General Dwight Eisenhower addressed the staff of the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory during an April 11, 1946 visit to Cleveland. The former supreme commander of Allied Expeditionary Forces in Europe was on a tour of several US cities in the months following the end of World War II. The general arrived in Cleveland on his Douglas C-54 Skymaster, the 'Sunflower II'. Eisenhower employed this aircraft while leading forces during the war. Skymasters, the military version of the DC–4 transport aircraft, were used extensively by both the army and navy throughout the war years. NACA Secretary John Victory, Lewis Director Raymond Sharp, and local politicians formally greeted Eisenhower as he deplaned at the NACA hangar. After patiently posing for the press photographers, Eisenhower accompanied Victory and Sharp to the Administration Building for a press conference. The general made a point of downplaying the prospects for another imminent war. Afterwards Eisenhower was given a tour of the laboratory and addressed the NACA Lewis staff assembled outside the Administration Building on the importance of research and development. Eisenhower left the laboratory in a motorcade for a banquet being held in his honor downtown with the Cleveland Aviation Club.
