but not after he entered full atmosphere
fluid that high is less dense = less air resistance

I actually want to write a function and plot it, would you know if there is a a known coefficient of drag for a human?
NVM found this [TABLE="class: large, width: 670"]

because you would eventually slow to the other terminal velocity before you hit the ground

I would accept that as a lower limit ... cn

I'm guessing you wouldn't feel it except as a very slight increase in perceived gravity. The thing about free fall (and all flight) is that one's sense of altitude has to be "trained in" as we learn what to use as scale objects. cn

Well considering the main goal was the height and not speed, I'm sure they took that into consideration, doesn't change anything tho.

I was referring to surviving a fall from a certain height.
I wonder if he could see the shock wave being pushed by his visor that would be bad ass

Almost certainly not ... the air was too thin and dry. The only real way to visualize mild shock waves like that is by specialized photography (Schlieren) or by their effect on a nearby surface. cn

Well here you go guys i hope you enjoy it. The temperature change with altitude was not nice or even a real function for that matter. Everything was related to temperature, Pressure,density, ect .
Forced me to solve a bunch of 2nd order differential piecewise functions
The max speed for my estimate was about 400 m/s or 900mph
Not bad considering I took an average mass for a human and projected cross-section.

You can see that initially he accelerated very fast reaching his max speed in only 15,000 meters in. after that the air begins to get dense and air resistance starts to take effect.
not perfect but its what I do when bored

Thank you for that, Ryan!
I encountered this during an earlier search ... the shapes are a bit different, but not hugely imo. cn
