Yes, the first-hand stuff is most valuable. I'd look at it in a couple perhaps non-obvious ways - partly because any actual situation is unlikely to be just the same - heck, even in this one, different people probably coped differently.
And of course, that nasty reality - many failed to cope - would have to be dealt with.
So to me, the take on how humans reacted, and what turned out to be really important was the key - some things would be a little different - a lot depends on the speed with which the S is flying and the RPM of the fan - but a lot is universal "stupid human tricks". Other humans will probably be the main make or break variable once the basics are otherwise taken care of in preparation, so that aspect is way worth study.
And as DoChen quoted - "Going into a fight everyone has a plan. Then you get hit."
An awful lot of this stuff is pure fantasy. This link had me rolling a few minutes ago:
Ok, stashing booze - for dual use seems obvious enough. But Bic lighters as a primary trade item? Not so much a thing I've thought of (but I always have a bunch of ways to make fire due to my normal setup), but it makes some sense in a crowded situation.
A lot of the first link reminds me greatly of a bunch of stories written by Robert Heinlein in the 40's and '50s about "after the big one" or "after the US is occupied" which he spent some time on. Man, that guy was as prescient as they come. Those would seem useful, as they seem borne out by real-world experience at this point - he makes many of the same points (and some new ones), but much more eloquently, looks at the ramifications more throughly.
