All in all we're just another crack in the floor

I am already scared of heights.. but the thought of the floor cracking under me–while I’m on the 103rd floor!? No way..

That is exactly what happened to a family in Chicago.. They were on the tourist attraction, the Ledge, on the 103rd floor of Chicago’s Willis Tower. 

Even worse.. apparently after the family joked about how the stability is safe and glass floor is unbreakable, they began to hear cracking.. and saw it happening.

Never again.

I don’t think I’d be a person yearning to stand on a glass floor that high up to begin with, but hearing this I never will..
