The bodies Chief Warrant Officer Donald Wann of Shawnee, Oklahoma, and 1st Lt. Paul Magers of Billings, Montana, were identified through DNA testing by the Armed Forces DNA Identification Laboratory in Hawaii.
Wann and Magers were killed June 1, 1971, when the AH-1 Cobra helicopter they were flying as part of a rescue mission was shot down in Quang Tri Province, South Vietnam, the military said.
Wann's daughter, Shannon Wann Plaster, said she has been trying since the early 1990s to find her father, and had known since July 2008 that human remains found near the suspected crash site could include his.
"It was just emotional — joy, happiness and just relief," she said. "It felt like a million pounds off my chest and off my back."
Attempts to find a phone number for Magers' relatives in Montana were unsuccessful, but the Montana National Guard issued a statement on their behalf, saying they were "extremely grateful and honored by the outpouring of support and condolences."
