EASA 'state' flying (including police flying) is not 'public transport' It's the UK CAA that are preventing 60-65 UK single pilot police flying, within UK national boundaries.
My company termination letter at age 60 stated I was being 'dismissed for substantive other reasons' which HR said was the correct terminology.
Before I was 60 I approached Ian Evans, the last great flag bearer for 60+ SP PT flying. He told me if I 'valued my sanity' not to take on the CAA but to go off and enjoy my life!
So I did and I am!
Still flying 902's, though!
