to do list


Seen on a WW2 sub at a submarine museum at Pearl Harbor. The diving officer would stand at his station and call back (through some kind of pipe) to each post to verify verbally that each hatch was closed, etc. This metal indicator panel was just a physical checklist for the officer to go through before issuing the order to dive.

Don't you hate it when you get ready to dive and there's just one thing you forgot to check? Kind of like thinking, hmm, did I turn off the iron?

I would improve the survivability of the device by making it so that you couldn't see the words "Rigged for diving" and"Rigged for surface" simultaneously. You'd only see the phrase which was true, like a big if-then statement.
