Gerry & Sylvia Anderson's UFO. Series Guide, Volume One

UFO was the first live-action series from Gerry and Sylvia Anderson, makers of Thunderbirds and later Space:1999.
UFO. That weird sound echoing and whooshing and whispering ominously from the speakers of your television set!
Those bizarre, hard to completely distinguish, whirling, spinning, relentlessly approaching saucers - translucent, glittering, shimmering, dream-like and nightmarish - coming in from the blackest depths of space.
Thus is the unforgettable alien menace that gives name to Gerry and Sylvia Anderson's 1970 magnum opus, UFO.
In this first volume examining the series, Adrian Sherlock discusses the episodes which launch the series and the introduction of Colonel Paul Foster (Michael Billington) and his conflicted relationship with Commander Straker (Ed Bishop) as they head up SHADO (Supreme Headquarters, Alien Defense Organisation) and its efforts to save Earth from the alien menace.
