In honor and memory of the World Trade Center buildings in 2001. On September 11th, 2001 hijackers flew two Boeing 767 jets into the Twin Towers in a coordinated act of terrorism. At 8:46 a.m., a team of five hijackers intentionally crashed American Airlines Flight 11 into the northern facade of the North Tower. At 9:03 a.m., a second team of five hijackers intentionally crashed United Airlines Flight 175 into the southern facade of the South Tower. After burning for 56 minutes, the South Tower collapsed at 9:59 a.m. At 10:28 a.m., the North Tower collapsed, after burning for 102 minutes. The attacks on the World Trade Center killed 2,753 people. The resulting collapse caused structural failure in many of the surrounding buildings as well, and the entire complex was soon destroyed. In 2002, ground was broken on construction of a new 7 World Trade Center building located just to the north of the main World Trade Center site. (Info provided by Wikipedia.
