The Brains Behind Thunderbirds is an overview of the show's premise. From a secret laboratory somewhere on Tracy Island, stuttering science genius Brains is your host. During the hour-long documentary, you are introduced to International Rescue's gadget-tastic vehicles: the 15,000 mph Thunderbird 1 rocket piloted by Scott Tracy; the freight-carrying Thunderbird 2 with six different rescue machine pods piloted by brother Virgil; the space rocket Thunderbird 3 with Alan Tracy at the helm; sub-aquatic Thunderbird 4 with Gordon Tracy aboard; and the orbiting space station Thunderbird 5 overseen by a solitary John Tracy. Brains introduces us properly to each of the brothers, their father Jeff, gorgeous London agent Lady Penelope and her butler Parker, and warns us about their deadly enemy The Hood. Although there's little not already known to die-hard fans, it's a no-strings-attached crash-course introduction for everyone else. https://www.youtube.com/watch?v=mKbJtjHPcqE
