The show featured the Andersons’ Supermarionation, a form of puppetry first introduced in Four Feather Falls and Supercar and used again in their subsequent productions such as Stingray and Captain Scarlet. Thirty-nine black and white half-hour episodes of Fireball XL5 were made on 35mm film: all future Anderson series were produced in colour.

Several Anderson series have been shown in syndication in the US, but Fireball XL5 is the only Anderson series to have run on a US network. NBC ran the series in its Saturday morning children’s block from 1963 through to September 1965.

A similar programme often confused with Fireball XL5 is Space Patrol, produced by Gerry Anderson’s ex business partner and co-founder of AP Films, Arthur Provis due to a number of similarities and settings.

The plot of the show consisted of Supercar, a vertical takeoff and landing craft invented by Rudolph Popkiss and Horatio Beaker, and piloted by Mike Mercury. On land it rode on a cushion of air rather than wheels. Jets in the rear allowed it to fly like a jet and retractable wings were incorporated in the back of the car. Retrorockets on the side of the car slowed the vehicle. The car used “Clear-Vu”, which included an inside television monitor allowing the occupant to see through fog and smoke. The vehicle was housed in a laboratory and living facility at Black Rock, Nevada, U.S.A. In the show’s first episode, “Rescue”, the Supercar crew’s first mission is to save the passengers of a downed private plane. Two of the rescued, young Jimmy Gibson and his pet monkey, Mitch, are invited to live at the facility and share in the adventures.
