Well its definitely happening.
Within the last few weeks I bumped into an old friend (in the pub, of course) who is just leaving the Paras after 6 years service.
When asked what he was going to do in civvy street, he said he was thinking of the police but told me of the marshal job.
He let on he was somewhere in the recruitment process. I was quite taken aback because I hadn't realised it was going on in the UK; I had thought he was talking about working in the States. He confirmed it was for UK-based work. When asked who the contracting airlines are he suddenly grew all hush-hush, and wouldn't say another thing about it.
He was pretty hammered, and is not the brightest light in the harbour (even on a good day) so all in all I got the message he had said a bit much to have piqued such interest.
Make of that what you will.
