Help! We are deep into the bay at Davao, Mindanao...
*) We were spotted by some airplanes as we got a little too confident they couldn't see us

and of course they called in a nearby DD. Spend a couple of hours evading that *very* persisting DD. All cool and well!
Sonarman had reported "No contacts" for a while and I just wanted to have a listen myself - and there she was! Less than 5 nm away! Very loud and clear! Chocking!
In another life I learned zig-zagging to help sonar cover dead angles, so that's not the reason for the deafness. And we went from below 250 ft to 80 ft btw. so no scope viewing either. And no fatique, all men fresh.
What can we do? Call in Professor Rubini?
