Bantam car in mid-air. This photo was taken in 1941 at New River, North Carolina during early testing of the Bantam jeep, the forerunner of the Willys MB and Ford GPW jeeps that became the World War II standard. This photo of the Bantam has all four wheels off the ground (six if you count the towed 37mm Antitank gun), the inspiration for the "Flying Jeep" poster and similar depictions.
U.S. Army Signal Corps.
1941
