Together with Schirra and Don Eisele, Cunningham helped created the first-ever live television transmission from space. It was broadcast from Apollo 7 <em>(October 1968)</em>, which was an<u> eleven-day flight</u> towards moon.
The case Plessey v. Ferguson decided that it was legal for public schools in the United States could be segregated by race. It was late overturned by Brown v. Board of ED.
