I know nothing about this titanic Lun Soviet ground-effect war-tank-plane-thing. The description (in Russian) contains a large number of specialized ground-effect tank-plane enthusiast vocabulary words that stymie Google Translate. It appears that it could traverse broken apocalyptic roads, frozen tundra, and water with equal ease, skimming below radar, too. But I can't say anything else for sure.
So I will say this: if you fed a hyperactive 12 year old lad a diet of old Astounding Stories covers and put him in the most boring math class of all time for 28 straight hours with a collection of fine pens and a binder full of doodling paper, he just might produce one of these.
