That pic of the Hindenberg Wall looks like it was taken over Olsobip or a bit further up tucked against the wall over Bolivip. I lived in Tabubil in 1979 for 6 months, flying SEG after Kennecott and before OTML started. Only "outside" contact was when Dangerous Dave Merklin used to fly the weekly twotter from POM with our freezer. Special VFR up the Alice as only he could do!
