It's 3 AM ET and dawn is breaking over the Western Sahara.
We're being treated to a 60-min pitstop in Dakar, following an unremarkable 8.5 hour trans-Atlantic flight. Approximately 50 people departed and others boarded. Another 9 hrs to Joburg. I learned later from a South African Airlines (SAA) pilot that the planes make this stop only when warmer temperatures in departure cities prohibit loading enough fuel to make the trip nonstop.
I'm running a GPS logger on the flight (don't tell SAA), which captures speed, altitude, and bearing, as well as coordinates. Will run it on the trek, if it works.
