[DeTomaso] a arms

I thought there was consensus on the list that the movement of the tufts 
along the side of the car implied that the boundary layer was minimal to 
non-existent.  The tufts appeared uniformly pointed toward the rear of the 
vehicle at all speeds.  Others opined that if a boundary layer existed, the 
tufts would be moving every which a way to one another.

Did you interpret the data differently or not have the opportunity to view 
the video?
