Namaste VF,
thank you very much for this thread. I originally started backwards and then I realised I have to do it from the beginning. I've spent about 2 weeks with it.
OMG, you woke memories, especially your big photos of Everest, where a fellow climber of mine vanished after first alpine style climb of Bonnington route (SW face) in 1988. 4 folks been there for too long and after summiting they started to descend to South col. They talked with BC by walkie talkie and stated they had problem with visibility and exhaustion, one of them could hardly walk and in raging storm they vanished forever, probably descended by mistake into Kangshung face of Everest. This was one of the most epic climbs on Everest unfortunately with an tragic end.
Keep your posts coming, this is probably the best thread of PPRuNe.
