Theodore Roosevelt
context: Franklin D. Roosevelt was the first president to fly in an aircraft while in office. The first aircraft obtained specifically for presidential travel was a Douglas Dolphin amphibian delivered in 1933 which was designated RD-2 by the US Navy and based at the naval base at Anacostia D.C. The Dolphin was modified with luxury upholstery for four passengers and a small separate sleeping compartment. The aircraft remained in service as a presidential transport from 1933 until 1939. There are no reports, however, on whether the president actually flew in the aircraft. During World War II, Roosevelt traveled on the "Dixie Clipper", a Pan Am-crewed Boeing 314 flying boat to the 1943 Casablanca Conference in Morocco, a flight that covered 5,500 miles (8,890 km) in three legs. The threat from the German submarines throughout the Battle of the Atlantic made air travel the preferred method of VIP transatlantic transportation.
