As the person who originated this discussion (and also as
a person who spends a considerable time writing tutorial
articles and conducing workshops for beginners), I have a
slight problem with this comment.  

What tech info?

The discussion did not involve a single formula or any
number.  I mentioned earlier the pictures that I took from
the boat coming back from the Statue of Liberty.  As
I was mounting the the slides I was very disappointed seeing
one after the other picture fail because the clouds were
brought in front of the buildings, ruining the pair.  It is
good to know why this happens and how it can be
avoided, even if you don't plan to utilize this info.

Good for you!  Notice how you managed to sneak some
technical information here... like the fact that you held the
camera steady against the window and you took two shots
instead of just one?   How is this different from the person
who held his camera upside down?  

Hyperstereos from commercial airplanes are not a problem
as far as movement of clouds is concerned.  The main problem
is to find a good seat.  There are a few more issues too but
I don't want to scare people and prevent anyone from taking
pictures next time :)
