RAF Yearbook
Slightly off thread, but I see that the Royal Air Force Yearbook has been discontinued this year. It's a shame because after my grandad gave me a 1976 copy, I have purchased it every year since.
It became more commercial in recent years, with apparent more adverts than articles, but nevertheless I always looked forward to reading it about this time of year.
Have still got a stack of the copies in my bookcase. Off course in OCD chronological order!
