During WWII, Flying Officer Alan Bishop is reassigned from England’s Northern Coastal Defence to a new project involving the development of a new radar-based airplane guidance system called Ground-Controlled Descent (GCD). Its purpose is to guide military craft to safe landings during dense fog or inclement weather. Along with a team of soldiers and scientists, and a trio of Women’s Auxiliary Air Force operators, Bishop leads the testing of the GCD in both staged exercises and actual landings in a small airfield near Land’s End in Cornwall.

Arthur C. Clarke’s only non-SF novel, Glide Path was inspired by his participation in the development of Ground Controlled Approach (GCA) during his wartime service with the Royal Air Force.

Such a topic alone does not constitute interesting fodder for fiction, and at times, I was reminded of Clarke’s Prelude to Space, a fictional chronicling of man’s first mission to the moon in the late 1950’s with little in the way of plot or conflict.

Much of the conflict in Glide Path remains in the background and stems from Bishop’s concerns over the declining health of his father, his feelings of inferiority compared to the brilliant scientists and skilled pilots on the team, pressure from skeptical generals, and an adversarial relationship with one particular RAF pilot who becomes competition for the affections of a local harlot.
