BOAC,
My point exactly. Prior to TV you are accelerating, 9.8m/s to the power of 2. If you were in a vaccum with no drag you would accelerate until you hit the ground. TV occurs because in air, at some point the drag or retarding force will equal the 1g acceleration due to gravity resulting in no further acceleration. i.e. constant velocity from then earthwards until you hit the ground. You will accelerate until TV is attained..
