Excerpted from A History of Marine Observation Squadron Six:
"On 29 September [1950], the squadron lost an OY aircraft and a HO3S-1 helicopter. The OY was shot down 5 miles north of Seoul, killing the aerial observer, Captain Edwin E Rives [Rivers]. First Lieutenant Arthur R. Bancroft was dispatched in a helicopter to rescue the pilot, Second Lieutenant Thomas D. Odenbaugh, but Bancroft's HO3S-1 was also shot down by enemy aircraft fire. Bancroft was killed in the crash, and Odenbaugh was declared Missing In Action on 29 September 1950."

"The squadron believed that Second Lieutenant Odenbaugh was taken captive but there was never any confirmation by the enemy of his capture, and he was officially listed as missing in action on 29 September 1950. His remains were never found, and he was declared killed in action on 2 December 1953"
