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.
And the building boasts stunning views of Shanghai.
"I'm worried for them," an eyewitness said during the video.
Several news reports said rescue workers smashed a window on the high-rise to free the workers, who were shaken up, but not injured.
