An essential volume in the NASA History Series by Robert C. Seamans, Jr., the Associate Administrator of NASA during the Apollo program. A stirring insider’s account of NASA and the manned space program at the highest levels. Relationships with the Department of Defense, the Apollo 204 fire, the assassination of President Kennedy, and more.Aiming at Targets is a series of fascinating topical vignettes covering the author’s professional life. Taken together, like broad brushstrokes in an impressionist painting, they give a better picture of Bob Seamans and his work than a detailed recitation of facts and dates could hope to do. This is a cheerful account of an interesting and successful career. The book is full of good stories, with many memorable characters. Like the proverbial sundial, it counts the sunny hours.
