Having read the report that YS posted there are still lots of things that will probably never enter the public domain.
Most of the speakers at the RAF historical group are senior. I just wondered, whilst I have a little grey matter left if I should write down some of the things I was involved in as a very junior member of the team. I never had the complete picture, rightly so. As the years have progressed I try to put into context some of the stuff I did back then. I wish I had kept a diary. I know most of the design drawings and files from the time were destroyed.
