Primarily piloted by Alan (John Tracy if it's Alan's turn to monitor Thunderbird 5), although Scott Tracy co-pilots. Since John is usually seen in Thunderbird 5, he is rarely seen piloting the spacecraft (only in The Mighty Atom, 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, The Impostors and Ricochet, as well as escorting Zero-X briefly in Thunderbirds Are Go.

  • It is rare that Thunderbirds 3 and 1 are used at the same time which allows for Scott to co-pilot Thunderbird 3, and Alan to pilot Thunderbird 1 if Scott is unavailable.
