Pontius Navigator.
Why should those of us who left the RAF some time ago be excluded from discussion of current subjects because we do not know the meaning of those initials ? . Yes indeed some of the subjects are only of interest to the current servers but like the ops room door positioning, for some problems, we have seen it all before and can still offer relevant thoughts if we only could understand. Anyway we like to show our interest in our successors and give them support at this trying time.
