Yeah. Somebody who's really good at "tracking" (flying horizontally) can fall at about a 45 degree angle. So, from a couple miles up, ... Another thing not mentioned is that terminal velocity decreases as the air gets more dense. So, if you fall four miles, you can't track four miles -- the 45 degree thing is based on dense air.
