Thunderbirds machines

Last updated

The Thunderbird machines are a series of vehicles imagined for the mid-1960s film and television Thunderbirds series developed by Gerry Anderson. The released work began with the Supermarionation television series Thunderbirds and was followed by subsequent feature films Thunderbirds Are Go and Thunderbird 6 in 1965–68. The series featured a large variety of futuristic air, land and sea vehicles and machines, the majority of which were designed by special effects director Derek Meddings.


In the context of the series, most of the advanced machines appearing in the series belonged to the International Rescue organisation and were used during their rescues. These were known as the "Thunderbirds", of which there were five core machines and a variety of other rescue craft. It was after these that the series was named. In the series, all of the International Rescue vehicles were designed by the organisation's resident technical genius known as Brains. [1]

The use of these models in Anderson's Supermarionation productions beginning with Supercar was a significant advance in television production. This dirt and wear was applied as a way of adding realism and countering the miniature models' toy-like appearance.[ citation needed ]

Thunderbird fleet

International Rescue's fleet consists of five principal craft; the Thunderbirds:

Thunderbird 1

Maximum speed15,000 miles per hour (24,000 km/h) [2] [3]
PowerRocket propellant, turbo-jet fuel, atomic fusion reactor
Mass140 tons [2]
Length115 feet (35 m) [2] [3]
WidthFuselage: 12 feet (3.7 m)
Wingspan: 80 feet (24 m) [2] [3]
Pilot: Scott Tracy

A sleek, variable geometry ( swing wing ) hypersonic rocket plane, blue and grey in colour, used for fast response, rescue zone reconnaissance, and as a mobile control base. Thunderbird 1 is endowed with VTOL capabilities which are demonstrated in many episodes, and its take-off from Tracy Island is most often vertical. [4]

The length of Thunderbird 1 is a matter of debate,[ citation needed ] with various sources giving values of 80, 100 and 115 feet (24, 30 and 35 m). However, the last figure is now generally accepted,[ citation needed ] placing the aircraft wingspan at 80 feet (24 m).

With a maximum speed of 15,000 miles per hour (24,000 km/h) (Mach 19.7), it can reach anywhere on Earth within an hour's flight if a great circle route can be flown. Thunderbird 1 is hangared beneath the main house on Tracy Island and launches vertically from a pad camouflaged by a swimming pool which slides aside.

The aircraft is primarily piloted by Scott Tracy, with Alan taking his place when he is unavailable as Thunderbirds 1 and 3 are rarely required on the same mission (such as in the episode "Atlantic Inferno", where Scott, as the eldest Tracy brother, takes charge while Jeff is on holiday). Jeff described it as "sleek, first and fast" at the beginning of Thunderbird 6 .

One of the most popular errors noticed amongst Thunderbirds fans is the pilot's ability to control almost all of the many functions of the rocket by simply moving one of the two control levers forward or back. [5] This is explained by other Thunderbirds fans as a precursor to the current system of electronic joystick controls that are backed up by sophisticated avionics computers.[ citation needed ]

As the reconnaissance craft, Thunderbird 1 featured in virtually every episode of the series as a means of assessing what vehicles would be required for a rescue. It does not appear in the episodes "Sun Probe", "The Impostors", "Ricochet" and "Give or Take a Million".

In "The Uninvited", Thunderbird 1 was shot down by the Zombite Fighters and crashed into the desert but Scott was soon found by two explorers.

Thunderbird 1 appears in the 2004 live action film Thunderbirds , where it has an updated look similar to the original; coloured silver grey, with blue and yellow detailing and red nose cone.

In the remake series Thunderbirds Are Go, Thunderbird 1 retains the same role it has in the original series. However, like all of the Thunderbirds, it is able to be piloted remotely via Scott's wrist console. Thunderbird 1 also possesses an electromagnetic cable that can be fired from the open cargo bay, allowing it to lift or tow objects. The electromagnet at the end of the cable can be swapped for a clip. It also carries a Skypod, a short-range flying capsule that allows Scott to get in close to a target where Thunderbird 1's size would be a disadvantage, and several remote operated drones that can be deployed to search multiple areas or places that cannot be reached by conventional means.

