Ok, not been in the office much today but I find this rumour pretty hard to believe. If the Service did remove people from flying duties on what grounds do they think they can keep people in?
The Service can retain people formally months and month beyond their PVR date if the Service has an operational need to retain the skills. If they did carry out this daft policy then they would undermine the published reason for not letting you go.
I know the RAF can be a little stupid at times, but this would be breaking new ground. Even the most career-minded senior numpty knows that it will only take one example being leaked to the press before joe-taxpayer will ask why we are paying a chap for a year yet stopping him from doing his job.
Although I have been wrong in the past....
