Worked in the factory. We produced steel tanks and our main customers were the military. As a result, we received a request to eliminate a leak in the tank at their base. They sent people who removed this flow by the method of cold welding. Further, according to the artist: we are coming, and there are more than 30 tanks and under three of them traces of decently leaked oil products. We examined all three, found a microcrack in only one of them. At first I didn’t understand how the microcrack was one under one of the three tanks, from this crack could only flow out 1-2 drops a month, and out of three as from under the crane. Then it came to me! Apparently, the head of the base noticed a drop, showed a fighting cleverness, poured several wheels of petroleum products under three tanks and informed the management that the tanks are running. Everyone arrested us, called us, we did our job and left, and on this basis he wrote down the previous stuff.
