A Lockheed C-5A Galaxythat at one time flew out of Dover Air Force Base came home to the adjacent Air Mobility Command Museum.
The aircraft will not be on display at the museum until November, according to a posting on its website. A ceremony is expected at that time to mark its arrival.
The aircraft rounds out the collection of transports at the museum. The C-5 flew in from Memphis where it was stationed with the Tennessee Air Guard.
It is the first of the giant aircraft to go to a museum. Some C5s are now being retired. Dover Air Force Base now has a combination of C-5 and C-17 transports.
The aircraft was part of a test to determine the feasibility of air launching an ICBM (intercontinental ballistic missile) from an aircraft. Over the years, the transport was based at Travis Air Force Base in California, and Altus and Lackland Air Force bases in Oklahoma and Texas respectively. The museum is looking for photographs and other information on the aircraft.
The C5-A was first introduced in 1970 during the Vietnam war. After cost-overruns and problems with its wing structure, it went on to become a workhorse for the Air Force. Some C5s, have undergone major overhauls to bring the jets up to date.
