The Asiana 214 crash does raise some troubling issues as far as maximizing your own chance of surviving a plane crash are concerned.

None of the passengers had any warning prior to the crash so one minute you're chatting with the person next to you and the next minute your whole upper body is slamming into the seat in front of you at a high rate of speed. After landing, the pilots initially announced that people should remain in their seats so the eventual evacuation was delayed further. Three of the cabin crew were ejected out the rear, presumably leaving the passengers in the rear section without any crew to direct them. Two of the escape slides deployed into the cabin, and not outward, thus blocking those exits and immobilizing two more crewmembers. The 911 tapes seem to indicate that ambulances did not arrive for a signficant length of time (callers say "20 minutes" but not sure if their sense of time can be trusted), but it's not clear if any of the firefighters were tending to the injured or perhaps just to the most seriously injured because there were so many injured.

Not sure how much smoke was an issue before everyone was evacuated.
