Thunderbirds is the 1967 British Sci-Fi adventure series created by Gerry & Sylvia Anderson (who would later make the more serious sci-fi series Space:1999) in which all the characters were marionettes (labeled as "Supermarionation").
The series tells the adventures of the Tracy family, a widower & his 5 sons who run a secret organization called International Rescue that performs rescues from hazardous situations whether the disaster is caused by man, machine, or even nature.
Despite it's campy appearance, this was 1 of the best syndicated kid's shows ever to hit American TV, long before the advent of Japanese animation.
And as a proud fan since i first saw this show on Chicago TV back in the 1970's, it gives me a thrill every time that famous Thunderbirds theme right after the opening countdown & that famous line: THUNDERBIRDS ARE GO!!
