i’m pretty sure there’s a few C-47s still out there in service
That plane was in the air for about 16 years.
Very few with piston engines. Most DC-3s have been reno’ed and turboprop added, from what I understand.
It is funny that you mentioned a C-47 / DC-3. As I was driving by YYC around noon, I saw one of Ken Borek Air Ltd.’s Turbine DC-3s coming in for a landing. I haven’t seen one landing or taking off in a very long time. They are very busy, just I’ve not been up by YYC when they were taking off or landing.
