Just to clear up any confusion, it was my post that started the discussion about breath testing (although it did say that I disagree with it, what I really wanted was informed discussion to shut the R5 phone in bods up !) and since reading Danny's post I have chosen to delete it.
Danny clearly does not want the thread to go that way and I would ask that we leave it there, as a courtesy to Capt PpRuNe.
