Wow...that's interesting. You mean near-space is *different* from being on the
ground? <giggle>

Seriously, thanks for the enlightenment. This stuff is
*interesting*...presumambly the drag is not *independant* of the spacecraft
attitude. But you have to wonder if it acts with any kind of moment arm,
exerting a turning force that would interfere with changing the attitude...sand
how that force would vary with attitude.
