As a professional international pilot of large multi engine turbine aircraft...
1. "Dress to egress." Wear a jacket. Wear shoes and not flip flops. I'm not even just talking about crashing. What are you gonna do when your balmy trip from Phoenix to Miami gets diverted to Chicago? And I really mean "dress" to egress. Not "pack" to egress... Keep it on your person.
2. You won't need to be "surviving" if your plane makes a forced landing. It's more like getting quickly outta the jet and then waiting. In the US (or anywhere else with radar coverage), on an IFR flight, ATC will know that something is wrong well before you make it to the ground. Just get off the jet and wait for your ride. If you are outside radar coverage (parts of the Atlanic or Pacific Oceans and Africa), on an IFR flight, ATC will STILL probably know that you are in trouble before you make it to the ground. Even if they don't hear about it before hand, ATC will know in 20-30 minutes when your jet misses its report. You're ride is coming, it just might take a few hours.
3. All the survival gear you need is on the jet. Follow the instructions of the crew silently and calmly. When we tell you to take your seats and we ask the flight attendants to prepare for landing, we don't need you jumping up to grab your compass and matches. The same thing goes for when you are getting off the jet. LEAVE YOUR BAGGAGE ALONE.
4. If it makes you feel better, keep a flashlight in your pocket. Or wear one of those 550 cord bracelets.
Above all... DRESS TO EGRESS!
