A series of mistakes caused an oxygen tank to explode a couple days into the flight and the crew and mission control had to work the almost impossible task of returning to Earth. The girls walk through the mission-saving procedures created, the logistics of saving power and water, and talk about the famous movie based off of this event where they decide this film began their loves of Tom Hanks.
