Only one C-5 plane in the world is on public display. I went to a museum on an active Air Force Base to see it.

There's only one place in the world where you can see a C-5 plane on permanent public display: the Air Mobility Command Museum on Dover Air Force Base in Delaware.Any C-5 would be impressive enough. As the largest aircraft in the US Air Force, C-5s are designed to haul tanks, missiles, helicopters, and other cargo anywhere they need to go.But the museum doesn't have just any C-5 on display. The C-5A Galaxy was the first and only aircraft to ever launch an intercontinental ballistic missile in flight.I visited the museum in May to tour the one-of-a-kind plane with Michael Hurlburt, the Air Mobility Command Museum's operations manager and an Air Force veteran. Take a look inside.

C-5s, the largest aircraft in the Air Force, are strategic lifters designed to move large amounts of cargo anywhere in the world.
