Sears Tower to open glass-bottom Skydeck in June

Visitors won't have to crane their necks to see straight down from the Sears Tower Skydeck when the building adds four glass-bottomed balconies, nicknamed "The Ledge," to its 50-mile views come June. The Skydeck on the 103rd floor of the building that is changing its name to Willis Tower, opened in 1974, and has--weather permitting--always provided a view of four states. But to see what's directly beneath them, visitors always had to get as close to the building's windows as possible. The Ledge is scheduled to open next month, according to a spokeswoman for the Skydeck.
