Gino, thats brilliant. Not only have you supplied an interesting snipet, I now know what to search for also
Just that one log of 7 patrols tells a story. It looks like the japanese really tried to fight back, but a lot could also be where the submarine was operating. I guess if someone went to the effort, they could build a pretty good picture form logs like this, with corresponding patrol zones + times/dates.
Still, meeting over 170 aircraft contacts in an 8 and a half week period is a LOT. I bet those guys really valued the SD radar
