Terminal velocity is reached relatively quickly, in about 7 seconds IRC. You hit the ground at the same speed falling from a not so tall sky scraper as you do from the plane. Surviving the impact is more about position, which material you are smashing into, and if you hit any objects right before hitting the ground in order to break your fall.
