...Are you aware that... the initial wind chill factor was about 35 degrees F below zero and stayed about that until he hit the ground as a no-pull...
Can your prove that Robert? You seem to imply that the conditions were very stressful.
I know we've had this argument before, but since so many new sleuths are here, I think it is important to prove your statements.
To wit:
1. We don't know the exact wind chill on the aft stairs since the perturbations of wind around the stairs are not certain. Therefore it is hard to calculate the wind chill for Cooper while on the stairs. However, we do know that it was 22 degrees Fahrenheit at 8:13 pm at 10,000 feet, and that the plane was traveling at approximately 180 mph. But Cooper was not subjected to 180 mph winds due to the protection of the stair case.
2. If he jumped and went into a freefall, we know that for a few seconds Cooper was traveling at 180 mph once he left the stairs, but after about 15 seconds, according to Robb Heady and other skydivers, Cooper's speed through the air column would have approached terminal velocity, approximately 110 mph. So, the effective wind chill was cut nearly in half at this juncture. Then, if his chute was deployed he was traveling through the air column at 1,000 feet per minute, or about 20 mph.
3. But there is ample evidence from CIA training films to speculate that Cooper may have pulled his rip cord while on the aft stairs, suggesting that his movement through the air column was considerable less than 110 mph virtually as soon as the chute inflated and pulled him off the stairs. Afterwards, he would then be traveling at approximately 20 mph under a full canopy.
4. One way or another, Cooper was on the ground in ten minutes, maximum - perhaps much less if he was a no-pull. But, if Cooper was successful, what kinds of physical stress was he subjected to in the ten minutes he spent in the air/wind chill, under the known conditions?
