The reactor pinned a man to the ceiling. 💀 . . . On January 3, 1961, at the SL-1 reactor near Idaho Falls, a control rod was pulled 20 inches too far. The core flashed to steam in 4 milliseconds and launched the 26,000-pound vessel 9 feet into the air. Navy Seabee Richard Legg, the shift supervisor, was found impaled overhead. He had to be buried in a lead-lined coffin.
