Saw this picture over at NavSource, and it reminded me of one thing that I don't miss about submarines:
It's a picture of the Ship's Control party of USS Nebraska (SSBN 739) during some sort of drill requiring EABs (probably a fire drill). One of the things I hated most was coming to PD while wearing an EAB -- you really couldn't see out the 'scope at all, plus you got maybe 1 1/2 revolutions before you ran out of EAB line and you had to reverse direction. It's definitely something for the younger guys to do. (One of the best things about being Eng was that I was almost always a drill monitor, so I hardly ever had to wear the EABs.)
On another, more serious note, the NavSource site recently added some great drawings and pictures of the older pre-Holland submarines with lots of great background information. Boats they have there include American Turtle, Alligator, H. L. Hunley, and Intelligent Whale. Some good stuff for submarine buffs!
