I think some janky editor messed with it last year and nobody has noticed or checked the sources.
And concerns/mockery of “the flying housewife” alone in close quarters with a handsome navigator, gave way to an affair while en route, a love-child, and divorce? And there is a post on the Talk page from someone claiming to be that child... bonkers!
