1st building crashes (8:46)
2nd building hits (10:28)
The attacks caused the deaths of 2,996 people (including all 19 hijackers) and injured more than 6,000 others. The death toll included 265 on the four planes (from which there were no survivors), 2,606 in the World Trade Center and in the surrounding area, and 125 at the Pentagon.
The new World Trade Center complex will eventually include five high-rise office buildings built along Greenwich Street, as well as the National September 11 Memorial & Museum, located just south of One World Trade Center where the original Twin Towers stood.
