Slide Rule

Slide Rule: Autobiography of an Engineer is the partial autobiography of the British novelist Nevil Shute. "Most of my adult life, perhaps all the worthwhile part of it, has been spent messing about with airplanes. For 30 years there was a period when airplanes would fly when you wanted them to, but there were still fresh things to be learned on every flight, a period when airplanes were small and so easily built that experiments were cheap and new designs could fly within six months of the first glimmer in the mind of the designer."
"That halcyon period started about 1910 and it was in full flower after WW I when I was a young man; it died with WW II when airplanes had grown too costly and too complicated for individuals to build or even to operate. I count myself lucky that that fleeting period coincided with my youth and my young manhood, and that I had a part in it."
