From the Lawrence Daily Journal-World for Nov. 20, 1971:
Arson was suspected in four separate fires in four campus buildings at Oklahoma University. Lawrence banker Alan Hack, who with 300 others had been attending a banking conference in Norman, had been staying on the fourth floor of one of the buildings, a high-rise dormitory. At 4:30 a.m., he had been awakened by noise and the smell of smoke, after which he had stumbled into the hallway in an attempt to escape the blaze. Nearly overcome by smoke, he and another man had found a window and after three tries had managed to smash it with a chair. "Fortunately it was cold and in rushed a big gush of cold, fresh air," Hack said later. "We were really fading and I figured up to then it was all over. That may have been what saved our lives." The men had eventually escaped from the building, but six of the bankers were still in the hospital under observation for smoke inhalation.
