Charles Gaylion, sent to train new pilots in the south of England, quickly becomes frustrated at the rules that forbid him teaching the trainees anything potentially dangerous. His ideas for a new training system are dismissed as nonsense by his commanding officer, who will not allow new pilots to fly, alone or accompanied, in the slightest adverse weather conditions. Charles does, however, find a home from home at Becket’s Hill, where he begins to visit Molly and Lorna on a regular basis. Molly still has some hope of Alan being found alive, but Lorna feels sure that she will never see him again. After an argument with one angry flying pupil, Lt Towy-Jones, who questions his courage, Charles demonstrates how to get out of a spin, allowing the trainee to try it for himself even though it means risking both their lives. However, a less able pupil, Westerley, hearing about his friend's success, decides to take a plane up alone and attempt the same manoeuvre, while Charles is off the base taking Lorna up for a pleasure flight. Westerley crashes and is killed, but, when Charles attempts to take responsibility for the incident, he receives unexpected sympathy from his CO and is not blamed. At the end of the episode, the viewer catches a glimpse of Alan Farmer, semi-conscious and being cared for in a private house. (thetvdb.com)
