This thread seems to be turning into discusssion about C over D v E over D. Let us go back to the specific airports. Obviously the ones in question have met the requirement for D Towers. I see absoolutely no need for anything other than G over the top of them. The E discusssion especially from Mr Smith's position is purely from a fundamental stand point of wanting E all the way down to any approach anywhere. Now THAT is something this country neither needs or wants.
