Great info, Thanks for sharing this. I have been considering how much survival information, and cheap consumer goods passed off as survival equipment actually proved its worth when put to the test.

Case in point, for an average survival kit, would pen gun aerial flares be of any value compared to say 12 gauge aerials? I had not been aware of any serious consideration of such things.

Not to mention, lots of other items should be evaluated on a scientific basis as well.
