It is about a mega-ship. A wild valve, weighing 5 tons, broke. They show a guy who stands on the background of the valve and says - we spent an entire hour looking for the valve fault, and now it is clear that the thing is bad. And in the back is a valve the size of a car, in which, a frog, a crack of one and a half meters in length and a width of 3 centimeters.
Probably I don’t understand something about finding defects in the valves...
