Source: Compiled by Homecoming II Project 15 October 1990 from one or more
of the following: raw data from U.S. Government agency sources,
correspondence with POW/MIA families, published sources, interviews.
Updated by the P.O.W. NETWORK 2021.

SYNOPSIS: The Lockheed C130 Hercules aircraft was a multi-purpose propeller
driven aircraft, used as transport, tanker, gunship, drone controller,
airborne battlefield command and control center, weather reconnaissance
craft, electronic reconnaissance platform; search, rescue and recovery
craft.

In the hands of the "trash haulers", as the crews of Tactical Air Command
transports styled themselves, the C130 proved the most valuable airlift
instrument in the Southeast Asia conflict, so valuable that Gen. William
Momyer, 7th Air Force commander, refused for a time to let them land at Khe
Sanh where the airstrip was under fire from NVA troops surrounding that
base.

Just following the Marine Corps operation Pegasus/Lam Son 207 in mid-April
1968, to relieve the siege of Khe Sanh, Operation Scotland II began in the
Khe Sanh area, more or less as a continuation of this support effort. The
C130 was critical in resupplying this area, and when the C130 couldn't land,
dropped its payload by means of parachute drop.

One base from which the C130 flew was Ubon, located in northeast Thailand.
C130 crews from this base crossed Laos to their mission areas in Vietnam.
One C130 crew from Ubon was comprised of LtCol. William H. Mason and Capt.
Thomas B. Mitchell, pilots; Capt. William T. McPhail, Maj. Jerry L.
Chambers [SEE NOTE BELOW], SA Gary Pate, SSgt. Calvin C. Glover, AM1 Melvin
D. Rash and AM1 John Q. Adam, crew members.

On May 22, 1968, this crew departed Ubon in a C130A carrying one passenger -
AM1 Thomas E. Knebel. Radio contact was lost while the aircraft was over
Savannakhet Province, Laos near the city of Muong Nong (suggesting that its
target area may have been near the DMZ). When the aircraft did not return to
friendly control, the crew was declared Missing In Action from the time of
estimated fuel exhaustion. There was no further word of the aircraft or its
crew.

The nine members of the crew are among nearly 600 Americans who disappeared
in Laos. Many are known to have been alive on the ground following their
shoot downs. Although the Pathet Lao publicly stated on several occasions
that they held "tens of tens" of American prisoners, not one American held
in Laos has ever been released. Laos did not participate in the Paris Peace
accords ending American involvment in the war in 1973, and no treaty has
ever been signed that would free the Americans held in Laos, and not one of
them has returned home.

William Mason was a 1946 graduate of West Point. Thomas Mitchell was a 1963
graduate of the Air Force Academy. Mason was promoted to the rank of Colonel
during the period he was maintained missing.

There is some information incorrect in this posting. LTC, then Major
Chambers was the passanger. LTC. Jerry L Chambers was a FAC assigned to the
23rd TASS at NAKOM PHANOM. During this flight he was present as an observer.

----------------------------------------------------------------------------------------

Just wanted to let you know, the group remains burial for the crew from this C-130 will
occur on 10 Jun 2010 at 0800 at Arlington National Cemetery. There will be a flyover
of the remains transfer at 9:00 a.m.

Here are the names of the crew:

Jerry L. Chambers; Calvin C. Glover; Thomas E.

Knebel; William H. Mason; William T. McPhail; Thomas B. Mitchell; Gary Pate;

Melvin D. Rash (all missing)

On March 13, 2009, the Defense POW/MIA Accounting Agency (DPAA) identified the remains of Colonel William Henderson Mason, missing from the Vietnam War.

Colonel Mason joined the U.S. Air Force from Arkansas and was a member of the 41st Tactical Airlift Squadron. On May 22, 1968, he was aircraft commander aboard a C-130 Hercules with a crew of nine on a nighttime flare mission over northern Salavan Province, Laos. The Hercules crashed during its flight, killing all nine of its crew. Immediate search efforts could not be conducted due to heavy anti-aircraft fire in the area. Between 1989 and 2008, joint Laotian, Vietnamese, and American search teams conducted field investigations and excavations in the Quang Tri Province of Vietnam, recovering aircraft wreckage and human remains. In 2009, modern forensic techniques were able to individually identify the remains of the crew of the Hercules, including those of Col Mason.

Colonel Mason is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific.

If you are a family member of this serviceman, you may contact your casualty office representative to learn more about your service member.
