essay written by Elon Musk’s first wife during their messy divorce proceedings has drawn renewed attention this week after a flight attendant accused the billionaire of exposing himself during a trip on a private jet. Justine Musk, mother of the SpaceX executive’s five sons, wrote the essay in 2010 for Marie Claire magazine, describing how the couple’s love story eventually turned into a relationship in which she did not recognise herself. She described “warning signs,” even on the night they were married.