Thunderbird 2 is International Rescue's heavy-duty transporter aircraft, green in colour, which carries rescue equipment to the danger zone in one of 6 pods (including Thunderbird 4 in Pod 4). Thunderbird 2 is a large, green VTOL aircraft that is used in most earth-based rescue missions. It is piloted by Virgil Tracy, who is often accompanied by either Scott Tracy, Alan Tracy, Gordon Tracy, Brains or sometimes Tin-Tin, and on at least one occasion by Lady Penelope.

Thunderbird 2 is 250 feet (76 m) long with a wingspan of 180 feet (55 m) and a height of 60 feet (18 m). A long-range craft, it is capable of reaching anywhere in the world without refueling, often shown flying just above sea level and has a maximum speed of 6,000 miles per hour (9,700 km/h), which is roughly Mach 7.82 (but cruises at 2,000 miles per hour (3,200 km/h), roughly Mach 2.6). It therefore arrives at the danger zone later than Thunderbird 1. [9]

Designer Derek Meddings maintained that the forward-swept wings were a purely aesthetic decision intended to make Thunderbird 2 stand out next to real-life aircraft: "All aircraft have swept-back wings, so I thought I'd sweep mine forward." [10] A design error on the original TB2 was corrected in later renditions. The telescopic legs which raise the craft were placed on the superstructure which prevented the pods from being loaded from a conveyor belt as seen in the original series' opening credits.

The launch sequence begins with Thunderbird 2 taxiing through a concealed hangar door disguised as a cliff face onto a runway flanked with palm trees that fall back to accommodate the large wingspan. The aircraft is then raised on a platform until it is at the correct angle for take-off. A blast shield rises at the rear of the launch ramp, channeling the exhaust of the rear engines through a series of tunnels to the other side of the island. Thunderbird 2 launches from this angle rather than using the VTOL thrusters because it is much more fuel efficient. [11]

Thunderbird 2 is the most frequently seen of all the Thunderbirds, appearing in all but one episode of the TV series ("The Impostors") and also appearing in all three films.

In "Terror in New York City", Thunderbird 2 was fired upon and crippled by the USN Sentinel and remained out of operation for the rest of the episode. The vehicle was subsequently repaired using parts sourced from several different aircraft companies in order to protect the secrets of the aircraft's design.

In the 2004 live action film, Thunderbird 2 was given an updated design where it doesn't have a hollowed-out middle to carry any Pods, and instead, has a solid body that carries a number of Pod Vehicles within.

Thunderbird 2 features a slightly updated design (with the Pods a rectangular prism and called Modules) in the series Thunderbirds Are Go while still retaining its traditional role of the team's workhorse. The craft now features the same electromagnetic cable reels as Thunderbird 1, though they can only be used if Thunderbird 2 has no Modules attached. Like the other Thunderbirds, Thunderbird 2 can be piloted remotely via Virgil's wrist device.

The contents of Thunderbird 2's Modules differ slightly from the original series. Module 1 specializes in carrying fire-fighting equipment and contains large speakers and subwoofers topside that are used primarily to emit low-frequency sound waves for use against large fires. It also comes with two under slung liquid nitrogen cannons. Module 2 contains three "Pods," special units that can be converted and customized into a number of different rescue vehicles such as the Mole. Module 3 contains electromagnetic "grabs", large claws designed to lift objects heavier than the standard electromagnetic cables can handle. The nose of the craft also contains a set of grabs that can hold a set of seats for lifting people. Module 4 contains Thunderbird 4 just like Pod 4 did in the original series. Module 5 consists of a fuel pump to refuel other vessels as well as seats like Module 3. Module 6, like Module 4 is capable of carrying Thunderbird 4, but it is used in rare occasions of Thunderbird 2 having to travel into space.

