Post edited and updated to present the full original video, which includes vignettes of the steel men at home, their children at school, and their symphony orchestra. The country is at war, the outcome is still in doubt, and yet the message is optimistic.
There are a number of action shots among the furnaces and mills. We'll see an open hearth crew poking the tap hole open with a long prod. I don't envy the front man, closest to the door. One wrong move ... The other ways to get the tap hole open are to use a stick of dynamite, or go underneath the furnace with an oxygen lance, both of which are risky as well.
Closing observation: "When the war is over, we're going to face problems." Yes, and the narrator probably didn't anticipate half of it.
