Extract

I felt indeed very honoured when I was invited to deliver the 30th Lanchester Memorial Lecture. I immediately started reading Frederick W. Lanchester's famous and impressive work ‘Aerodynamics’ published in 1907. It was very interesting to read but of course there was nothing to be found about delta wings at supersonic speeds, which I had offered to talk about, partly because I had studied this for the last 5–10 years and partly because Sweden had been developing delta winged military aircraft since 1948 or so. I also know of course that Great Britain had made impressive progress at the same time particularly Dietrich Küchemann and the group around him. I could therefore expect and fear to have a competent and critical audience to face.
