FDR becomes first president to travel by airplane on U.S. official business
The secret and circuitous journey began on January 11, with the plane stopping several times over four days to refuel and for its passengers to rest. Roosevelt and his entourage left Florida, touched down in the Caribbean, continued down the southern coast of South America to Brazil and then flew across the Atlantic to Gambia.
They reached Casablanca on January 14. After a successful meeting with Churchill, as well as some sightseeing and visits to the troops, Roosevelt retraced the route back to the United States, celebrating his 61st birthday somewhere over Haiti.
