With regards to the CC. While there was no announcement of ditching, they certainly were aware of the situation and their surroundings. One stopped a passenger from opening the aft door, for instance. One was injured, but the evac went well and quickly-a real kudo for a situationally aware team.
Reading the NY blogs, apparently a number of pax refused to leave without carry-on bags. Some are seen on the wing with baggage. One lady refused to leave without her bags then blocked the exit with the bags after falling the water-those inside threw the bags over. She was pulled into a "raft". One wonders how well it would have worked had pax played by the rules.
With ditching switches relatively new and the F/O just out of of IOE, I suspect he didn't even think of it or get to the checklist.
