Pga. en [[tordenstorm]]s voldsomme statiske opdrift<ref>[https://www.theweatherprediction.com/habyhints3/957/ theweatherprediction.com: HOW DOES DYNAMIC LIFT COMPARE TO CONVECTIVE LIFT?] Citat: "...Dynamic lifting is a forced lifting of air. It is much slower than convective lifting but over time dynamic lifting can produce a significant amount of vertical uplift...Convective lifting is air rising due to positive buoyancy similar to the process of how a helium balloon rises quickly into the air since the air in the balloon is less dense than the surrounding air. This mechanism of rising air is very quick. Thus, convective uplift often produces thunderstorms while dynamic lift produces light to moderate precipitation...", [https://web.archive.org/web/20190708073231/https://www.theweatherprediction.com/habyhints3/957/ backup]</ref> i det østlige [[Australien]] blev den 35-årige [[paraglider]] Ewa Wisnierska suget op i ca. 9.940 meters højde, fra ca. 800 meters højde (gennemsnitlig 10 m/s; 36 km/t), i løbet af ca. 15 minutter med [[lyn]] og torden omkring sig og mistede bevidstheden i 30 minutter – og overlevede. Hun var blevet overiset, men formåede efter at være kommet til bevidsthed i ca. 500 meters højde, at lande og derefter kontakte sit team. Hendes højde (og position) blev målt med [[GPS]].