A reusable vertically launched SSTO (Single Stage To Orbit) spacecraft used for space rescue and maintenance of Thunderbird 5. Thunderbird 3 is 287 feet (87 m) long, with a 23 feet (7 m) wide body and a 79 feet (24 m) span (including engines). It is red in colour. [15] Another source says it's orange. [16]

Thunderbird 3 is unique among the Thunderbird craft in having its dimensions quoted in an episode of the series: in "Give or Take a Million" Jeff Tracy states that the spacecraft stands 287 feet (87 m) high. However, Brains, the designer of Thunderbird 3, said in a videotaped interview, [17] that Thunderbird 3 was "200 feet [61 m] in height."

Scale model of the reimagined Thunderbird 3 from the 2004 film

Another problem with the stated size is evident in the Thunderbird 3 launch scenes. For the craft to be over 200 feet, the ceiling of the roundhouse it passes through on take-off would need to be in excess of 50 feet (15 m) high and the balcony rail 25 feet (7.6 m) high.[ original research? ]

The spacecraft uses chemical rockets for lift-off and boost, and an ion drive for propulsion while in space. Thunderbird 3 is hangared beneath the "Round House" on Tracy Island, and is primarily piloted by Alan or John Tracy, although Scott often co-pilots. Since John is usually seen in Thunderbird 5, he is rarely seen piloting the spacecraft (only in "The Mighty Atom" and "Danger at Ocean Deep" and "The Uninvited", and never in a rescue situation). In "Ricochet", Virgil is seen piloting Thunderbird 3.

This craft was used for space rescues in "Sun Probe", "Ricochet", "The Impostors" as well as escorting the Zero-X briefly in Thunderbirds Are Go .[ citation needed ]

Thunderbird 3 features a slightly different design in the series Thunderbirds Are Go. The three support structures on the engines are now grapple arms that can swing forward, which hold four electromagnetic cables each, and the nosecone of the craft holds a drill. The cockpit area is able to rotate to keep the pilot oriented "up" in relation to Earth regardless of the orientation of the rest of the craft. Like Thunderbird 2, Thunderbird 3 features a customizable Pod Vehicle in its cargo bay that's specialized for outer space rescues. Like the rest of the Thunderbirds, Thunderbird 3 can be piloted remotely via Alan's wrist device.

Aquanaut: Gordon Tracy

Piloted by aquanaut Gordon Tracy, Thunderbird 4 is 9 metres (30 ft) long and 3.4 metres (11 ft) wide. This makes it the smallest of the Thunderbirds vehicles, but not the smallest of the Pod Vehicles. [21]

A small yellow-coloured utility submersible for underwater rescue, Thunderbird 4 is carried aboard Thunderbird 2, nearly always in Pod 4, although it was once transported in Pod 6 ("Attack of the Alligators"). In the episode "Terror in New York City", the craft is launched by emergency procedure, from the Thunderbird 2 hangar and sliding along the island runway, with the runway's overhang automatically dropping into the sea as Thunderbird 4 approaches it.

Thunderbird 4's slow speed makes it impractical for the craft to travel on its own; when Thunderbird 2 was temporarily out of action and Thunderbird 4 was needed, Jeff Tracy contacted the navy vessel Sentinel - the fastest ship in the fleet and, ironically, unintentionally responsible for incapacitating Thunderbird 2 in the first place - to give Thunderbird 4 a lift to the danger zone.

The submersible is fitted with an adjustable searchlight which can be raised or lowered to reveal a variety of rescue instruments, such as cutting lasers, electromagnets, demolition rockets and battering rams, which can be extended from the nose section.

Thunderbird 4 does not play an active role in the films Thunderbirds Are Go (1966) and Thunderbird 6 (1968). It does, however, appear in the opening title sequence of Thunderbirds Are Go. In Thunderbird 6, Jeff Tracy gives a "run down" on each of the Thunderbirds machines, where Thunderbird 4 makes a brief appearance.

