Boeing Early History
This is an excellent early history of the Boeing Aircraft Company. I first read it in the late 60's, having received a copy from my first flight instructor. As a pilot and an engineering company founder, I find it accurate and well written. It has much to offer from the aeronautical, business, and engineering perspectives. After finding it on alibris, I bought several copies, and gave them away to my pilot friends. The later editions contain more of Boeing's history although nothing approaching contemporary developments.
