The 1958 WGC Open Class was won on a day like that, except
that
E.G. Haase (as relayed personally to me) made a string of very
low saves (albeit all over very landable terrain) and was thus
able
to tiptoe his way to victory that day. He was then able to defend
his
lead until the contest ended. It was a brilliant flight, not luck.
Some
pilots are just better at that kind of flying than others. For
example,
in Belgium, they have a maximum altitude of 3,000' due to
controlled airspace over the entire country. Those guys fly low a
lot.

Did he mention his thermal detector?! This is pretty good stuff,
especially the last two paragraphs. The good ole days

Thanks for the link. No, E.G. never mentioned the thermal detector
to me. He talked very extensively about the HKS-3, and what they
did to tune it though. They used wing warping as opposed to
ailerons in order to minimize interference drag. The canopy
didn't have a vent or window so as not to disturb the air in front
of the wing root. He had a vent air exhaust in the tail-cone, but
could only get ventilation air through a scoop in the wheel well
when the gear was down. So, he generally thermalled with the
gear down for cockpit ventilation, and cruised with the gear
retracted. He said that everyone thought he was crazy to
always thermal with the gear down, but that was his only access
to fresh air as the rest of the glider was sealed up so tightly. He
told me to always have a vent air extraction exit that was 50%
larger than the inlet vent so as to prevent positive pressure
buildup inside the glider.

That was back in 1972 when I was 21. I stayed at his house as
a guest for ~a week, and flew with him and his club in Vogtareuth
Germany. I even became the first person other that E.G.
or his partner allowed to fly his ASK-14 motorglider. I think I
logged about ~20 hours flying in the German Alps with it. Those
were very good times for me...
