The Lockheed Constellation, C-69 in military form, probably has more fans and devotees than any other WWII transport, with the possible exception of the C-47/DC-3, and certainly the most among the 4-engined transports of the war. The Constellation was the subject of a Design Analysis [ HTML ] in the April, 1945 issue of Industrial Aviation magazine. That article provided the artwork that I converted into wallpaper images.
Air Tech also published a short design analysis [ HTML ] in their December, 1945, issue.
