After a huge gust of wind, two window washers were caught swaying and repeatedly smashing into the second tallest high-rise in Shanghai, China on Thursday. The incident occurred on the 91st floor of the 101-story Shanghai World Financial Center.
This is what the 1600-foot Shanghai building looks like from afar.
According to Travel China Guide, it houses offices, a hotel, museum, observation, parking garage and retail shops.
And the building boasts stunning views of Shanghai.
"I'm worried for them," an eyewitness said during the video.
