A newly opened glass walkway, suspended 3,500 feet above a canyon in central China, cracked on October 5 to the terror of thrill-seeking tourists. The 1,300 foot long glass bottom walkway is built along Yuntai Mountain Scenic Park in Henan Province, China. The transparent U-shaped platform on Yuntai Mountain in Henan Province has proved a popular tourist attraction since it opened last month.

   Reports describe visitors running and screaming in panic as they saw the damage on the U-shaped path at Yuntaishan (Yuntai Mountain) Scenic Park.
Officials confirmed the cracks occurred after a tourist dropped a stainless steel mug on the walkway. Authorities have now closed the walkway for repairs, reported People's Daily Online.Opened on September 20, the Cliffside path spans 260 meters (853 feet), with a 68-meter glass-bottom (223-foot) section. It hangs at 1,080 meters (3,543 feet)

above sea level.  The park issued a statement next day, admitting discovery of small amount of cracks" during a regular inspection. "To ensure guests' safety, the glass walkway was closed immediately," the park's management said in a statement. "Safety experts were deployed to find the cause of the incident."
    It said the damage was caused by "external force" from a sharp object. There was no danger, it added. "The passage's surface is made of custom-made three-layer tempered glass panes. The cracks only affect one layer of the pane and will not pose threat to safety."Just witnessed a historic moment -- Yuntaishan's glass walkway is broken," wrote one user on Weibo (China's micro-blogging site) with the screen name "leedonghaeshuohyukjaenihaowodeai." 
  "As I was approaching the end of the passage, I heard a sudden loud 'bang.' My legs were shaken. I looked down and saw the pane underneath me had shattered. "Some people 

 screamed. I yelled, 'It really cracked. It really cracked!' Then I ran pushing the people in front of me. I was terrified."
Yuntaishan's passage is one of a recent series of glass-bottomed walkways to open in China. Shiniuzhai Park in Hunan province was opened last month, just in time for China's October 1 national holiday.
