Progress in the post-WWII Fifties, the introduction of the jet engine in the Sixties, and the early technology in the Seventies effectively and efficiently supported safety and the service delivery needs of a slow-growing and largely static system. This book builds upon the need to preserve international civil aviation's corporate memory about facts and people, in the face of ever-constant and often radical change, and the de-personalization of aviation. This is achieved by providing a roadmap of key institutional and operational events that, since the mid-Eighties, have shaped aviation safety thinking into the present-day paradigm, by redeeming failures and revisiting successes, by associating each "fork in the road" to a specific shift in prevailing paradigm and, most importantly, by crediting individuals and teams without whose unique contribution the shifts in paradigms would not have been achieved.
