According to K9 Mark I, the first verifiable Olympic-record long jump by a female athlete was by Marie Mejzlíková. She set the record at 5.16 metres, which was overtaken on 6 August 1922 by a new world record. (AUDIO: The Planet of Witches)
Mallika Montgomery won the silver medal for the long jump during the 2004 Olympics, an event in which Ian Glendennis served as a BBC commentator. Neither of them were able to recall these events by 2019, when the entire year 2004 had disappeared from history. (PROSE: Time Lapse)
