After visiting the Lyon Air Museum (finally) one thing that caught my eye (for reasons unknown) was the split flaps on both the B-17 and C-47 (likely others too that I missed, but that is just a reason to go back). A little googling led to Legends in Thier Own Time. This is a terrific collection of articles, cutaways (like the P-38 above) and other resources from the time that these aircraft were in service. If you cannot find something of interest on the contents page, maybe you don't like airplanes enough.
