Hi Mike, Yeah, I tend to agree with you. This is classic glider lore, that we were all taught in the cradle.
Somewhat related are those "impossible" final glides late in the day, which were achieved by following highly vegetated creek lines. Of course a big "creek" like the Murray River, gives you more of a sporting chance. I "sort of" remember a flight that was done many years ago by our old mate Noel Roediger, out of Benalla. I think the last turn-point was Shepparton A/F. Noel used the late evening "lift" off the Broken River, to win the day. He was in fact the only pilot in the competition to get home that day. I wonder if Noel remembers that flight? From what I can remember, it should be etched in his memory forever! My (fallible), memory says that over the last 50 k or so, Noel achieved a MAX height of around 2000' AGL. I think that we can assume that there was a high "pucker factor" involved here, and no doubt Noel slept well that night!

Subject: Re: [Aus-soaring] Cloud proof fence Matthew, Here's the link to the actual paper. There are others in the research repository. Search for Lyons,Nair http://researchrepository.murdoch.edu.au/4041/ This is a climatological study. I think the clouds on any given day over the scrub may be for other reasons. Particularly late in the day the scrub will trap warmer, moister air (tree evapo-transpiration - it's what they do) which will become lighter than the air over the open country nearby at low level leading to late convection with high based cu.

Often I've seen cumulus form over the sunset country but not elsewhere when flying out of Waikerie or Horsham. Apparently it's not a coincidence. _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring Borgelt Instruments - design & manufacture of quality soaring instrumentation since 1978 www.borgeltinstruments.com <http://www.borgeltinstruments.com/> tel: 07 4635 5784 overseas: int+61-7-4635 5784 mob: 042835 5784 : int+61-42835 5784 P O Box 4607, Toowoomba East, QLD 4350, Australia
