The vertical extent of a cumulus cloud is a Gliding, and sailplane flying where pilots experience significant liftĭue to a thermal under the base of cumulus clouds, especially toweringĬumulus and cumulonimbus. If you want to know how people get trapped and about emergency procedures for escape, then I suggest you Google "cloud suck".Ĭloud suck is a phenomenon commonly known in paragliding, hang His frozen body was discovered later and returned to his Both gliders lost consciousness above 30,000įeet, one, happily, was released by the storm, and regained lucidityīefore crashing into the ground. In one reported incident, two hang gliders were caught in cloud suckīy the same storm clouds. Here is a claim that it can happen to hang-gliders as well but there is no reference to back it up. See under Wind penetration where my above suggestion is supported. Advanced wing - 16 mph, to over 100 mph which has been clocked in speed gliding competitions Hang-glider Beginner wing 14 mph to 45 mph. They should be able fly out of it provided they can keep a sense of direction. Hang-gliders are likely to find it easier to escape a storm because their forward speed can be much greater that that of a paraglider. Here's another - this is a good one because it is videoed with a live commentary from the pilot who escaped the updraft before it was too late.Ĭaught in Cloud Suck! - Life lesson from 3Km above sea level Unconscious and wearing a layer of ice, to an altitude of more than (I'll see what I can find for a hang-glider)Įwa Wisnierska was sucked into a powerful thunderstorm while trainingįor the world paragliding championships in Australia. This can happen even to experts if they are incautious enough to take risks with the weather. Getting caught in a thunderstorm is the most likely cause. It should not kill the pilot - if you can plausably argue a volcanic erruption - then fine but the pilot must survive (unconsciousness is just fine though).Īny landscape type can be specified in supporting arguments within the answer, sea nearby, desert, mountains, geisers, volcanoes, icefields - anything that could feasably contribute to the desired sudden lift.Ī hang glider, the pilot taken by surprise, there is a sudden unexpected lift to 25,000 feet altitude, what could do this? I need the ascent to be sudden and unexpected (for an arguably inexperienced pilot), be it meteorological, geothermal or by some other (not fantasy) means. This slow and steady way is not what I need. I'm aware that over 38,000 feet has been achieved by exploiting thermals. It's not relevant to this question, but for anyone who's curious this was the first, this the second.Įarth-normal atmospheric pressure/content. This is the third in a series of 5 (at this point) questions.
