Even as late as World War II, it was thought that airplanes were too risky to let the President fly on one. But in 1943, President Franklin Delano Roosevelt flew across the Atlantic Ocean - to meet with Winston Churchill and demand the surrender of the Axis powers. It was the very first Presidential flight.
The First Lady, Eleanor Roosevelt, had a different concern. The President was going to miss his 61st birthday! So special arrangements were made — and they had a mid-air birthday celebration. See the photo in front of you? They’ve got birthday cake — and even champagne! The pilot is there on right — he drank coffee instead of the champagne.
