I've landed at Wau in a DC3 on the TAA PWL (remember those bloody flight numbers with letters!!) service - with my wife of 24 hours. Honeymooned at Pine Lodge Hotel, Bulolo when Ferris? was the owner. Top spot.
They were still dragging gold out of the place and BGD gold smelting room would be a security man's nightmare. It was in the middle of Bulolo village (town?) guarded by chicken wire!
