History: Collapse Of The World Trade Center, September 11, 2001, Lower Manhattan, New York City, United States

Brooklyn toymaker George Willig scaled the exterior of the south tower in 1977. In 1983, on Memorial Day, high-rise firefighting and rescue advocate Dan Goodwin successfully climbed the outside of the WTC's North Tower. His stunt was meant to call attention to the inability to rescue people potentially trapped in the upper floors of skyscrapers.
The 1995 PCA world chess championship was played on the 107th floor of the South Tower.
In January 1998, Mafia member Ralph Guarino, who had gained maintenance access to the World Trade Center, arranged a three-man crew for a heist that netted over $2 million from a Brinks delivery to the eleventh floor of the World Trade Center.
