At the height of the 103rd floor: the glass floor of the attraction burst under the feet of tourists (7 photos + 1 video)

There are several phobias, the presence of which is common to a large number of people. One of them is the fear of standing on the transparent glass of some tall structure, such as a house or a bridge. Of course, looking down can feel euphoric, but it can also be really scary.

But what if, while standing on such a transparent structure with a stunning view, you suddenly hear the unpleasant sound of cracking glass. At the same time, looking back, you suddenly notice that the surface on which you are standing has actually begun to become covered with cracks. What will you feel then? Probably, in this case, your heart will definitely be in your heels.

However, we would like to note that this is not just our wild imagination, since something similar actually happened in real life.

Last Monday evening, visitors to Chicago's Willis Tower were terribly surprised and even frightened.

On the 103rd floor of the skyscraper, a popular attraction among tourists is a transparent glass cabin from where they can enjoy panoramic views of the entire city, as well as nearby Lake Michigan.

True, this time the glass, which at first glance seemed quite durable, suddenly began to crack while tourists were on it.

A representative of the Skydeck Chicago observation deck noted that they had everything under control and none of the visitors would have been harmed.

At the same time, they noted that this is exactly how the protective layer should work.

This layer is said to crack because it is designed to protect the surface of the glass.

It is worth adding that the observation deck with transparent walls in Chicago's Willis Tower is visited by 1.7 million tourists annually. The Ledge Skydeck is definitely a popular tourist attraction, or so it says on their website.

“In 2009, Skydeck Chicago opened its newest attraction, The Ledge, 4 glass boxes that extend 4.3 feet (1.3 m) beyond the tower and sit 1,353 feet (412 m) above Wacker Drive. This is truly something unforgettable, since the cabin is made of glass on all sides.”
