Why one keeps the canopy closed and the wings tied down in the afternoon. http://www.youtube.com/watch?v=bCGUE...arch=parapente Last spring, a student of mine was concentrating on his aim point while flying final to Boulders glider runway. He was concentratng so hard he failed to notice a small vortex ruffling the water as it crossed the lake at the approach end. It looked like out glide path would intercept it. I casually said, "My extra sensory perception says we will hit strong lift in a few seconds". This just got a grunt from the front seat. When we hit the thermal, it bounced us up about 100 feet, vastly complicating the students landing approach but he managed to stop at the far end of the runway. I walked away as the line boy and the student started pushing the glider back to the start point, but was still close enough to hear, "How the hell did he know that?" I'd explain it later - meanwhile, anything to get respect. Bill Daniels |

However, if one is not near the ground, dust devils can be quite useful. On
Saturday I spotted a big one like in the first part of the video. The "dust" part only went up about 300' AGL but the rest of it took me in a Grob 103 from 3000' up to 9000' MSL. Nice!

Check out the dust devils on Mars. Some estimated to be 30 km high!
