To play devils advocate, if the MoD really wanted to play 'hardball' it could just change the wording for all those being forced out from the flying training system as "failed to meet required standard" [the goalposts move all the time, cutbacks or not]. That way, like the hundreds before you that were "chopped" (despite committing to the Air Force (your words)), the MoD have not had to pay a penny in compensation/redundancy (
AFAIK) or even provide any sort of resettlement training.
Be very careful before taking legal action - as I think has been said on other threads the 'no win no fee' chaps will stay well clear so you could end up losing what little redundancy payments are on offer (plus probably a bit more) paying a lawyer to fight your battle. There are a lot of lawyers on this site - but you'll notice none of them are offering advice for free
Good luck in whatever path you follow.
