Maybe I'm being too simplistic, but it seems to me that what Robert
is looking for (Robert can speak for himself better than I, but I'll
toss in my $0.02 worth anyway), is data from a free-falling object
that covers enough time to show the effects of air resistance,
perhaps even terminal velocity.
I suspect that it might be difficult
to come by, but how about generating some of your own, by videotaping
an object (a basketball, say, being dropped from the top of a four-
or five-story building.

I have to agree with Hugh here. If the purpose is to determine the
velocity-dependence of the drag force--as I suspect it is--it will be
difficult to come by data that is accurate enough.
There was a
thread on this in December 1997 that may be reviewed at
http://lists.nau.edu/cgi-bin/wa?A1=ind9712&L=phys-l&D=0#95
(BTW, the review is made needlessly difficult due to the fact that
various contributors used the subject headings "air resistance", "Air
resistance", and "Air Resistance" which are all considered to be
different threads by the archiving software.)
