Data Sources - Air Force Manual No. 200-25A, Department of the Air Force, Washington, October 16, 1961 page 1. Sanitized copy. National Archives KOREAN Conflict Casualty File (KCCF) 1950-1954.
03/92 -- Korea, and the men yet to be accounted for -- the "official list" -- is a list of U.S. servicemen known to have been
held as prisoners of war by the red Chinese and North Koreans from the Korean War
but not released or accounted for by the communists, as released on May 27,
1957 at a hearing of the House Subcommittee on the Far East and Pacific by the Department
of Defense.
The lists, the printed minutes of the May 27, 1957 hearing and the
"sense of congress" resolution were subsequently buried in the
archives. The original list had 450 names compiled from American POWS who were
repatriated by the Reds, as well as from photographs released by the Reds, Chinese
radio propaganda broadcasts, and letters written home by captured men. The "revised" list was narrowed down in august of 1961 to 389 men, and
all were arbitrarily declared dead by the military services, the USG still
lists them as "unaccounted for".
Names and ranks only were released at the time, and printed in "The
Spotlight" on August 27, 1979, along with the above information and background.
Further information has been compiled by the P.O.W. Network from the Hawaii POW/MIA
Korean Memorial records, National Archives documentation, and public United
States Air Force documentation, and changes made to the original published
information. (FEBRUARY 1992)
Clifford Mast is listed on the "HONOR ROLL OF FORGOTTEN AMERICANS" yet is noted as having died "while missing" by the National Archive.

On July 3, 1952, an RB-29 Superfortress (serial number 44-61727, nickname "So Tired") with thirteen crew members took off from Yokota Air Base, Japan, on a classified nighttime reconnaissance mission over North Korea. During the mission, "So Tired" was illuminated by enemy searchlights and attacked by a MiG-15 fighter, which inflicted severe damage. Eleven of the thirteen crew members bailed out before the aircraft crashed but were captured by the enemy and eventually returned to U.S. custody. The other two crew members were killed either by fire from the MiG or in the subsequent crash.
Staff Sergeant Clifford Henry Mast, who entered the U.S. Air Force from Washington, served in the 91st Strategic Reconnaissance Squadron. He was the nose gunner aboard "So Tired" at the time of its loss on July 3, 1952, and his body was reportedly found in the wreckage by enemy personnel but details of any burial are unknown. He remains unaccounted-for. Today, Staff Sergeant Mast is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific.
