I have came across this answer, about PanAm's first trans-Pacific flight (SFO-MNL route via HNL, MDY, AWK and GUM). For the text, I'm working on, I was wondering, if there is any source that can provide more information on this route.
- years of operation,
- approx. times needed to flight each segment,
- approx. break times (refueling?) times at each mid-point,
- was passengers allowed to leave the airplane during each break?
I'm also interested in getting answer to a question that might be harder to answer (too broad?). How it was possible to service / refuel airplane on airports marked as uninhabited in the original answer (MDY and AWK)?
