Is it theoretically possible? If not, what is closest we could get?

[syhprum]

I believe that that the best that can be achieved is about 3% of the drag that a flat disk of the same diameter would have, this is at subsonic speeds of course

[DoctorBeaver (OP)]

Would I be correct in thinking that at supersonic speeds the least amount of drag possible would be greater than at subsonic speeds?
