Just two weeks after it opened to a nervous public, a walkway in China's central Henan province was evacuated after cracks appeared.
Reports describe visitors running and screaming in panic as they saw the damage on the U-shaped path at Yuntaishan (Yuntai Mountain) Scenic Park.
"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."
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 and over a drop of more than 100 meters.
'No threat to safety'
The park issued a statement next day, admitting discovery of "a 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."
This level of damage was disputed by the Weibo user who claimed to have seen it.
"It was definitely not a small amount of cracks," the user wrote. "The whole pane looked fractured."
Glass bridge mania
The park said the path will be shut temporarily until the broken pane is replaced.
Yuntaishan's management emphasized that such damage isn't unheard of among glass-floored attractions around the world, pointing to an incident in 2014 involving London's Tower Bridge
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.
Zhangjiajie Grand Canyon bridge
is due to open in Hunan province later this year, about 300 kilometers (186 miles) northwest of Shiniuzhai.
When completed, the Zhangjiajie structure will be the world's highest and longest glass bridge -- 430 meters long and 300 meters high.
