The same weekend as the moon landing, the Ted Kennedy's tragic car accident at Chappaquiddick island in Massachusetts occurred. Senator Ted Kennedy's negligence led to the death of passenger Mary Jo Kopechne who was trapped inside the car after the crash. 
As speechwriter William Safire later put it referring to the juxtaposition of the moon landing and car crash on the same weekend: “the dark counterpoint at Chappaquiddick, which ended the dynastic potential of the brother of the President who launched the Apollo journey.”
