Air: Part 3

Plot:

With the ship out of hyper-space for twelve hours, Lt. Scott, Sgt. Spencer, Ian, Dr. Rush and others travel down to the planet to find the minerals necessary for the scrubbers to provide them with breathable air. They find a desert planet that should have what they need but they will have to locate a dried lake bed as it will be the likely source. Scott recalls some of his troubled past. As time winds down, some of the team decide to use the gate to transport themselves to a habitable planet, despite Ian's advice to the contrary. Chloe Armstrong communicates with her mother to tell her about what's happened to her father.
