Flight paths and meteorology

Richary - i think they head o/seas to africa - they usually fly extremely high altitudes - i c them fly over from time to time - also the jet-streams they leave behind (con trails) can be quite lengthy at such high levels.

That could be it. If I waypoint Melbourne to South Africa I get a bearing to start on at 225 degrees (roughly, didn't place the WP that accurately). Instead of the 274 degrees in a rhumb line (following the circumference of the earth which adds about 1000km).

Your spot on Big Pete. I flew on a flight from Sydney to Jo'burg and was intrigued when after taking off we headed straight down to Tassie. I seem to remember somewhere near or over Tassie we finally made a turn south west to west'ish. Makes sense when you look at a map of the globe - would cut a few hours and strong jet streams out of the flight. Coming home we didn't fly at such a low latitude - possibly to make use of the jet streams.
