The First Interstate Tower fire was a high-rise fire that occurred on May 4, 1988, at the First Interstate Tower (now Aon Center) in Los Angeles, California, a 62-story, 860 foot (260 m) skyscraper, then the tallest building in the city. The fire destroyed five floors of the building, injured 40 people, and caused the death of a maintenance worker, when the elevator he was riding opened onto the burning 12th floor.
