1992: At the start, Mario and his son Michael led the field into the first turn. Michael came around in first, and Mario already a somewhat distant second. On the 5th lap, a caution came out. Mario ducked into the pits with a misfire. After several pit stops, the problem was fixed and he returned to the track, but dropped down the standings a lap down. Later in the race, Mario pitted for tires, and cross-threaded a wheel nut. He was again shuffled down in the running order. A few moments later, on a restart, he crashed in turn four. He was among several front-runners to crash due to cold tires on the unusually cold afternoon. Mario suffered broken toes, and was taken to Methodist Hospital in downtown Indianapolis for surgery. A short time later, Mario's son Jeff shattered both of his legs in a terrible crash, and was also taken to the hospital. Both required considerable rehabilitation, although Jeff's was significantly more severe. Back at the track, Mario's other son Michael was dominating the race, and looked poised to win. However, with 11 laps to go, his car quit, and he was out of the race. Ironically, the rival Unser family prevailed over the dismayed Andrettis yet again, with Al Unser Jr. winning and Al Unser Sr. finishing third. In his autobiography "Andretti", Mario described the day, which saw him laid up in a hospital bed, witnessing his youngest son's serious injury, and then woke up to hear the news that his other son Michael had lost, as the "worst day of my life."
