Thanks to all who have responded so far, and especially thanks for taking this post in the spirit it was intended.

I was unusually grumpy when I posted the above; I don't know, but maybe my friend's death (presumed at this point; the search was called off without finding anything) affected me more than I realised.

Over the next couple of weeks, I'll be putting together my own thoughts on "Accident Avoidance for Dummies" which I would like to incorporate into the cadet "Flight Safety" proficiency in the fall. I'll probably post them in the other thread when I do.
