Hornets are mortally dangerous insects. Such one meter nest is a very rare thing to see. For obvious reasons it is not possible to disassemble it. The nest inner part is multilevel, and on its surface there
are many passages. In a case of emergency few hornets can easily kill a man, so it is necessary to be extremely cautious near nests. If any threat appears, all hornets attack at the same time.
The Red Banner submarine squadron was formed in 1938, but at that time it was called differently. By the way, the squadron changed its name many times. During its long and rich history, the squadron participated in WW II
and several science experiments. Currently there are 20 submarines there, some of them serve in the world ocean. Today we'll step aboard the nuclear-powered cruise missile submarine 949A Chelyabinsk.