The submersible also appears in the 2004 live action film with an updated design, including space for two operators, larger cockpit windows, searchlights and two underslung claws. However, it is handled by Alan Tracy instead of Gordon, because Gordon is unavailable, having been stranded along with his older brothers and father in space and unable to arrive in time.

Thunderbird 4 features a slightly updated and streamlined design in Thunderbirds Are Go and has a few new features compared to its original counterpart, now possessing a pair of deployable grapple arms and two "dry tube" evacuation pods in its stern. Like the rest of the Thunderbirds, it is able to be piloted remotely via Gordon's wrist device.

During a rescue mission on Jupiter's moon Europa in the episode "Deep Search", it was shown that Thunderbird 4 can also be transported in Thunderbird 3, although it was also provided with various new features to cope with the icy conditions on Europa. When not in use, Thunderbird 4 is housed both in one of Thunderbird 2's Modules and a water tank seen in the main Tracy Island hangar so it can launch from the island when necessary.

Space Monitor: John Tracy or Alan Tracy

The largest rescue vehicle of the Thunderbirds inventory, which is gold, black and grey in colour, Thunderbird 5 is an Earth-orbiting space station which monitors all broadcasts around the globe for calls for help and also manages communications within International Rescue. [24]

Measuring 122 metres (400 ft) long, 90 metres (300 ft) wide, and 83 metres (272 ft) tall, Thunderbird 5 is equipped with almost completely automated onboard systems, allowing the entire station to be run by a single crew member. Thunderbird 5 is primarily commanded by John Tracy, although he is periodically relieved by Alan (according to the storyline, John and Alan swap roles once a month, one piloting Thunderbird 3 and the other monitoring Thunderbird 5, but such was writer Gerry Anderson's dislike for the character of John, that he was usually exiled to the space station). Derek Meddings designed Thunderbird 5 after the other machines and apparently based the design on the Tracy Island Roundhouse model (through which Thunderbird 3 launches). [25]

Thunderbird 5 is located in a geosynchronous orbit, 22,400 miles (36,000 km) above the Pacific Ocean and believed to be above Tracy Island. Thunderbird 5 is electronically cloaked to avoid detection from ground-based radar or other spacecraft's sensor systems.

In the series Thunderbirds Are Go, Thunderbird 5 features the most extensive redesign of the fleet being more akin to modern day space stations. It now features a rotating habitation ring, which uses centrifugal force to provide occupants with artificial gravity. The station has a holographic computer system, also present within the Tracy home as well as the other Thunderbirds, which allows John to have face-to-face conversations with the rest of the team and display information relevant to missions. Thunderbird 5 is also equipped with a space elevator, a rocket-equipped pod on a length of cable, which lets John travel between the station and Tracy Island at will, without having to rely on Thunderbird 3. The station is also equipped with one configurable Pod vehicle. Thunderbird 5's surveillance and data technology are far more advanced compared to its original counterpart, with it able to access almost any kind of digital information that is not secured.

From the episode "EOS" onward, the station is co-operated by the artificial intelligence EOS, which has access to all of the station's systems. The entity, which was created by accident in the previous episode, "Runaway," originally had a violent sense of self-preservation extending into paranoia, which led to it seizing control of the station and attempting to kill John Tracy. However, John is able to convince it that no one is threatening it and it becomes his on-board companion, albeit with a mischievous streak.

