Can anyone confirm the route flown by the Argosy ? I recall looking down at pyramids enroute, perhaps Sudan ? I expect that diplomatic niceties may have resulted in some odd routes.
We used to fly an almost straight line across the eastern edge of Kenya, then over Ethopia to Djibouti and on to Aden. Flight time was five hours plus or minus five minutes. No diplomatic clearance problems and nowhere near the Pyramids in Cairo!
