Chug I am sure that I benefitted greatly from being shouted at by D.I.'s -both times I went through the system. There were certainly no "weeping willows" at the Old Cranwell - at least not for long.
There were always cock ups in postings and personnel records from time to time in my experience -its just that the attitude became more insular and dismissive as the years went by.
I felt the old values of sensitivity to the interests of others slide generally throughout the 70's and 80's as the Air Force seemingly increasingly moved from Dan Dare to Arthur Daley models in its ethos and personal standards.
Or was it that we were all growing up?