Critical response

In a list of "Top Ten Cool Sci-Fi Vehicles", ranks Thunderbird 4 seventh. [26]

Dr Phillip Atcliffe, an aerospace engineer based at the University of Salford, has discussed the real-world viability of the Thunderbird designs. Among his observations are wings of questionable function or value (in the case of Thunderbirds 1 and 2) and a lack of streamlining (Thunderbirds 1, 2 and 4). Atcliffe also queries how Thunderbird 3 would be able to manage its roll and states that International Rescue would probably need other space stations besides Thunderbird 5 to achieve global radio coverage. [27]

According to Theo de Klerk, none of the Thunderbirds seem to have adequate capacity for large amounts of fuel, or turbo generators to convert the heat from their nuclear reactors. De Klerk also states that both Thunderbirds 1 and 2 would be hindered by the drag formed by their engine blocks. He adds that the single VTOL rocket in Thunderbird 1's block would provide little stability during lift-off from Tracy Island, and that given Thunderbird 2's shape, weight and short runway, it is debatable whether that craft could achieve enough lift to take off. [28]

On Thunderbirds 3 and 5, de Klerk states that with only three main rocket engines, Thunderbird 3 could be unstable in flight, while three supporting satellites would need to be positioned around the Earth to compensate for Thunderbird 5's radio blind spots. He also notes that the crew of Thunderbird 3 apparently do not lie on their backs for lift-off, despite the increased G-force of space launches, and that while both Thunderbirds 3 and 5 produce artificial gravity for their occupants, it is unclear how. De Klerk considers Thunderbird 4 to have the least practical design of the fleet, stating that its non-cylindrical shape makes it ill-adapted to extreme underwater pressures. [28]

Other International Rescue vehicles

Thunderbird 2 Pod Vehicles

Thunderbird 2 carries specialized rescue vehicles and equipment to disaster sites in one of six interchangeable Pods. The "Pod Vehicles" are stored within the aircraft's cavernous hangar or kept on standby within the Pods themselves. In the series Thunderbirds Are Go, the Pods Vehicles can be converted and customized into a number of different rescue vehicles for different uses.

Thunderbird 6

In the film Thunderbird 6 (1968), Jeff Tracy tasks Brains with designing a sixth Thunderbird vehicle. Brains sees all of his proposals rejected, but after Alan Tracy's restored de Havilland Tiger Moth plays a vital role in saving the occupants of the stricken airship Skyship One , he successfully pitches the biplane as the new "Thunderbird 6".

Thunderbird Shadow (or Thunderbird S) is the newest addition to International Rescue's fleet of vehicles in the 2015 reboot series Thunderbirds Are Go .

Black in colour, it is a highly agile, VTOL-capable hypersonic stealth aircraft piloted by the organisation's Chief of Security Tanusha "Kayo" Kyrano. It is primarily used for covert operations related to protecting International Rescue as well as support for land and air-based rescues. The cockpit section doubles as a high speed "Shadow Bike" motorcycle which can be dropped to the ground from the craft's fuselage when aerial pursuit becomes impractical while remaining in remote control contact. The ship features a pair of grappling claws in place of traditional landing gear, allowing it to perch on walls, ceilings, and other vehicles. The claws have also been used to carry cargo. Additionally, Thunderbird Shadow is equipped with electromagnetic cables, a sonic cannon, and stealth mode "optical camouflage" cloaking technology, allowing it to appear invisible to the naked eye and radar. It can also launch electronic disabling devices onto vehicles in order to take control of them when in range.

Thunderbird Shadow's launch area on Tracy Island is located on a rock outcrop in a hangar shared with Thunderbirds 1, 3 and 4. Once Kayo is geared up in her flight suit, she ascends to the main body of the ship in the Shadow Bike. The craft is then carried backwards on a turntable and up a wall via a rail. The turntable then rotates 180 degrees so the nose faces up, just as the wall flips round to take the ship outdoors (the exterior is disguised as a rock façade of the island). Thunderbird Shadow takes off from there.

Thunderbird Shadow was designed by Shōji Kawamori, best known as the creator and mechanical designer of the Macross franchise.

