Playback: The Glass Stratosphere

As billionaires Jeff Bezos and Richard Branson lead the charge for a new commercial space race, we revisit an episode from our archives: What if women had been among the first to head to the moon? A NASA physician thought that wasn't such a far-fetched idea back in the 1960s. He developed the physical and psychological tests used to select NASA's first male astronauts. We'll investigate what happened to his program and what the women who were involved had to say. For more information about this episode, visit natgeo.com/overheard Want more?
