JFK, wife Jackie had sex on Air force One a day before his assassination

Former US President and Jackie Kennedy had sex on Air Force One during their short flight from San Antonio to Houston just a day before he was assassinated, it has been revealed.

The revelation was made by late historian and author William Manchester to Philip Nobile, a former staff writer for Esquire and New York magazine, in the mid-70s, the New York Post reported.

At the time, Manchester had admitted to Nobile that he had masked the intimate details in his 1967 book, 'The Death of a President', out of discretion.

Manchester had also added that it was Jackie herself who had told him about the mile-high encounter during one of their interviews in 1964.
