In order to not highjack another current thread on aviation survival kits, I've opted to start a new thread on surviving the initial crash. If you don't survive the initial crash, what kit you carry is a moot point.

A very interesting link to start from is "How to Survive a Plane Crash". This link is aimed primarily at airline passengers. Some years back I attended a training on escaping from a helicopter or light plane, including dunker training. It is interesting that in general the linked article covers the same principles.

In general:

1. Even before take off. think about and plan your exit (Including alterates). Assume you will need to exit with little or no visibility.
2. Always try to maintain situational awareness.
3. Keep your seatbelt or harness fastened, snugly.
4. Assume a crash position.
5. When the aircraft stops moving, follow your plan and GET OUT FAST!

Alaska has a very high incidence of light plane crashes. While many people die, a lot of people do survive. If I get time, I may post some links to examples later.
