Maybe it is fake.
A fall from 800 meters is high enough to reach terminal velocity. Adding another 9,100 meters isn't going to increase the speed of impact any.
Yep. In a flat stable position a skydiver will reach terminal velocity in 12-15 seconds ish. 120 -126 mph. I have personally done 195mph curled into a ball. Quite a rush coming out of that back into a flat position then doing a few somersaults for good measure. Head down can be much faster. If memory serves me correct the world record was set by an american airman called kisinger who went upto 93,000 sat in a chair on a balloon. He released and fell for 4 minutes hitting speeds of 600mph+. I may be a bit sketchy but the figures are about right.
The article presented suggests that this woman was unlikely to have been travelling at such speeds due to the resistance that the equipment around her would have had. Not only would this have slowed her down, she also apparently hit the ground, which was snow, at a sharp angle. Not sure if this actually has any relevence to the arguement raised re 70th floor etc but i would suggest that anyone jumping from the 70th floor without any means to slow themselves down wouldnt stand a chance if hitting a solid concrete surface. Sorry .Horrible thought.
I am aware of skydivers who have had double malfunctions at 2,500 - 4,000ft. Both parachutes have failed to deploy correctly or one has entangled the other and is just a withering 'washing bag' above them. Scary stuff. This has however slowed them enough to actually survive, often with the additional good fortune of hitting trees or buidings which has also cushioned the fall. They are usually in a mess but have survived. No parachute to speak of -then no chance.
