Navigation in the 1930s
Sorry but also slightly off topic.
When the Southern Cross departed Oakland heading to Hawaii on the Pacific run, I believe navigator Harry Lyon used naval or marine maps for the navigation.
I also read something about using a ‘beam’ as they left San Fransisco for navigating the first leg. Does anyone know what that would’ve been in 1928? Trying to recall what I read but they lost it around 400 miles (not sure nm or mi) out. Then used various ships along the route to assist. Along with the sextant for fixes. Hazy memory sorry. I’ll need to dig up my book I have.
The actual maps are available to view online from a government library in Australia. Quite amazing to look over them.

I believe Chichester devised tables enabling him to use a nautical sextant at altitude, I believe those tables are still in use. Chichester was a cartographer by profession.
