On January 11, 1943, Franklin D. Roosevelt becomes the first president to travel on official business by airplane. Crossing the Atlantic by air, Roosevelt flew in a Boeing 314 Flying Boat dubbed the Dixie Clipper to a World War II strategy meeting with Winston Churchill at Casablanca in North Africa. With German U-boats taking a heavy toll on American marine traffic in the Atlantic, Roosevelt’s advisors reluctantly agreed to send him via airplane. Roosevelt, at a frail 60 years old, gamely made the arduous 17,000-mile round trip.
