:::re  - "There are several books, journal articles, chapters of bioethics textbooks, etc. that have been written specifically on the topic of this article" - Wrong.  There are a number of books that have been written about the Tuskegee syphilis experiment, yes.  There are a numbers of RSs whose focus is Project SHAD, yes.  There are few (if any) RSs that try to cover all human experimentation (ethical or otherwise), solely in the United States.   
 :::This article takes those sources which deal with individual subjects (i.e. the Tuskegee syphilis experiment, and Project SHAD) and combines "material from multiple sources to reach or imply" that the subject as a whole is notable.
