We had a run from Lagos to Jos in a Twotter, when sometimes you could get very strong winds. There you sat looking at a GPS speed readout of 130 knots as Nigeria crawled past, the River Niger, Bida, Abuja, the little railway station at the foot of the Jos Plateau, out in the distance Jos Aiport, just another ten or fifteen minutes to go now...
One I looked out the window to see a small, grey object flying formation with the Twotter. Yes, it was my brain, bored out of my skull. Thank God for the BBC World Service on the HF!
Going back to Lagos, 200 knots GS! Bwoah-ey!
Later, in the Dornier 328Jet I was feeling sorry for myself because it would only do .66 Mach, when that also seemed slow on a trip from Gao to Marrakech. It really is all relative.
