I flew as a passemger on the China Clipper - exact route noted by Billy the Bus.
An amazing plane; fold-out overhead beds (where carry-on is now stowed) and a lower "basement" cocktail-lounge in the belly. Our flight was on a Boeing Stratocruiser (civilian B-29) It needed the comforts - the entire flight took about 36 hours.
My first thought was of course this - Alameda is a U.S.Naval Air Station with beacon and weather reports.
