If Pilot is all you want then tell them...they've accepted you once they'll take you again.
Im my opinion this is highly unlikely. Pilot training has to be commenced before your 25th birthday. This means AFTER the completion of IOT. Sorry JRM but you have got everything stacked against you. Age, timing (we just dont need that many so can afford to be very selective), and commitment. You let us down once, and yourself for that matter, so any pilot slot will rightly go to someone who seems more determined to grab the chance that many aspire to but few are given.
As to the suggestion of Fighter Controller and the E3D, I think this is also a false dawn. They are a busted flush and they will almost all be replaced with WSOs in the coming years. What else we going to do with all those F3 Navs!
Good luck at OASC and say hello to me when i come to stores for a new blanket next year.
