6594th Test Group

The 6594th Test Group was a United States Air Force Unit stationed in Hawaii at Hickam Air Force Base from 1958 until it was deactivated in 1986.

The 6594th Test Group was established in 1958 to support U.S. Air Force Systems Command missile and space development operations in the Western Pacific area. It also provided support to the U.S. Coast Guard and Honolulu Joint Rescue Coordination Center on an as-available, non-interference basis.

Large portions of the Test Group's mission was classified until 1995 when information concerning Project CORONA was declassified. The 6594th was largely concerned with retrieving film canisters, about the size of a garbage can, in midiar that had been ejected from some of the United State's earliest spy satellites.

These canisters were among the first objects sent in to space that were designed to survive re-entry. Upon entering the ionosphere, they could resemble a shooting, or falling, star. Thus, the unit's motto "To Catch a Falling Star"

Because retrieval occurred over water in the Pacific, rescue swimmers were a standard part of the mission crew. Thus, when the 6594th was not busy with their primary mission, they were often available to support the US Coast Guard and other agencies in Search and Rescue (SAR) missions. The 6594th Test Group had one of the best records for open water rescues in the U.S. Air Force.

Personnel

At the time of deactivation, the 6594th was staffed by 95 officers and 409 enlisted personnel and was supported by 16 US Civil Service personnel.

Tragic Loss

On January 15, 1985 an HH-53 helicopter, call sign Arris 01, from the 6594th Test Group crashed while attempting a shipboard rescue mission 540 miles north of Honolulu. All seven crew members were killed: Pilots Capt. David D. Mason, Capt. Steve Pindzola, 2Lt. Russell Ohl. Flight Engineers SSgt Kyle D. Marshall, SSgt Daniel R. Reihman. Pararescuemen SSgt John R. Gilbert, Sgt Robert A. Jermyn. All seven made the ultimate sacrifice in keeping with the motto of air rescue, "That others may live." The helicopter crashed when the tail broke off while the helicopter hovered above the commercial ship, "Asian Beauty." Captain Mason had been married only a few days and returned early from his honeymoon to volunteer for the flight. A memorial plaque in honor of the seven crew members is located in the yard of the chapel at Hickam Field. For more information, see the publication of the Hickam Field annual reports.
