In Our Youth explores the lives of thirty-two young Canadian military and civilian flyers, viewed through the medium of archival photography. All of these young men were pilots in the First World War, a time when flying was pure adventure and danger. Some of them were from humble origins, some from elite families, some became heroes, one was cowardly, and most have now faded from our attention. However, all embraced the romance of flight and the danger of war.

Although much of the book is focused on military experiences—including the mental stress and injuries faced by pilots who had barely reached adulthood—the book looks beyond war, examining the fascinating world of civilian aviation from 1908 to 1941. Featuring long-hidden photography uncovered from provincial archives, confidential military records, and precious family collections, this book covers the lives of many young Canadians who made important contributions as they flew and fought in what seem today to be the flimsiest of machines.
