Season 2 Episode 3 – Deep Search
Alan makes first contact with an alien life form! This occurs when Thunderbird 3 is called out to Jupiter’s moon Europa to save a pair of documentarians.
Adventure documentarians Ellie and Buddy Pendergasts fall into the ice ocean on Jupiter’s moon Europa, but manage to send out an emergency beacon.
Alan and Gordon take a long flight on Thunderbird 3 to their location. They find the Pendergasts, who survived inside a small mobile rover.
Before they head out, Alan leads them to their first encounter of alien life.
Their exit stalls when the ocean surface seals up, but they find a way to punch through the ice and fly away.
