Historic C-5 Plane to Make Final Landing in Del. A historic military plane will make its final landing at Dover Air Force Base in Delaware. The Tennessee Air National Guard's 164th Airlift Wing is set to deliver the C-5A on Wednesday. The Air Mobility Command Museum says the aircraft will be part of the organization's collection. The museum says it's the only plane to successfully launch an intercontinental ballistic missile in flight. While the test over the Pacific Ocean was a success, the tactic was not pursued. During the next few months, the functioning military plane will be transformed into a museum piece. It will be officially retired in October and after a public ceremony in November, the plane will become the only C-5 in the world accessible to the public.
