Part of the issue here is that there is an effort under way to improve the security culture throughout the RAF, tied in with the arrival of F35, RJ and other highly classified capabilities. Witness the profusion of ID lanyards, controls on social media use, etc. The reason to be like that at a training base is precisely that it’s a cultural shift being sought, so the trainees need to be indoctrinated and the staff need not to get ‘lazy’ while away from the front line. I’m not saying that this is anything more than a sticking plaster to make up for the unwillingness to invest in US-style physical security measures, by the way - just explaining why things might seem to have changed.
