Subject: Re: [Aus-soaring] Club Class Records: unofficial
This really was a special run of weather. There were several great days in a
row, but the last was the best as far as Temora went - and it was the only day
I didn't have to work. There were at least four 750km flights in club class
gliders on that day - Ziggy Kominek in Jantar Std 2 CQT, Col Vassarotti in Std
Libelle BE, Gary Stevenson in Std Libelle BL, and myself in Std Cirrus AM. I
think David Pietsch may have done a 750 also in ASW20 ZZ (not sure it was known
as ZZ then) although at the time the 20 was a bit above club class.
This was the same day that Tom Claffey set the Std Class Australian record for
a 1000 (1016km) FAI triangle speed in Discus B FV. Gary and I did
Temora-Hillston-Narromne-Temora - a 750km FAI triangle (756km). Mine was
memorable for several reasons - a 12:25 launch after rigging with an optimistic
750 in the little black box, then cruising at 100 knots in a Cirrus to stay out
of the streeting cloud at 11,000 ft on the first leg to Hillston, passing Tomas
Suchanek and Tom at Forbes on the last leg (they were en route to Narromine),
landing after 7:02 (107km/hr)......it was an awesome flight. 900 was possible
in the Cirrus that day. Gary may recollect it too.
I think that that may have been they weather cycle that got Harry from Keepit
to Gawler, but not sure.
The spoiler was the tug release point for me was on the wrong side of the
airfield (en route) so I was never able to claim it. Oh well - I'll claim the
750 when I do my 1000 I thought. Never got there despite many attempts over 10
years (in Discus A D1 - best 925km but not claimable either due abandoning 2nd
turn) - just needed that magic '99 day again. I watched weather closely whilst
juggling work commitments (which as a water resources engineer also allowed me
to get paid for weather watching!), but never saw a day lke it, so I don't
subscribe to the 7 year cycle!
Cheers
