Cairo is a long, long way from the great circle route between London and Joburg. I understand that there aren't a whole lot of welcoming places if, say, you're over the southern Sahara, but still, I'd estimate that CAI is going to be at least a 1000-mile diversion from most routes.
That's also my initial reaction...
Anyone would care to describe the standard route between London and Joburg ?
Also what was their approx location when they elected to divert... ?
Something doesn't add up in this story
