On Wed, 31 Jan 2007 09:57:12 -0500, in a place far, far away, "Jeff
Findley" <jeff.findley@xxxxxxxxxxxxxx> made the phosphor on my monitor
glow in such a way as to indicate that:

I was watching a show about building the new terminal for Jet Blue at JFK
Airport and one of the steel workers (a foreman?) said that once you go up
beyond a couple of stories, the difference in height doesn't matter much.
In other words, you die just as easily from a fall from three stories as you
do from 30 or 300 stories.

Terminal velocity is terminal velocity...

Actually, there was some interesting research done with cats (which
have a much lower terminal velocity than people). It turned out that
they were OK for short falls, or long ones, but those in between were
fatal. Short falls didn't give them enough time to build up a bad
speed, and long ones resulted in a relaxed cat at terminal velocity,
which was also OK. But the medium-height ones (I think from three to
six stories) were a problem, because as long as the cat accelerated,
it was freaking out, and hit hard enough to kill it without it
properly relaxing and being ready to hit the ground properly.

And no, they didn't do this by deliberately dropping cats. They did
forensics on natural accidents.
