I thought that I had seen something like this before, and it turns out it was at the Museum of Army Flying, Middle Wallop. Although they only have a replica, if you can believe wikipedia, the Hafner Rotabuggy actually flew.
Wiretapping was around long before 1940. The French Resistance and the Jedburgh teams caused enough havoc to the telecommunications system to force the Germans to go back to using radio. The good folks at Bletchley Park had a field day once the Germans were forced to use radio again.
Appendix 6 of Niklas Zetterling's book "Normandy 1944" gives a daily cumulative total for US and British tank strength. It also gives tanks types for many of the units, but this information is not complete. The TO&E for the unit type is given but not necessarily the exact model of the tank.
The Mythical Man Month By Frederick P Brooks was always one of my favorites. It deals with the development of the operating system for the IBM 360 and is at least 40 years old. I believe you can download copies of it now, but I don't know if that is legal.

Eagle Against the Sun is good, but you need to back it up with an atlas as it has no maps. I use the West Point Atlas For the Second World War Asia and the Pacific. Both books are usually pretty inexpensive in used book stores.
