Not a Wah. I was bimbling along on a CFT the other day and there were a lot of Cadet instructors about, it was a big Cadet camp. Looked like they were all enjoying it, cadets and adults so good on 'em. Anyway, the Officers and AIs were of various ages but quite a few seemed to be in the 18 - 43 bracket. As I went past several younger ones who were marking a route out for the cadets, I got to thinking "Why would you be an AI rather than join the TA?" I was an Air Cadet many years a go but joined TA on the day I was old enough. I can understand some people might have health reasons and so on. What is the motivation to do one rather than the other? As I say this is just out of general curiosity, not a wah so hopefully it can be kept sensible.
