There are still a couple of air forces that fly C-46's and C-47's.
And there's a company, Basler, that's taking old DC-3s and really heavily modifying them...hanging a pair of turboprop engines on the wings, five-bladed props, stretched fuselages, all-new hydraulic, pneumatic, and electric systems. They're pushing them to Third World countries as transports, and in some cases, monitoring/ELINT platforms.
The DC-3 really is the airplane that just won't go away...almost everything else of its era is on the airshow circuit or in museums, but hundreds of those old Threes are still out there around the world, day after day, actually *working*.
