During the Pacific war Japanese and Alied carrier aircraft had millions of square miles of empty ocean to fly over, usually spent looking for each other's fleets. I know they had the usual map and compass and that was usually about it for most aircraft especially those with one man crews...i want to know how did they navigate accurately back to their carriers in all that ocean? What if they got lost in overcast or at night and couldnt even see the stars to navigate by? Could the carrier help them find their way back? Anybody have any idea of the numbers or percentage of carrier aircraft lost simply because they could not find their way back to their carrier?
