Thanks again PN.
Bit late to the party and just picking up on the thread (just getting over a hip operation).
First job out of training was Aircraft Prep at Lyneham!
Ear defenders (when you could find any), basic model with the pads that go over the ears and filled with glycerine, there is nothing much worse than having one split and go dribbling down your neck when on a ground run when its raining anyway!
That set the scene for the rest of my time, a couple of years Hunter Avpin starts and then Lightnings and then Tankers.
Result, a "wonderful" high pitched tinnitus plus deaf in one ear and partly gone in the other.
Told my brilliant local GP and he has arranged for me to go into SpecSavers Cambridge. BTW he did say that he considered the latest NHS models are as good as most others out there, discuss?
