I'm reading it from chapters 12 to 27 and I found a it fascinating book. Highly recommended for serious aerospace amateur. You can know from the designer itself how an aircraft born from idea to hardware with real examples from Mr Raymer work at Rockwell. The manufacturer receives an order and there is a process to offer the best solution to fulfill the customer's needs, often in competence with other manufacturers. I've learnt that powerful simulation software is used even to simulate war scenarios to choose the optimal design. Working on warplanes sometimes you also depend on parallel developments from other companies (weapons, sensors...) to make your design succesful. I love the book.
I found very interesting when Dan Raymer describes some examples of designer expectations for their designs that later proved to be wrong. That made me think about the Luft 46 hysteria. As much as I learn about aerospace I find Luft 46 mania still more funny.
Thanks a lot Mr Raymer for that great book.
