China gets 1100-ft high glass walkway without railing
The Jinmao Tower in the Chinese city of Shanghai on Thursday opened its 1,115-foot high glass skywalk, which does not have handrails, to the public. Visitors will be harnessed onto an overhead rail for up to 30 minutes, at the cost of $58. The skywalk is reported to be the world's highest handrail-free walkway.
