Has TCT ever suggested that she was or had ever been in the RAF, or been trained/qualified by the RAF? I'm not aware of any such claim - quite the reverse since she has many published "CVs" which include no such claims. So there is clearly no Intent to deceive, and as such no offence.
Perhaps wearing RAF wings on her flying suit is not a good idea as it gives the impression she is entitled to wear them. But hey, what's a bit of deception between friends.
