I mentioned in... earlier in this record of happenings, that shortly after the telescope began construction, I received that message from the Astromomer Royal Sir Spencer Jones, asking me to join the Air Navigational Committee and I have already related in this record that I did so and subsequently served as a chairman of that committee and then on the Air Warfare Committee, and then on the Aeronautical Research Council. This was a return to an activity, which I had thought I had left behind, but which I nevertheless found extreme interest... of extreme interest.

I was asked to go with a colleague from the Air Warfare Committee to visit the establishment, which I had left TRE in Malvern to see what they were... they were doing and to my amazement they had made absolutely no progress. They had... he... they had succeeded in modifying my last mark of H2S and making it suitable for the V-bombers, which were then in action. But the Fishpond for the rear gunner, which I mentioned, was still in action, and indeed, that system was continued to be used right onto the Falklands war. And, in fact, the modified system which I had left behind me in 1945 was used to bomb the runways and Falkland during that war so many years later, and then, of course, the new devices took over – of guided weapons and... and lasers.
