Sweet Mother of Marshal Zhukov! If there was ever a definition of Crazy Ivan, this thing is it. Oleg Antonov, answering a mandate from Uncle Joe's Flying Squad to come up with a method of airborne self-propelled armor delivery, invented this thing: the Antonov A-40 Tank Wings. Designed to be towed to an LZ by a bomber, it wasn't much of a tank and in 1942, the Air Force didn't have a plane powerful enough to tow it without overheating. However, it did fly successfully once. And really, once you've flown a tank, what is there left to do in life?
