1970 - RAF Valley.
Usual start to the day - Met Brief.
We (most of us) freshly released from Fort Cranwell sitting attentively with our regulation short (very!!) back and sides.
Met Man - youngish (older than all of us studes, but relatively young) briefs us. He is dressed very casually - no jacket and tie - with long hair tied back in a ponytail. Quite "hip" probably, if hip was a word in use then. He gives us the full brief, and finishes with "That is what I am required to brief you - what is really going to happen is......................"
He was more often correct than the official version. The benefit of local knowledge, I suspect, and the courage to disagree publicly with his directive from on high.
