| North Tower | 8:46 a.m. : IMPACT The first plane crashes into the tower's north face near the 96th floor. The impact ignites more than 20,000 gallons of jet fuel and scrapes away fireproofing insulation on the columns and floor trusses, exposing the steel to temperatures as high as 2,000 degrees Fahrenheit from the burning fuel.
