“...I couldn’t imagine a boom knocking down walls....”
That one factory bldg (in one pic I saw) really suffered some upper-level damage. The pic stunned me; looked like it took a direct hit. Guess those spanning beams bent and collapsed like spaghetti.
A comment on the video said the factory was in bad shape already. Stalin moved much of the Soviet Union’s manufacturing to that area of the Urals during WW2.
