Flew into Luanda about 10 years back, we were supposed to fly south over the drink 10 miles out and fly an NDB, no hold to the runway. There was another aircraft just clearing to land and we got to fly around and get a good look-see at the countryside.
ATC screwed the pooch and cleared us to land while the other aircraft was still back-taxying off the rwy.
Hell if nothing less it is a story to tell.
Angola loves to blame the several russian aircraft that exist now in their dirt on mechanical failures.
