Michigan Mike found this one of Dad's old books: Introduction to Space Dynamics by W.Tyrrell Thomson.


The logo is for North American Aviation. Dad got out of the aerospace business when I was in high school. Only large organizations had computers, calculators were still largely mechanical, and the PC was still years in the future.
