Extreme Buildering, Moscow, Russia

In the 1980s, Dan Goodwin, aka SpiderDan, aka Skyscraperman, in advocacy for high-rise firefighting and rescue, scaled many of the world's tallest buildings and structures including the Sears Tower, the John Hancock Center, the North Tower of the World Trade Center, the Parque Central Complex in Caracas, Venezuela, and the CN Tower in Toronto, Canada. In 2010, Goodwin, now a stage four cancer survivor, scaled San Francisco, California's sixty-storey Millennium Tower to call attention to the fire department's inability to conduct rescue operations in the upper floors of skyscrapers.
At least six builderers became known as "The Human Fly", all from the United States, as follows:
• George Willig, who climbed the South Tower of the World Trade Center in 1977. Like Alain Robert, he was also known as "Spider-Man", after the comic hero who was first published by Marvel in 1962.
• John Ciampa, who climbed between 1942 and 1952. He was a stuntman and entertainer, and was also known as the "Flying Phantom" and the "Brooklyn Tarzan".
