SYNOPSIS: At the Air Force Academy, Clarence J. Hemmel was known as "Boo
Boo." He was well liked and expected to have a fine Air Force career
following his 1963 graduation.

After training on the F100 Super Sabre fighter/bomber, Hemmel was sent to
Vietnam. There, on October 21, 1967, his plane was kit by enemy fire,
crashed, and Hemmel was presumed to be dead. His last known location was due
east of the city of Tam Ky near the coastline of South Vietnam.

Hemmel probably did not survive that day in October, so it was
disappointment his family felt, not shock, when he did not miraculously
return with 591 released American prisoners in 1973. But military officials
were shocked that hundreds of Americans known or suspected to be prisoners
were not released.

Since the war ended, thousands of reports have been received by the U.S.
Government that relate to Americans still held captive in Southeast Asia.
The Government maintains that it cannot verify any single report, but the
official "assumption" is that at least some men are there. Experts maintain
there are hundreds, but the U.S. has not found the formula to bring them

Clarence Hemmel may not have survived, but some of the men he flew with did.
One can imagine that "Boo Boo" would gladly fly one more mission for them.
It's time we brought them home.

Captain Clarence Joseph Hemmel, who joined the U.S. Air Force from Missouri, was a member of the 612th Tactical Fighter Squadron. On October 21, 1967, he piloted a single-seat F-100D Super Sabre (tail number 56-2965) as the second of two aircraft on a combat support mission over South Vietnam. Shortly after leaving the target area, the flight leader on the mission lost radio contact with Capt Hemmel. A forward air controller in the area then reported seeing an explosion on the water about five miles east of Tam Ky, South Vietnam, in the vicinity of (GC) 49P  BT 430 280. Search and rescue vessels were dispatched, and one that was investigating the crash site inadvertently caught an unidentified set of possible remains in its propeller, rendering them unrecoverable. Further attempts to locate Capt Hemmel were unsuccessful, and he remains unaccounted for. Today, Captain Hemmel is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific.
