Allison’s horrifying wreck at Pocono ended his Hall of Fame career. At the very beginning of the race, Allison felt a tire problem and radioed his crew to prepare for a pit stop at the end of the first lap — but the tire Allison exploded, sending Allison’s Buick into a spin and into the second-turn wall. Cars began to move to avoid hitting him, but Chauncey T. Maggiacomo could not see because of the smoke and his car T-boned Allison’s car.
Both drivers were knocked unconscious. Maggiacomo awoke quickly and was treated at the infield medical center for a cut chin and hand and was released. It took medical and safety crews more than a half hour to extricate Allison from his destroyed car, and they needed to use the Hurst “Jaws of Life” tool to do so.
He was left with partial amnesia as a result of the accident that also left him with a steel rod in his left leg. During his subsequent six-week stay in the hospital, he also had to have surgery to reduce swelling on his brain.
