On Saturday John Simon went on final glide from a little over 45 kilometers out.
He had just climbed up from 2,000' to cloud base at 5,400' just north of the
Greystone airfield and told himself after a few turns near the south end of
Orange Lake that that was it, he wasn't going to turn any more.

His glide ratio was 41:1, including the portion where he pulled in to 50+ mph
airspeed to get down to goal.

Average ground speed was 54 mph with airspeed of 37 mph. The wind was 17 mph out
of the south southwest.

For the 37 kilometers that he flew under the two cloud streets without pulling
in to get to goal his L/D was 130.

Your L/D for the first 25km in 18 minutes was a whopping 293:1. At
one point on glide you gained over 600' over a 3 minute period going from 4931'
to 5580'. Another point of interest is that the cloud line appeared to be slowly
drifting eastward as you glided NNE to goal.

John Simon writes:

I could have gone quite a bit further. The only reason I lost any
altitude was that and about 2/3 of the way in the street ended and I had to
shift slightly NE to join it again losing 1000' and down to 4000' before I
rejoined and then I stayed there easily while gliding. I spent much time with
the bar stuffed trying to stay out of the clouds in the first section. In the
second section at 4000' I slowed up a bit.
