I can't imagine any one who is sane even remotely thinking of going back, but I suppose that not every one can re-adjust to the real world. I know many many Air Engs who have left but absolutely none who have re-enlisted. Of all those who left and went flying on civvy licences, non are flying now.
I do know of one who PMA got in touch with and asked him to reconsider his decision to leave and that was within the last six months. He had been out about 18 months or so.
I am sure the powers that be will find some way of sorting the problem out!
