Flew into Goma at the height of the Rwandan crisis and having 1000's of refugees run toward my C-141 trying to score some food. I brought a case of Marlboros to pay the biggest guys to keep the majority of the refugees away.
Landing in Kigali during said crisis and having zero ATC, lighting, etc. A pack of wild dogs were living at the end of the runway were said to be feeding on the unfortunates that were recently killed and piled up just outside the airport perimeter. UN peacekeepers would periodically drive out and shoot the dogs to try to contain the spread of disease.
It was a colossal mess, but a few hours later we were kicking back and drinking beer on the beach in Mombasa. Very surreal.
