The main issue here is being ignored, namely: if the RAF is scrapped, the RN and Army would have to find another force to try and transfer to. All the AAC chaps would try and transfer to the RN, who would be busy applying to the RAAF or any other country sensible enough to speak English and have an Air Force. The resultant chaos would decimate the Services and plunge the country into anarchy. In effect, the presence of the RAF is preserving national security saving the country from certain doom. Again.
Banter warning red: I am not being serious. I say again, I am not being serious. That is all.
