Squadron patches
I collect aircrew patches for various aircraft types (most of which are air defence) for a hobby, and also to support the Squadron(s) whenever they sell them at air shows I attend.
I have always wondered where it all started, and how it started and I haven't been able to find anything definitive yet - could any PPRuNe member(s) shed some light on it?
It seems obvious to me that the patches form part of the identity of the Unit and wearing them gives aircrew a sense of belonging and camaraderie, but the history of wearing patches has eluded me!
