aussiebum 1.5" classic

[Byron]

Sorry to confuse you - it is my ignorance to be excused (and I was also trying to recall La Paz Bolivia at high altitude).
The Lancastrian of British South American Airways crashed into Mount Tupungato in 1947, so it was in Argentina (it was on a flight from Buenos Aires to Santiago and was buried in deep snow in bad weather).
The story is fascinating and is called the Stardust crash but I guess that air accident investigation reports are only of interest to wonks like me (give me a PM if you have the time however - just a few details of date and airline for the Lima crash, so that I may read it up).
