The National Security Act of 1947, the legislation that created the US Air Force, was signed by President Harry S. Truman while on board the VC-54C.[1] He replaced the VC-54C in 1947 with a modified C-118 Liftmaster, calling it the Independence after his Missouri hometown. It was given a distinctive exterior, as its nose was painted like the head of a bald eagle. The plane, which included a stateroom in the aft fuselage and a main cabin that could seat 24 passengers or could be made up into 12 sleeper berths, is now housed at the National Museum of the United States Air Force in Dayton, Ohio.[13]
