If I actually was in that situation, I see two options:
1) Talk to someone on the radios, try to be a hero, and handfly the bogger.
-or-
2) Talk to someone on the radios about how to program the automatic flight system for a full autoland at the airport around with the longest runway/best rescue services/etc, let the automatics do the job, and let the purser/cabin crew chief organize an evacuation.
I like to think no 1 is more fun, but no 2 seems more reasonable.
