Reminded of an incident some years back while operating in DCR with a KingAir.. inbound to Lubumbashi from Kisenge... normally straight in on R07 was told tersely by the tower to land on R21.. when queried got not response other than even more tersely "LAND R 21!" then a few moments later was asked if I could make a short landing (on if I remember correctly an 11,000 ft runway with a B200).. approaching the downwind we saw why.. a DC8 had crash-landed following an hydraulic failure and was strewn down almost the entire length of the runway. Hey.. this is Africa.. no reason to close the runway just because a DC8 had crashed on it..
