When Dave heard of the passing of one of his personal heroes, Glynn Lunney, he got on the phone to retired NASA Flight Director Gerry Griffin and they put together this special tribute episode for our Apollo@50 series. Glynn Lunney was the fourth NASA Flight Director and was integral to the space program's pioneering Mercury, Gemini and Apollo Projects. He passed away due to a bout with cancer on May 19, 2021.
