The idea was to super-cool the H2O and then repeatedly dip the end of a string into it forming an ice-ball much as one makes a candle. Once the ice-ball reached a sufficiently terrifying size - about 8" dia. - we used the shop band saw to cut it in half revealing very hail-stone like layers. We then showed this to Paul and his fellow scientists at the 'appropriate' time. When we saw the reaction was getting totally out of hand, we were forced to reveal our subterfuge. I don't think some ever forgave us. I was a grad student at NAU in Flagstaff at the time. We never saw any huge hail, but one day after the seeding we did get hail piled 6" - 8" deep all around the place. If I remember it was Vince Schaefer who had a big hand in the experiments. |

This is , after all, forum for glider stories
As I have not yet seen a glider story in this thread, here are annecdotes from a WGC. WGC Vrsac 1972. After the first day, the one decent soaring day, the airmass turned humid and cloud flying was the only way to make progress; a few pilots had oxygen and everyone had at least a T and S; I was really glad I had borrowed an AH since many hours were spent in cloud. Base was rarely above 2500 ft. AHungarian pilot wsa killed after losing control in a Cb; there was collision and lots of hail damge, holes sometimes as big as your fist. Nick Goodhart went to 30k ft in his Kestrel jut after the start, and flew the course and won the day in a straight glide; likewise on the penultimate day, which most people spent between 1000 and 3000 ft AGL, Witanen waited til a Cb brewed up near the start , long after everyone else had left, climbed high enough to complete the 200km course in one glide, the only one to finish. The last day was perhaps the stormiest, cloudb base 2000ft andv virually no lift below it. It was dark under the extensive canopy of Cb blowoff. Many pilots simply abandoned the task (a 200 km Triangle) After the start I ws able to climb to 12 k ft and head out on a compass course in cloud. I asked my crew chief to do DR based on zero wind and a 60 kt cruise; after some time I got a glimpse of the ground down a hole and saw a railway line which was right on the c course line; then I was in cloud again for 15mins and emerged from the side of a Cu at 3000ft 10km from TP 1, an airfield; there were a lot of gliders down there already, and after turning the mark and looking along the second leg into into a black wall illuminated with lightning flashes, I decided this was enough , threw awqy 2000 ft and landed, thankfull to be alive and undamaged after ten testing days. Several others followed me ! George MOffat was there too, we hugged ech other to celebrate survival. John Firth, an old, no longer bold pilot.

After the 1975 open class nationals in Hobbs, (which was know for being one of the wettest seasons in history) my father let me fly the family Kestral back home with another friend in his father's Nimbus II. We took off from Estrella, headed west for as far as we could get into California. A huge dust storm was rapidly approaching at Desert Center so my friends dad insisted we land immediately. We back tracked and landed as our crew parents were waiting for us on the ground at Desert Center. I rolled up to the trailer and the Kestrel being the big Libelle that it was, was in the box inside of 5 minutes. The Nimbus, with the extra wing pieces, wasn't so quick. We got the tips off, the tail, and the canopy just as the duststorm hit. Since we couldn't get the center panels of the wings off in time, we pulled the campers and trailers in front of the Nimbus to block the wind and six of us laid on the wing of the glider for 45 minutes as we literally got sand blasted. I'm not sure how strong the wind was but we were concerned that the campers and trailers could blow over on top of us.
After the storm had passed, there was two inches of dust inside our camper despite having all the windows and vents closed. It came in thru the little vents in the bottom of the sliding glass windows. We had to have the glass replaced on the camper because it was so badly pitted. I'm told there are still remnants of dust from that storm in the fuselage of that Nimbus, forty years later. Barry |
