FRIDAY,
Another person just like me (DC-3 obsessed). The DC-3 owned by Phoebus Apollo is for their charter operation. I don't think you can buy hours on it. If you are really interested in flying the Dak and have £17000 to spare try
South Coast Airways. Alternately,
Tyler Aviation run a first officer program where you pay to fly the Dak commercially in the Caribbean. Packages start at 10800 USD for 250 hours. I wouldn't normally advocate working for no pay, let alone paying to work but I might be tempted to make an exception for the Dak.
Bob,
Sorry, drifted off topic slightly. Back to the hour-building in SA thing. Try
Flight Training College of Africa. Not sure if they allow twin hire though. Single is about £55 ph, and the scenery is beautiful,
