I'm looking for a copy of the article (with figures/graphics) titled

Weather Conditions in Southern Africa for Long Distance and High
Speed Soaring Flights or
The "Magic" of the Trough Line
by Helmuth Fisher

Using Google I've found copies of the article WITHOUT the figures/
graphics on www.gariepgliding.com and other sites, but am looking for
a version with the figures.

Pointers to other good articles addressing the best places and times
of year to fly in the southern hemisphere are also welcome.

Thanks in advance for any help!
