I was lucky enough to fly on Williamson's DC-4 when I was working in Kenya. Somehow the folk group I was singing with at the time was invited down to Shinyanga for a weekend "entertaining the troops". Previously I had thought diamond mining was an old boy in a bush hat and a sieve. The Williamsons operation involved a fleet of draglines and JCBs. Very impressive. As aviation had cropped up in the course of the weekend and I'd met the DC-4 pilots, I got 30 minutes in the right hand seat on the return to Nairobi. Great times.
