And there are still DC-3s working for a living around the world, the last one came out of the factory in 1945, THAT'S 70 YEARS AGO in case your are math challenged. it was designed by use of slide rules. I sat at the table for a deposition that had belonged to Donald Douglas around which slide rules had been furiously at work int the '30s designing that DC-3.
I heard a story that a DC-3 with 85,000 flight hours was still in scheduled passenger service. A nervous passenger asked "is an aiplane this old, safe?" The response, "how do your think it got to be this old."

I was reently contacted by a pilot interested in learning celnav as a backup since he is flying DC-3s over Antarctica, an updated model with P&W turboprop engines.
So, yaaa for slide rules!
