A C-54E Skymaster named “Spirit of Freedom” sits on

A C-54E Skymaster named “Spirit of Freedom” sits on the tarmac at the Great Falls International Airport, Sept. 9, 2016. The Spirit of Freedom is a flying museum being flown all over the country by members of the Berlin Airlift Historical Foundation to help raise awareness of the Berlin Airlift. The airlift was a mission that saved nearly 2.4 million Germans from the Soviet-controlled East Berlin in the late 1940s and this is one of the only flight-worthy C-54s remaining in the world.
