Unlike smaller buildings, skyscrapers generally don't have operable windows. Why not?
Two window washers got stuck on broken scaffolding outside 1 World Trade Center today, and spent hours dangling precipitously at a 65-degree angle. Emergency workers had to cut out a window from the just-opened skyscraper to rescue the workers, who got stuck near the 68th floor around 12:45 p.m. when one of the cables that holds up the scaffolding they were working on came loose, according to CBS News.
