Hi I used to work with you back in the SIRS saga days. If you go to the CAA retired staff webb page you will see an advert from me about the souvenier booklet I helped produce. Also in CONTRAIL last year I floated the suggestion for a book similar to the Heathrow Tower one and that I would be willing to assist in editing. Researching for the booklet I found an archive of NATS material that I am currently making sure is securely stored which again would be very useful in a larger volume. If you would like to contact me via an e-mail response thro PPRUNE I would be happy to send you a copy of the booklet and discuss your ideas. I also now have several e-mail addresses of old lags who would certainly be able to provide info.
