Don't know if any pilots reading this will have experience of flying in and out of Kigali, Rwanda. From memory I think I went in there with both BA and Sabena on a 747 and DC-10. Runway was at altitude and appeared to be built on the peak of one of the many hills. Now that was fun listening to the engines build and then going like the hammers of hell to get a fully laden aircraft up in high temperatures full of fuel for the trip to LHR or BRU.
