It was impossible to look at those young men, who might within a matter of minutes be fighting and dying to save us, without mingled emotions of wonder, gratitude, and humility. The physical and mental strain of the long hours at dispersal, the constant flying at high altitudes (two or three sorties a day were normal, six or seven not uncommon), must have been prodigious.
And yet they were so cheerful, so confident, and so obviously dedicated. They were always thrilled to see Churchill, and they gave me a kindly welcome.
They are certainly formidable obstructions to most of us especially in the hours of darkness when one is confronted by barriers in the most unexpected places. I am told that Winston is mainly responsible for them and takes the deepest interest in them. He appears to spend a lot of time inspecting our defences all over the country.
