McDonald, O. This is the only video I have personally seen that was taken inside when US Steel still operated the McDonald Works, and a home movie at that! In addition to hot steel being rolled, there are shots of the no. 14 and no. 15 overhead cranes.
The video is courtesy of Chris Kalis, who's late father Michael "Mickey" Kalis, is pictured in the video. In addition to being a craneman at the McDonald Works, he was an Army veteran, published musician, home builder, and owned both Siciliano's Restaurant and the Calabria Lounge on the Westside of Youngstown. Sounds like he lived a full life.
