I caught this one used off Amazon. It's the written record of a symposium held by the Royal Air Force Historical Society in 1997, and published in 1998, and it is fascinating reading. I would most definitely recommend it if you can find a copy.
I've now finished reading my copy and I can very definitely recommend it highly. There is a lot of illumination there that you don't necessarily get elsewhere. IMHO, it's a very necessary addition to any collection of books on the TSR.2.
