Money saving...
Do Air Ranks really need to retire on full pay? We still have almost the same number as the end of WWII taking a healthy wedge from us each month whilst everything else has trimmed back to about 5% of what it was.
We could spend the money saved on extra RAFP to ensure that the disabled parking slots outside the squadron are not violated by people not entitled to park there (everyone on the squadron.)
Alternatively, we could get rid of them too....
