A visitor posted pictures of what she claimed was the cracked glass on Chinese social media. She said she could feel the shake under her feet the moment when the glass broke, reported People's Daily Online.

The U-shaped platform is attached to a cliff face on Yuntai Mountain, Henan Province, and opened to the public on September 20. Authorities have confirmed the incident and closed the tourist attraction for repair works.

A female tourist, who's known by her internet screen name 'lidonghaishuohezainihaowodehai', shared her experience of the terror on Weibo, the Chinese equivalent of Twitter, after she left the 853-foot-long platform.

She posted three pictures showing what she claimed was the cracked piece of glass alongside a message saying:

'[I've] just witnessed history. The glass-bottomed walkway on Yuntai Mountain just cracked. When I was about to reach the end [of the passage], I heard a sudden bang and felt a shake under my feet.

'I looked down and saw the glass floor beneath me shattered. [I have] no idea why it happened, at that moment everybody was screaming.

'I yelled out loud "It cracked, it really cracked!", then pushed the people in front of me to leave. [I was] terrified.'

A spokesman at the Yuntai Mountain Scenic Spot confirmed that a piece of glass had indeed broken on the walkway; the management had evacuated tourists and closed the passage for further notice.

The spokesman said the cracks occurred after a tourist dropped a stainless steel mug on the walkway. However, he said only one out of the three layers of glass broke, so the tourists were not in danger.

The see-through platform on Yuntai Mountain opened to the public on September 20.

According to its press release, 223 feet out of the 853-foot-long platform is paved with three layers of one-inch-thick glass panes, which is expected to bear the weight of at least 800 kilograms.
