Also I love that it breaks down to like

Japanese Navy: [complicated math]
America: WHO WANTS TO PLAY A BEEPY GAME OF MARCO POLO

(not JUST the Japanese, since this was early in the history of aircraft carriers, but at the time I think the only three powers WITH aircraft carriers in use were US, Japan, and the UK. Though I'm not sure which side of this divide the latter fell on)

(Germany had one but it wasn't actually used for anything but propaganda and testing)

also I cannot imagine trying to navigate via dead reckoning and memory while trying to keep a possibly damaged plane in the air over the ocean with a complete lack of landmarks

just let me crash into the sea at that point, I absolutely will not solve for X
