I was in error....seems that's what happens when I rely on memory. In the military, VNE was also INDICATED airspeed, not True airspeed. I just looked it up, and amazingly, it all comes back (however slowly). " VNE is the redline speed. This speed is found by dividing 1.4 beyond VNO to attain Vd. design diving speed.9 times vd= VNE. Vne is a constant expressed as indicated airspeed abd is not influenced by weight" Thanks for making me hit the books again...woke up a few brain cells. Sorry for mis-stating Vne as true. Should have been indicated.

That makes more sense to me. My understanding of the purpose of VNE, is that it is to prevent subjecting the airframe to excessive loads (or from becoming uncontrollable). At higher altitudes there is less air mass acting on the airframe and therefore less force. IAS is a pretty good indicator of the amount of force acting on the airframe.
