So, what is it that caught my attention about My Tank Is Fight! Deranged Inventions of WWII? Well, doesn't the title say it all?
Perhaps even more than that, is the author's description of his work as "Pulp History." All of the things in this book wouldn't be out of place in the wildest pulp stories, and yet all were at least on the drawing boards, and a few actually saw prototype.
Things like the Panzer VIII Maus, the largest tank ever constructed (and it's possible larger cousin, the over 1000 ton Landkreuzer P.1000 Ratte). Flying tanks. The HMS Habbakuk, an aircraft carrier made from ice. A Nazi space station. A helicopter backpack. It's all in there, and more.
All of it with a fair degree of snarky commentary, which fits well with some of these harebrained schemes.
