747 Air Force One
*Stencil requires an ultra fine tip Sharpie* The idea of designating specific military aircraft to transport the president arose during World War II when military advisors in the War Department were concerned about the risk of using commercial airlines for presidential travel. In 1944, a C-54 Skymaster was converted for use as the first purpose-built presidential aircraft. Dubbed the Sacred Cow and operated by the Army Air Force, it carried President Franklin D. Roosevelt to the Yalta Conference in February 1945 and was used for another two years by President Harry S. Truman. The "Air Force One" call sign was created in 1954, after a Lockheed Constellation carrying President Dwight D. Eisenhower entered the same airspace as a commercial airline flight using the same flight number. Since the introduction of SAM 26000 in 1962, the primary presidential aircraft has carried the distinctive livery designed by Raymond Loewy.
