Default Bullets falling back to earth


I understand that the terminal velocity of a spread-eagled human is
something like 120 mph. It doesn't matter if you fall from 2,000 feet or
50,000 feet, you hit the ground at around 120 per. Does anyone have better
data on that?

120 mph is about right... you can vary it a good bit by body position
though... maybe 110 or a little under by 'getting big', and push 200 by
getting vertical and 'small'.

As I recall, it takes about 11 seconds, and 1,300 feet to reach terminal
in a relaxed 'frog' position. (This is what I recall, don't hold me to
it, if anyone's interested I'll look it up in some old jumping books.)

There is a rec.skydiving newsgroup too... mostly shuck & jive though.

Skydiving is about all I did in the 70's... it's a lot of fun really.
Most of the he-man super dangerous aspect was pretty much gone by the
time started, and they've come a long way since then.
