This book describes a very ds "Operational" style the conduct of the French and European space adventure. What makes this book different from other books on the subject of space is that, firstly, we have here a multitude of details related to the life of the teams who lived these successions missions and Second, the precise description of the context of each mission ... and not a posteriori analysis! This gives, I think, a good idea of the decision context and therefore boldness, vision and tenacity that a "Project Manager" must have. Only having lived an operational events could write such a book! Congratulations Mr Le Fevre !!
