Guests at a Chinese ski resort recently went through a traumatizing experience.

The South China Morning Post reports that a chairlift stopped rapidly due to a malfunction, leading to the chairs rapidly swinging with passengers onboard. The ski resort wasn’t specified by the Post, but it’s located in western China’s Xinjiang Uygur autonomous region. The resort was able to safely evacuate everyone that was on the chairlift. The ultimate cause of the malfunction was abnormally cold weather.
