Chicago – Imagine standing on a glass deck hundreds of meters above a bustling city, only to hear the worst sound in the world – a crack.
Well, this is exactly what happened to tourists admiring the view of Chicago from the Skydeck on the 103d floor of the Willis Tower.
Mashable reports that just before visitor, Alejandro Garibay and his family stepped onto the glass deck to take in the sites, they were discussing the safety of the glass with staff members. Apparently one had jokingly said it’s ‘unbreakable.’
(Ummm… didn’t someone once say the Titanic was unsinkable… just saying)

Feeling reassured the Garibays stepped onto the deck 413 metres above the ground. Seconds later they heard a crack and were directed away from the glass box.
As soon as they took out their phones to photograph and take videos of the event, they were ushered away.
Shortly after the incident took place, building management tweeted from the @SkydeckChicago account, assuring visitors that it was only the protective glass coating that had cracked and that it was still 100% safe to visit.
The coating has, in the mean time, been replaced and the tower is still open to visitors
