McCoy/Kirk in shuttle crash

I'm looking for a fic from a while back. What I remember is Kirk and McCoy were alone in a shuttle crash. They crashed in water and it's slowly rising inside the shuttle, and McCoy is pinned. Can anybody help with finding this one? Thanks.

I think this the one you're looking for
