I wasn't an ATCO, but I took the EG at age 52 so that I could get a life.
I can only echo what alfaman and HD have said - but you have to bear in mind that you're going to be on that pension for a hopefully long time, so start wearing out that copy of Excel right now and don't make any decision until you've looked at EVERY possible contingency.
Do I miss the job? Ho Yus, I got to work with some very talented people, and also HD (just joking B!!). The job, sure I miss it, but do I miss the 'politics' and mis-management (which ranged from the incompetent to the downright unacceptable)? Not a jot.......
