The company diary of Swissair is an indisputable document and the foundation for any future engagement with the history of the Swiss national carrier from its founding to its grounding. It includes all important corporate decisions, many previously little-known background details, all incidents in flight operations, all routes, all countries, and all aircraft types – in short, everything that defines the history of the legendary airline. For the first time, it is documented and made accessible in full breadth and on a day-to-day basis. The new standard work on the history of air traffic in Switzerland impresses with its concept: it meticulously records, in easily understandable English, what was important for Swissair over its more than 70 years of existence. From 1931 to 2002, all incidents are comprehensively documented. The book neither judges nor condemns.
