Here’s the start of the chapter “Learning to Fly” from a book in our collection: “Don’t be too ambitious at the start. Go slow, and avoid unnecessary risks. At its best there is an element of danger in aviation which cannot be entirely eliminated, but it may be greatly reduced and minimized by the use of common sense.” What good advice! And applicable to other areas of life as well.
The source: Flying Machines: Construction and Operation ; a Practical Book Which Shows, in Illustrations, Working Plans and Text, How to Build and Navigate the Modern Airship by W.J. Jackson and Thos. H. Russell, with an introductory chapter by Octave Chanute. Chicago: Charles C. Thompson, 1910.
If the date doesn’t make it obvious, the “modern airships” under discussion all pretty much look like Wright brothers airplanes. There’s a wonderful spirit of ‘you, too, can build and fly your own air machine’ in this text.
