When discovered he was not on the aircraft, the hijackers flew to Syria and released all but 2 Israeli passengers. The hijackers proceeded to explode a bomb in the cockpit after the hostages had disembarked. Extensive repairs put the aircraft back into serve until 1980. (AP Photo/Matt York)

It is the world’s largest airplane repository and preservation facility, providing long- and short-term aircraft storage, parts reclamation and disposal for all types of planes.

As sunrise illuminates the facility’s 2,600 acres, the relics it holds evoke thoughts of missions past:

— An Army One helicopter that transported President Dwight D. Eisenhower in the 1950s.
— An old TWA jet that was once hijacked and bombed.
— An aircraft that spent 16 years preserved entirely under Antarctic snow before returning to flight and ending up in the sweltering desert heat.

Notably, the last aircraft to leave Saigon as it fell to North Vietnamese forces sits alongside disassembled Cold War bombers. The B-52s have their tails removed — one of the terms of a post-Cold War treaty with Russia to provide proof the bombers were indeed decommissioned.

The 309th Aerospace Maintenance and Regeneration Group was established in 1946 as the 4105th Army Air Force Unit to house planes after World War II.

It quickly expanded to aircraft from all military branches due to Tucson’s low humidity, minimal rainfall and high altitude, all of which ward off rust and corrosion. The hard soil makes it possible to move and secure aircraft without the need for pavement.

Today, the boneyard serves as both a testament to U.S. air prowess and a means to keep the country and its allies in flight through reclamation and restoration.

Thank you for a wonderful gallery. Maryland is my home state, so I follow the Baltimore Sun. The Martinsburg ANG plane photos really touched me… I have a personal connection to the 167th and 157th. And I live in Arizona now, so this was a triple treat. Amazing work!
