Just now I was gobsmacked to learn that the SAAF is still operating DC-3s (well, C47s, whatever), after reading the sad newsthat one of theirs had crashed. This led me to checking out who else is still using them - and what better way than the Wikipedia list of incidents and accidents?
It's an interesting list: old warbirds, feederlines, under-financed and over-coked cargo charters, Antarctic supply, and - especially in Africa - the poorer relations of the missions and institutions that Alex has been plotting for years on the Viktorfeed. I was struck by (a) it's the periphery, however you care to define it, and (b) there's lots of it, nearly 80 years since the design was a gleam in Arthur Raymond's eye.
David Edgerton's The Shock of the Old is not a perfect book, but it's the best one that I've yet seen for hammering home this fact: technology, especially ubiquitous technology is old. Often very old, and increasingly, far older than us.
