It is surprising that in an age when the radio was not entirely reliable (or secure) and when telegraph lines could easily be cut by shelling etc. that more attention was not given to the D.R. message service where the buck eventually stopped Perhaps such blindness to the importance of communications and an over reliance on 'new' technology contributed to our rather poor performance prior to Dunkirk...and possibly after.
Of course it is possible that a staggering 50% shortfall in operating efficiency was compensated for by having 50% more DRs than were actually required!....Ian
