What key event marks a turning point in Dahl’s military career?

The key event that marks a turning point in Roald Dahl's military career is his plane crash during a flying mission. This incident is pivotal not only because it altered the course of his service but also because it had profound personal consequences that led to significant changes in his life. After the crash, Dahl faced a long recovery process, which ultimately shifted his focus away from active combat and towards writing. This is particularly relevant in understanding his later works, where his experiences in the war played a critical role in shaping his storytelling. The crash also serves as a dramatic moment that highlights the dangers of war, adds depth to his character, and illustrates the unpredictability of life in the military.
