Above all, rely on your inner resources and think positively. Although the U.S. airline system is the safest in the world, crashes do occur. However, nearly all crashes have survivors. Do not depend upon others. You are your own safety officer.
Survival favors the prepared.
Wear natural fibers. Synthetic clothing, including nylons, burns right through the skin causing severe injury. If you are wearing nylons and have to slide down the emergency chute, the friction could melt the material into your skin. Wear bright colors. You can be seen better if you need emergency treatment outside the plane.
