On one hand you have this lovechild between an Area 51 UFO x B52 bomber, on the other hand there's the (proven) rickety scrapheap of the Russian army. I would think that the Kremlin offices are worried.
Unbelievable piece of engineering. And when I see this shape, I want to believe that there's really something in the hangers of Area 51.
Also on YT. Action around 33:00'
