Dare you lean off this 88th-floor walkway?
THE world's highest handrail-free walkway, on the 88th floor of Shanghai's Jinmao Tower, is an adrenalin-pumping attraction.
But few foreigners seem keen to take on the aerial challenge, citing safety concerns.
As of Friday, about 64 per cent of respondents to a questionnaire on the website of Britain's Daily Telegraph had indicated "no" to whether they would lean off the walkway, the Chinese media noted.
The walkway lies 340.6m above the ground. The upper observation deck of Eiffel Tower in Paris is 276m high.
Some Chinese netizens also disapprove of the attraction, which opened last week.
One user asked cynically: "Some Chinese need not risk their lives on their job, so they want to risk them in the name of 'living it up'?"
Called Skywalk In The Clouds, the open-air glass walkway on the 420.5m-tall Jinmao Tower is about 60m long and just 1.2m wide, unfenced by handrails, reported the official Liberation Daily.
Visitors could make rounds on the rim, lean off it or sit on its verge, while harnessed to an overhead rail system by a strong cable and wearing safety helmets.
They are also watched over by two safety instructors.
It costs 388 yuan (S$78) to access the skywalk for 30 minutes, with students entitled to a discount.
A maximum of 15 people are allowed on the platform at any time.
When the weather is fine, "skywalkers" would be able to enjoy the views of both banks of the Huangpu river as well as Chongming island off Shanghai, the Liberation Daily pointed out.
High-altitude viewing from mega-tall buildings has been seeing breakthroughs in Shanghai, said the newspaper, pointing to the transparent walkway at the Oriental Pearl Tower, which allows visitors to peer down from a height of 259m.
Another building, Shanghai Tower, is planning a high-suspension equipment that could extend visitors out from a high floor to more than 600m above ground.
That would top the 552m-high barricaded sightseeing platform it now provides.
