"Paddles" On A Submarine
When I did a deployment on USS John C. Stennis (CVN 74) in 2000, I learned a lot about flight deck operations. One of the things I found most fascinating was the job of the Landing Signal Officer, or "Paddles" -- the officer on the carrier deck (actually in a bunker) who helps the pilots land. I always figure, "Well, there's one job a submariner will never have to learn".
How times have changed. Here's a recent picture from USS Ohio (SSGN 726) that shows they have their own version of "Paddles":
Other pictures of the helo PERSTRANS are here and here. Having an inordinate fear of getting shocked, I'm glad I never had to be on the team that received a transfer from a helicopter.
