Back in the "bad old days" when Officers commanded (with the Warrant Officer's say so and the support of the SNCO's), we used to have eight RAF Stations "At Home" days on the nearest weekend to 15th September
Eight? I distinctly remember when just about every RAF and RAuxAF Station held 'Battle of Britain' open days. Even the Bomber Command ones.
Our local station was RAF Thornaby, home to RAuxAF 608 Squadron and their DeHavilland Vampires and it was where I got Avtur in my blood at the age of five.
