Subject: [NavList] "Time and Navigation" presentation
There's a recent presentation on the topic of "Time and Navigation" by Andrew Johnston of the National Air and Space Museum:

Perhaps nothing really new for Navlist readers, but the photos are very good---there's an interior view of the Apollo sextant on page 21, and page 15 shows a certain "Fairchild-Maxson Line of Position Computer (1938)", looking for all the world like a modern ruggedized electronics enclosure, but with some sort of geared mechanism inside. The line drawings remind me of Sam Brown's work (the Edmund Scientific booklets, the John Strong books, etc.).
Other papers in the same session (future of UTC and leap seconds):
