From Wiki: To elude firemen that were descending toward him in a window-washing machine, Goodwin swung across the building with a rope. The fire department responded by attempting to knock him off the building with water from a fire hose. When this effort failed, the fire department on the inside of the building used fire axes to shatter window glass near Goodwin and then, through the openings in the glass, attempted to dislodge Goodwin from the building with grappling hooks attached to long poles. Chicago’s Mayor, Jane Byrne, intervened, allowing Goodwin to continue to the top.
