Although not an official presidential airplane, Franklin D. Roosevelt flew on a Boeing 314 Clipper “flying boat” (shown above) to meet with Winston Churchill to demand unconditional surrender from their Axis enemies. This trip across the Atlantic was the first time a sitting U.S. president flew on an airplane.
The first official presidential plane was a Douglas VC-54C called the "sacred cow" (shown above) It was placed in service in 1944. President Franklin D. Roosevelt was the first president to use this plane in 1945 just before he died. The plane featured an elevator that would lift FDR in his wheelchair aboard the plane.
Harry S. Truman named his plane The Independence (shown above) in recognition of his hometown ofIndependence, Missouri. It was the military version of the Douglas DC-6 and transported President Truman from 1947 to 1953.
