Following a navigator/bombardier course in the fall of 1941 and a brief stint on antisubmarine patrol duty with the 6th Reconnaissance Squadron at Muroc AAB, Roosevelt received a top-secret assignment to carry out clandestine reconnaissance flights over the Sahara Desert, with emphasis on French West Africa, with which the United States was not at war. Having been successful with this (Project Rusty), he was given command of the new 3d Reconnaissance Group at Colorado Springs. From Gibraltar and then Oran, Algeria, he led this unit in Operation Torch, the invasion of Northwest Africa in early November 1942. Roosevelt (with a pilot) flew the first U.S. reconnaissance missions over the theater in a borrowed RAF de Havilland Mosquito. This led to a long campaign for the U.S. adoption of this British aircraft, as Roosevelt held the American counterparts (modified Boeing B-17Cs and early Lockheed P-38s) to be inadequate and unlikely to survive in contested airspace.