This huge yellow tree-felling machine featured in the episode "Path of Destruction". Powered by an atomic reactor, but with a wood processing plant dependent on the chemical fuel 'Superon', the Crablogger was designed by Jim Lucas of Robotics International in England. The machine was equipped with two large arms with a giant central chainsaw which would cut a tree at the base before passing it through an opening at the front. Inside the Crablogger, the tree was reduced to wood pulp which was regularly collected by tankers.

Designed to clear areas of forestation to make way for road developments, much of the Crablogger's systems were automated, although a crew was required to monitor these systems. In the episode "Path of Destruction", the crew were incapacitated by food poisoning, resulting in the machine going out of control. [38] [39]

The Fireflash, a hypersonic airliner, appeared in the episodes "Trapped in the Sky", "Operation Crash-Dive", "The Impostors", "The Man from MI.5" and "The Duchess Assignment", as well as in a flashback sequence in "Security Hazard". It has six atomic motors that enable it to stay in the air for a maximum of six months; however, their radiation shielding must be maintained frequently, or the passengers will be able to spend a maximum of only three hours in the aircraft before succumbing to radiation sickness.

The craft weighs 1,806 tons, has a wingspan of 180 feet, is 380 feet in length, and its maximum speed is Mach 6 (approximately 4,500 mph or 7,200 km/h), and it can fly at heights above 250,000 feet (76,000 m). A novel feature is that the flight deck is built into the tail fin. Like many in real life, this aircraft has two decks, but also features luxury facilities such as a cocktail lounge housed within glazed sections of the wings' leading edges. Fireflash was commissioned by Air Terrainean (a.k.a. Terrainean Airways). [40] [41]


Multi-purpose jet-powered VTOL aircraft, helijets appear in numerous episodes and are widely used by civilian and military organizations. A variety of different designs are seen over the course of the series and were also seen in Anderson's next series Captain Scarlet and the Mysterons . Some versions seem to be based on the fuselage design of the Kaman HH-43 Huskie helicopter of the early 1960s. It is assumed that the production team modelers modified commercial plastic models (probably the 1/32 scale Hawk kit) of the helicopter for use in the series.

Martian Space Probe

Appearing in the episode "Day of Disaster", the Martian Space Probe is an automated mini-rocket designed by Professor Wingrove and built to rival the Zero-X project. Due to the position of Mars, it was shipped over to England to take off. En route to its launch site, the Allington suspension bridge collapsed under its weight, sending the rocket to the bottom of the river. The intervention of International Rescue saved two technicians inside the command module, but the spacecraft's main body was destroyed.

Ocean Pioneer

Ocean Pioneer was a class of ocean-going nuclear powered tanker which carried liquid alsterine. Ocean Pioneer I was destroyed by an explosion after chemical reaction of her cargo with OD.60 gas in the Mediterranean Sea, there were no survivors. Ocean Pioneer II suffered the same fate, however, International Rescue saved all three crew members. Both vessels featured in the episode "Danger at Ocean Deep".

Red Arrow

The Red Arrow is a fighter jet seen in "Edge of Impact". It has outstanding maneuverability, rate of climb, and speed courtesy of being powered by "twin rockets", which Jeff describes as a "new field". The first two of this aircraft were destroyed by the Hood for General Bron, a military leader from a rogue state. The model appears to be based on a SAAB Draken, dressed up with four extra jet engines. [42]

USN Sentinel

A next-generation United States Navy strike vessel that appeared in the episode "Terror in New York City". It has a top speed of 200 knots (370 km/h; 230 mph), which Virgil described as "phenomenal" when he detected it. The warship is 720 feet long, has a beam of 98 feet, and a displacement of 51,270 tons. Unfortunately, the Sentinel also detected Thunderbird 2 and launched a missile attack, having erroneously identified Thunderbird 2 as an enemy aircraft since it was too slow to be a missile, too fast to be a civilian aircraft and did not match any U.S. military aircraft.

