As a cadet (CCF and for a short time ATC), officer with a regular commission (twice) and VR(T) commission, and as an ACLO I have seen few "Walts". I have seen a lot of men and women committed to the Air Cadet cause, who give many hours and days to help produce excellent young citizens. Walts get bored and go and collect engine numbers or something else.
You're having a laugh, mate! Its riddled with them - from really minor Walts to the big ones that make the press. Here is an Air Cadet example:
BBC NEWS | UK | England | Cambridgeshire | MBE conman ordered to repay cash
BBC NEWS | UK | England | Cambridgeshire | Ex-police worker and ATC Officer applied for MBE
Wasn't that bored was he? Stuck around long enough to make an elaborate tale to get an MBE!
Just so the Army don't feel left out, here is an ACF Walt:
Walter mitty CSM in the cadets | Army Rumour Service
As for the minor Walts. Just try googling 'walter mitty cadet' in a search engine and you can read some of the stories of fake service records and para wings galore.
I'm not saying that every Air Cadet staff is a Walt, far from it. But they most definately have a full spectrum of Walters amongst their creed.
Rant over and out
