Regarding the EFT element, I'm just going from what guys have said getting onto ground school at the moment. I also know a guy who graduated 2 years ago who still hasn't head anything regarding his training... not trying to make anything up.
I've also been told "anything is possible", granted its nothing firm and I'm well aware this type of move isn't common. But an example was given of a guy who crossed to FJ after being on ME. The discussion was all in context of RPAS crossovers and was given by an AVM, so I'd say fairly well substantiated. Again, just going off what I've been told. If the RAF are happy to spread false information to candidates like this then so be it but don't shoot the messenger. And I wouldn't put it down to a "recruitment sales pitch" as I personally made it clear I was past that.
