Sue Is NOT Afraid Of Heights

Paul Is The Chicken

Oh Not... Here We Gp

If you're scared of heights, it may be time to look away now.  Not content with having the tallest building in America , the owners of  Sears Tower in Chicago have installed four glass box viewing platforms which  stick out of the building 103 floors up. The balconies are suspended 1,353 feet in the air and just out four  feet from the building's Skydeck.

Floating on air: Visitors get their first view from The Ledge, four  Glass balconies
suspended from the 103rd floor of Chicago 's Sears Tower .

Designers say the platforms - collectively dubbed The Ledge - have  Been purposely designed to make visitors feel as they are floating above the  City.       The reward is unobstructed views of Chicago from the building's west  Side and a heart-stopping vista of the street and Chicago River below - for  Those brave enough to look straight down.       'It's like walking on ice,' visitor Margaret Kemp, from Bishop,  California said. 'The first step you take you think "Am I going down?"'

Long way up: Even the floor of the platforms are glass - few were  Brave enough to look straight down.

 Fearless: People out on the floor of the 10ft square  box which is 1,353ft up.
Spectacular: She also enjoyed amazing views out across the city

Thrillseekers: The boxes jut out four feet from the building and were  Specifically designed to make visitors feel as if they are floating   'The Sears Tower has always been about superlatives - tallest,  Largest, most iconic,' he said. 'The Ledge is the world's most awesome view, the world's most  Precipitous view, the view with the most wow in the world.' The balconies are 10ft high and 10ft wide, can hold five tons, and  Have glass which is 1.5 inch thick.

  Inspiration came from the hundreds of forehead prints visitors left  Behind on Skydeck windows every week. Now, staff will have a new glass  Surface to clean: floors. Architect Ross Wimer said: 'We did studies that showed a  Four-foot-deep (1.2 metres) enclosure makes you feel like you're floating  Since there's only room for one row of people, not two.' Skydeck attracts 25,000 visitors on clear days. They each pay $15  To take an elevator ride up to the 103rd floor of the 110-story office  Building that opened in 1973.
