I leave the RAF and start teaching. The school was tiny and nowhere near anywhere I'd been based.
The chap allocated to be my teacher 'buddy' had a son who used to be in the RAF too (though that wasn't known to the guy who allocated him).
Turns out his son used to be one of my flying instructors on Hawks.
I take my first class. One of the girls has a surname I recognise. Turns out her dad used to fly one of the same aircraft types as me.
Turns out her dad used to be the flying instructor of the son who used to be my flying instructor.
Three weeks later, since she was a member of the RAF section of the cadet force and I'd been asked to run it, I took her flying.
Circle complete!
Oh, and one of the other teachers turned out to have played in the same football team as me, aged 10.
