Remember those 30 degree up and down angles, and how you'd never quite be able to lean over far enough to touch the floor while keeping an erect posture? And remember how crap would fly out of the damn'dest places after an upkeep? And remember how you never ever slid down some long straightaway on a grey blanket, like the Missile Compartment on a boomer or past the starboard side of Maneuvering in a 688? Ever wanted video proof that, yes, you did lean that far over? Check out these guys from what looks like a Trident (bad word warning!) doing a 29° up-angle:
Good times...
Update 0100 12 Sep: Here's another one -- not quite so dramatic -- that looks like it was taken in Crew's Mess on USS Alaska (SSBN 732).
