I wear boots, wear a wilderness tactical belt. I carry MRE PB, hard candy, Jerky, and a pocket guide of the SAS survival guide, I usually fly with a book or two, one novel (this trip is a re-read of Deep Winter), one other (this trip is root cellars and cold storage). I also carry a single cell CR123 light (fenix PD20 is my go to), a few spare batteries, a AMK pocket survival kit (xacto blade removed), light my fire army rod or a mag block (weird, I have been on dozens of international flights and enough domestic flights I stop paying attention and have never been stopped for this... but I have been detained for the surefire spares carrier a few times, 1 girl thought it was a revolver part, another guy a grenade??? WTF) Even if I get stopped they can toss it, they are cheap. I also carry a nomex balaclava and flight gloves. Odds are if it crashes, its going down hard and no one will survive, but if one were, hopefully the stuff will help them or me. But a commerical airliner without power could drop 1 foot for every 2 feet forward it moves, so it really is FALLING out of the sky. But still if there is hope... In a few hours I will be in the air for a short 3 hours trip, then a 2 hour layover to a 14.5 hour trip.... cant wait. Atleast I got better seats this time.
