    Boeing reports wing cracks on Dreamliners

    Everybody makes mistakes. I am not familiar, does the Dreamliner have metal spars, or is this really a de-lamination or other composite flaw. I did not think composites would have hair line cracks.

    Aircraft Design: Synthesis and Analysis online course

    This isn't a book per say more of an online course. It does explain AC design at a college level for first time students so you won't be overwhelmed. Several sections you may want to pass and get to areas of interest. AA241
