My husband had a model submarine for seven years. During this time, I learned all its composition and mastered the work on a token-freezer machine. I tortured specifically. But the matter is not that.
Finally let it go to the water.
They put the boat and took the binoculars. Let the man check all the mechanisms. Everything was fine, but the torpedoes were not checked.
In general, it turned out that the model of the yacht, which sailed nearby, went to the bottom.
The guy with the yacht - again sorry, he's accidental!
