Oh heck no!
The protective layer of the Skydeck at the top of the Sears Tower CRACKED under visitors' feet!
Granted, it was just the ledges top protective layer that covers the stronger glass below it BUT must have been terrifying to see happen live in the moment!
Willis/Sears Tower reps say nobody was ever in danger and will be fixing it immediately.
NO NO NO! You will never catch me on that ledge!
