John Tracy is a fictional character from Gerry Anderson's Supermarionation television series Thunderbirds and the subsequent films Thunderbirds Are Go Thunderbird 6 and the live-action film Thunderbirds.
John Tracy was initially to be one of the main characters in the series, but he became the least favourite character of creator Gerry Anderson and consequently had a much more limited role in the series than originally intended. John was the first of the Tracy brothers to be cast. Actor Ray Barrett was so impressed with the attractive nature of the face of the marionette, who was modeled on head-shots of rock singer Adam Faith and actor Charlton Heston that he immediately advised co-producer Sylvia Anderson that he wanted to play the studious young astronaut with the boyish quiff.
The second son of Jeff Tracy (founder and financier of International Rescue), John was named after astronaut John Glenn. Sources vary in the canon of the Thunderbirds series as to John's age and birth date, although one written source suggests that he was born on 28 October 2041 - this would make him the third son. The majority of sources and two decades of Thunderbirds calendars cite John's birthday as 8 October and he is 25 years of age. Chris Bentley, author of 'The Complete Book Of Thunderbirds' erroneously cited Gerry Anderson as the source of the misinformation about the birth order of the Tracy brothers but later admitted that he was using the order of the brothers as shown in the credits. Most source books on Thunderbirds prior to the 'Complete' book noted that the birth order matches the number of the Thunderbirds ships, save that the third brother (John) and fifth brother (Alan) trade shifts aboard their respective crafts. Also, the novel 'Operation: Asteroids' from 1965 clearly states that Scott and Virgil are "Jeff's eldest sons."
John is a noted scholar of astronomy and has authored several popular astronomy textbooks. He is a graduate of Harvard University with a degree in Advanced Telecommunications.  John's quiet intellectual nature and interest in astronomy make him the natural choice for the solitary life as the occupant of space station Thunderbird 5, monitoring for distress calls from around the world. He has only ever been seen physically involved in a rescue during the episode "Danger At Ocean Deep," although he says at the end of that episode that he has already been on a "dozen" rescues. According to Carlton Books 'Lady Penelope's Secrets,' John is known to be exceedingly patient, kindly and gracious and possessed of both great intelligence and poise as gifts inherited from his talented mother.
In the 2015 series, John is still the 'pilot' of Thunderbird Five, but his role is greatly expanded beyond simply receiving calls for help, often providing aid in coordinating the rescue missions via long-distance communication. He is voiced by Thomas Brodie-Sangster.
John is shown as being an emotional introvert, who prefers spending his spare time eating bagels, watching TV (his favourite show is Stingray) and stargazing. He is generally a loner, who doesn't like having to spend more time on Earth than he has to, as he's now the lone operator of TB5 until EOS comes, a program that he designed by himself.