Although the Sentinel was prevented from fully destroying Thunderbird 2 when an identification signal was transmitted at the last minute, the damage sustained to the ship's engines crippled it for the rest of the episode. Subsequently, the Sentinel helped International Rescue to save some reporters from drowning in an underwater river in New York by taking Thunderbird 4 aboard and carrying it near the city, as Sentinel was the only available craft capable of transporting Thunderbird 4 that was fast enough to take it to the city in time to make a difference. [43]

A United States Army walking vehicle that appeared in the episode "Pit of Peril". It resembles a giant beetle. Powered by an atomic reactor, the four-legged Sidewinder has two mechanical arms at the front which are used to uproot trees and move aside other obstructions. The vehicle is operated by a crew of three from the cabin at the front. [45]

At 50 metres (160 ft) long and weighing over 500 tonnes (490 long tons; 550 short tons), the Sidewinder is slow and lumbering, but is capable of crossing terrain inaccessible to other land vehicles. The vehicle was developed to prevent South African "brushfire" wars from escalating into larger conflicts and is equipped with a significant amount of weaponry.

The prototype vehicle fell into an unmapped landfill pit during testing. Due to spontaneous combustion of the rubbish, the inside of the pit was extremely hot. [46] Later versions of it were equipped with emergency anti-gravity generators for use in similar situations or if one of its legs has been damaged.

Skyship One

Skyship One is a large technologically advanced airship which appeared in the second Thunderbirds feature film, Thunderbird 6. Commissioned by the New World Aircraft Corporation, the airship was designed by Thunderbirds creator Brains under the pseudonym of "Mr X". The ship requires only a skeleton crew, as the systems are entirely automated, with destinations pre-programmed before take-off. Key to the airship's design are the gravity compensators; incorporating technology developed for Thunderbird 5 , they effectively reduce the airship's weight allowing it to become airborne. Inside, the cabins and facilities are luxurious and include several themed rooms and bars. [47]


A large, supersonic passenger airliner designed by Brains (although he claims that he only designed some of its new experimental features) which featured in the episode "Alias Mr. Hackenbacker". It is considered the safest aircraft in service, largely due to its unique safety feature in the form of an ejectable fuel tank. In the event of a crash landing, the fuel tank separates from the main body of the aircraft, allowing the plane to land safely with minimal risk of fire or explosion. The fuel "rocket" is then guided to a safe altitude before self-destructing. [48]

Sun Probe

The Sun Probe is a rocket that was sent to collect a sample from the Sun for research purposes. However, the radiation from the Sun caused the retro-rockets to fail, resulting in it going on a collision course with the Sun until Thunderbird 3 was able to activate the rockets by remote.

It first featured in the eponymous "Sun Probe" and (briefly) in the later produced [50] episode "Perils of Penelope" .


A metallic-blue spacecraft that made the first manned landing on Mars. Zero-X first appeared in the first Thunderbirds feature film, Thunderbirds Are Go , and subsequently in the first episode of Captain Scarlet and the Mysterons. [51] [52] It is assembled hours prior to launch and consists of five parts: the Martian Excursion Vehicle (MEV; later renamed the Martian Exploration Vehicle); the main fuselage; Lifting Body 1 and 2, two wing-like structures that are loaded with thruster packs and also incorporate landing gear at the ends; and a reflective nose cone, which attaches to the MEV. [53]

Zero-X is a fictional Earth spacecraft that first appeared in two of Gerry and Sylvia Anderson's Supermarionation productions, the 1966 film Thunderbirds Are Go and the 1967 television series Captain Scarlet and the Mysterons. Although publicity material for the various Supermarionation series, and the TV Century 21 comic, made references to connections between the Thunderbirds and Captain Scarlet canons, Zero-X is the only official link between the two series.

<i>Thunderbirds Are Go</i> 1966 film directed by David Lane

Thunderbirds Are Go is a 1966 British science-fiction puppet film based on Thunderbirds, a Supermarionation television series created by Gerry and Sylvia Anderson and produced by their company Century 21 Productions.
