the Super Stallion’s crew immediately after the crash; however, the flight engineer could not be found. Further searches of the crash site could not be conducted due to heavy enemy presence in the area. The remains of the Super Stallion’s flight engineer are still unaccounted for.
Staff Sergeant Elwood Eugene Rumbaugh, who joined the U.S. Air Force from Pennsylvania, was a member of the 21st Special Operations Squadron. He was the flight engineer aboard the Super Stallion when it went down, and was the crew member who was not located following the crash. His remains were not recovered, and he is still unaccounted for. Today, Staff Sergeant Rumbaugh is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific.
