When I retired in late '08, I was fully intending to stay on providing LARS, but regretfully it was not to be (unfavourable Ts & Cs) so I became a FISO at a local airfield instead. Even now, pilots come in and say 'weren't you at Farnborough?' or 'I thought I had the wrong frequency selected when I heard your voice'. In some ways it's more challenging than controlling as you often have to handle the RTF plus file flight plans and take landing fees all at the same time, but having said that, I'd still rather be doing radar.
