The Spectrum Helicopter is a bulky blue and silver aircraft. It offers rapid transportation over short distances for Spectrum members and remains substantially unaffected by air turbulence. It has a crew of one, and can carry at least four passengers; the helicopters had some weapons in case of attack, which included a machine gun.
The Mysterons took over Helicopter A42 in "One Man Fate Has Made Indestructible," meaining it to pick the Captain Scarlet likeness and World President James T. Younger up from atop the London Car-Vu Sky Park Tower, but it was instead destroyed there. It is not specified what happened to the original helicopter's original crew.
