Elsewhere on this thread there is a link to the ex-RAF Argosy that ended up on the Zaire (9Q) register.
Whilst unloading freight at Lubumbashi in around June '79, I went on board - the crew offered a brew, facilitated (if memory serves correctly) by starting up the aeroplane's APU.
It certainly had a fixed nose and I seem to recall glass panels below the nose. There to allow map-reading for the Nav? spotting the drop zone for the loadmaster/troop despatcher? Someone here will know for sure!
I have a feeling the aeroplane was U/S, damaged in a hard landing. I don't think it flew again.
BSD.
ps - it could have been Goma instead of Lubumbashi and maybe we were uplifting, not unloading freight (Cobalt?) Alas, memory fading.
