After seeing the movie "Alive" as well as reading the book, I made a point to carry various snack foods with me every time I flew. I usually pack enough food in both my carry-on bags to ensure that I can endure the hell of crashing and subsequent waiting for rescue.
If by some chance I exhaust my provisions and still find myself "pre-rescue", I have made a contingency plan:
I'd eat (in order of precedence)
1. Eat the Flight Crew first. It's their fault I'm here in the first place
2. The folks in the middle seats that always seem annoyed with you whenever you ask them to move in order for you to get in or out of your seat.
3. The passengers who can't seem to put down their cell phones until the very last moment when the door closes or when the stewardesses tell them to knock it off. "Can you hear me now?"
4. The slackers who think they're at home and proceed to take off their shoes, examine their feet, clean their toenails, fart, belch and forget that other people on the plane know how to act in civilization.
Of course, the list could change as my mood changes.
Lastly, if I'm ever on a plane with you guys and we crash. I'm giving you guys permission to eat me. That's right. You can eat me. The only thing I will caution you is that some parts are a little fatty so if you do care to partake of my generosity, please remember to help yourself to only one serving per day. I'm not sure of my nutritional value, but I can tell you...it's not that good.
