Given that his military experience is highlighted, it isn't too surprising that his course goes toward the battlefield survival end of the spectrum, which seems very popular now. I am more interested in "civilian survival," the situations that develop when your plane crashes, your boat sinks, your vehicle doesn't run, your feet won't work anymore, etc. Here there should be very little escape and evasion, and a lot of effort on being found.

As a participant in many SAR operations, I can say that most people would have been found a lot sooner, and some would have even lived, if they had even a slight grasp on survival principles.
