The hon. Lady makes a powerful point. The RAF is more than just the service itself. It is all those people who contribute to it so much. It is the businesses that help to create these amazing flying machines, which have been so instrumental in defending Britain repeatedly in the past and will be so again. I pay tribute to those who bring that to life. I take this opportunity to mention the Boulton Paul Aircraft Company, which was in my constituency and produced the Defiant aircraft during the second world war, and the many people of the Boulton Paul Aircraft Society who have kept alive not only the skills of aircraft production but the contribution by so many people across the west midlands and the country to the Royal Air Force.
