At 9:03 a.m. Eastern Time, hijacked United Airlines Flight 175 from Boston crashed into the south side of the south tower of the World Trade Center.

The plane, a Boeing 767 jet, burst into flames as it struck floors 78 through 84. The impact destroyed support columns but did not cause immediate collapse.
