en: What is your own background in the Armed Forces?
AH: I joined the Royal Air Force as a Fighter Controller in 1984, and served for 22 years, principally producing what is called the ‘Recognised Air Picture’. For those who have seen films like Battle of Britain I was something like the officer with the telephones who sits at a raised desk looking down over the map of Britain surrounded by airwomen with long poles pushing plaques about. By my day it was all done using computers!
