Okay, for those out there who are Gerry Anderson fans, here's one:
UFO (pronounced you-foh in the series) featured a top secret agency dubbed the Supreme Headquarters Alien Defence Organization, or SHADO (shadow) for short. Taking place in 1980 and beyond, in 1996 it evolved into the Global Defence Command, according to published "history." A new series tentatively named UFO 2 was to take place in the year 1999, with Moonbase greatly expanding in size and abilities.
UFO 2, however, was never made. Name the show that did replace it.
As a bonus, name the heavy fighter craft that were supposed to replace the short-range SHADO Interceptors. (And yes, it did exist.)
