a wetsuit disguised as a Spider-Man suit and using a climbing device he designed for the building, Goodwin scaled the 100-story John Hancock Center in Chicago. To elude firemen who were descending toward him in a window-washing machine, Goodwin swung across the building with a rope. The fire department, on the inside of the building, used fire axes to shatter window glass near Goodwin and then through the openings attempted to dislodge him from the building with grappling hooks attached to long poles. Chicago's mayor, Jane Byrne, intervened, allowing Goodwin to continue to the top. Goodwin said he made the climb to call attention to the inability to successfully fight fires in high-rise buildings. North Tower of the World Trade Center On Memorial Day, May 30, 1983, using suction cups for the first four floors before switching to a camming device he connected to the building's window-washing track, Goodwin scaled the North Tower of the World Trade Center in New York City. Goodwin attached an American flag, the same one he taped to the Sears Tower in 1981, to the upper-most floor of the North Tower in tribute to Americans who died in war. Goodwin said he made the climb to call attention to the inability to rescue trapped occupants from the upper levels of skyscrapers. CN Tower On June 26, 1986, Goodwin scaled the world's tallest structure (not building) at the time: the CN Tower in Toronto, Ontario. Using his hands and feet, Goodwin climbed one side, rappelled down, then climbed the far side of the tower, followed by another rappel. Goodwin's climb was a sponsored publicity event celebrating the CN Tower's tenth anniversary. Millennium Tower On September 6, 2010, Goodwin scaled the Millennium Tower in San Francisco, California, United States. In tribute to the United States, Goodwin attached a United States flag to the top of the Millennium Tower, the same flag he attached to the top of Chicago's Sears Tower in 1981 and to the top of the North Tower of New York's World Trade Center in 1983. Goodwin said he made the climb to call attention to the inability to conduct rescue operations in the upper floors of skyscrapers. In addition, as a Stage Four cancer survivor, Goodwin wanted to inspire people throughout the world who have been diagnosed with cancer. Torre Telefónica Chile On March 1, 2014, Goodwin scaled the Torre Telefónica Chile in Santiago,
