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. 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."
