September 15, 1961 – Three carpenters fall 43 stories to their death as a scaffold on which they are being lifted separates from the hoisting hook inside the core of the east tower of Marina City, under construction north of the river on State Street. Mike Einsele, a worker inside the core, says, ‘We were raising forms inside the core and I was about five feet above them. They were standing on the scaffolding, and I guess a cable slipped. I heard a loud noise and I turned around to look. The bodies bounced crazily, hitting one obstruction after another, until they hit the bottom. I heard the thuds when they hit and I got sick. I got out of there then.” [Chicago Tribune, September 16, 1961] Another worker, Will Bridges, who was working ten stories below the scaffold and who had just stepped out of the way to get a drink of water, said, “Everyone inside the core heard them fall.” Speculation about the cause suggests that the heavy forms on the scaffold that were being hoisted for the next phase of concrete work jammed against the wall of the core and twisted the hoisting hook enough so that the scaffold fell away.
