That was the fully battery life, time for a 48 hour recharge.

I just found my fathers pilot log from 1940 when he was apparently upgrading his license. About 90 hours logged with lots of pylons, spins, stalls, etc. He eventually had multi-engine land and sea rating and was part owner of a C-47.

Interesting that some of the handwriting looks like mine, but I wasn't exactly around in the 1940s.
