I looked for it but couldn't find it. One thread with 56,000+ posts.... like trying to find a needle in a haystack.
I'll see if I can find something on it Buckwheat. a better answer could have been given. all kinds of factors would go into I would guess. how he hit the water, the depth, what the bottom consisted of etc.
What I can see is Carr giving a time frame of 8:10 to 8:15. at 8:17 the plane is at the Columbia! the estimate was 5-10 minutes after the 8:05 mark. I believe Carr has even stated 8:20 which would put them over the "suburbs". we are now dangerously close to the Columbia by using the time data supplied on the transcripts. as I mentioned the other day. it could be as simple as being at the wrong place, at the wrong time.
Update: Georger Oct. 2010
Calcs show at a terminal velocity of 120 mph (53.6m/sec) Cooper in free fall may not have penetrated open water by more than 3-6 feet depending on angle ... and a mud base 16" thick no more than a foot again depending on angle ... all of which was a little surprising to me. I am using the standard formulae and estimated drag coeficients for water mud. The (low) terminal velocity of a human body turns out to be crucial vs say a meteorite, and in the case of mud a surprising amount of energy is dispersed outward quickly (even at relatively step angles).
This may give definition to the matter of
"augering in" which some speculated about.
In the water scenario it means that if he landed
in deep water he surely did not hit bottom, but simply suffered the usual injuries and moved on
with the current.
