Dead or alive, the aircrew I referred to come straight in to a place previously preserved for those of a certain amount of earned status and respect.
Previously would be pre-1940 or so then, as aircrew have been promoted Sgt on completion of training since early in WW2. You refer to a situation prior to that, which presumably you never actually 'enjoyed' - unless you're about 90 years old? Any other old ideas you'd like to reinstate while you are at it? Flogging the oiks for 'murmuring' perhaps? 20 lashes for sitting on 'your' bar stool at the mess bar?
Aircrew hold the rank, they are as entitled as any other SNCO to mess membership, get a life.
By the way - calling siggies Nimrod coffee boys is pathetic, frankly, and shows how little you know about what they do.
