Although this fire took place 21 years ago, it remains one of the most significant non-terrorist associated highrise fires in the last century of U.S. fire history. On that fateful evening of February 23, 1991, an alarm of fire was received by the Philadelphia Fire Department reporting a fire on the "upper floors" at One Meridian Plaza. Fire-due fire companies made their best guess assessment of the situation and began fire suppression operations.
