Glass Sky Deck Shatters!

Willis Tower (formally known as Sears Tower) is a 108 story skyscraper in Chicago.  I had been wanting to do a strange spot post about the  tower's 'Skydeck' for a while,  but after stumbling upon an article online,  today is the day!  It takes about 60 seconds to make it to the top of the building where you will find the Skydeck (on the 103 floor).  The building sways on windy days and views can be seen all the way across Lake Michigan to Indiana, Michigan and Wisconsin.   If that's not exciting enough,  all glass boxes were installed on the side of the building to allow visitors to look through the floor 1353 feet down!   Today, May 29, 2014 the (almost) unthinkable happened, an acrophobic's nightmare!!! A trusting family of four walked into the glass box enclosure and it SHATTERED!  Visitors are informed the glass is unbreakable and can withstand 4.5 metric tons.. apparently NOT!   Fortunately, all four walked out of the glass enclosure safely.  Officials from the Willis Tower said they'll release a statement about the incident later on Thursday.  Wonder if the four young adults were jumping. Regardless, I'm fairly confident that they can't jump 4.5 metric tons of weight....
