On February 14, 2007, 35-year-old Ewa Wiśnierska was preparing for the paragliding world championship in Australia. During a flight, she was lifted to an altitude of 32,631 ft and found herself inside a cumulonimbus cloud. She fainted because of the extreme cold and lack of oxygen.

After 40 minutes, her paraglider started to descend. She woke up when she was at around 23,000 ft. She managed to get out of the cloud and land safely on a small farm. She survived, though she did have severe frostbite.
