Ekranoplan!

That is a truely AMAZING machine, Anton. On the rusty pictures it almost looks too fantastic to have ever been able to move. It is like a huge piece of art. I had visions of an insane artist who worked on some abandoned Russian dock, used all the scrap material that was lying around and somehow built this Kaspian Sea Monster as a symbol of the coldwar madness, the arrogance of man and it's fascination for machinery.

But no, this thing is for real and once flew over the surface of the oceans. Already being a dinosaur on the verge of extinction by the time it could be put to use.

Here is a video of the monster in full flight. There are a few other versions floating by as well, but the original one Anton posted is the best, it shows up around after 4:40 minutes or so.
