This chapter serves as a prefatory note clarifying that while the book draws inspiration from real events, the characters and sequence of events are fictionalized. It emphasizes that the story is not a direct depiction of the actual developers of the Ground Controlled Approach radar system but is meant to honor their dedication and skill. The author sets expectations about the blend of fact and fiction in the narrative.
Alan undertakes a month-long aerial tour of British airfields to plan the installation of Ground-Controlled Approach Devices (GCD), gaining experience and witnessing the realities of wartime operations, including bomber missions and innovative technologies like FIDO for fog dispersal. Upon returning to St. Erryn, he observes the large-scale FIDO installation and its dramatic test, while also navigating his increasing responsibilities and personal relationships. The chapter explores Alan's growing awareness of war's harshness, technological advancements in aviation, and his evolving role within the RAF.
In this chapter of "Glide Path," Squadron Leader Strickland inadvertently damages a crucial radar reflector used for guiding aircraft approaches, leading to a dangerous misalignment of the glide path system. Corporal Hart discovers the missing marker and improvises a solution by having LAC Jackson cycle along the runway to provide a moving radar echo, allowing the system to recalibrate and safely guide the incoming aircraft. The chapter highlights the critical importance of precise ground-based navigation aids and quick thinking under pressure during adverse weather conditions.
In this chapter of 'Glide Path,' the aircraft C Charlie attempts a landing approach complicated by a malfunction of the ground-controlled approach system's Mark I antenna, which becomes jammed due to a broken gear tooth. Despite the loss of most radar coverage, the pilot and controller coordinate a difficult maneuver to keep the aircraft on a limited precision approach sector, highlighting the tension and reliance on technology and human skill during critical landing operations. The chapter also explores Alan's reflections on mortality and faith amidst the high-stakes environment.
