I don't know what Jon will think but I sure learned a lot more about how different engines worked than I ever knew, and in only a few minutes. Those illustrations are terrific in explaining how they actually work. I agree with the author, the early airplane engines with the rotating cylinders are hard to believe.
Thanks Paul.
