There are masses of information on the net about the history of the Panavia Tornado. A really interesting publication can be found in the RAF Historic Society; I believe called BIRTH OF TORNADO.
I was involved in the RB199 engine development and in-service phases. It was an incredibly advanced engine that pushed to the limits what was possible given the technologies and materials available during the late 60's and early 70's. When certified it had the largest cleared flight envelope and was the only engine capable of operating at Ma 1.2 at sea level (800kts). It's electronic control system was by a long way the most advanced at that time initially being analogue and thus highly complex.
Best of luck with the booklet.
