In Joseph Heller's novel "Catch-22," the protagonist experiences a profound sense of confinement while aboard an airplane. The individual feels trapped, as the only escape is to another section of the aircraft, highlighting the claustrophobic nature of flying. This sense of imprisonment reflects a broader theme of entrapment in the narrative, where choices seem limited and freedom unattainable.

Additionally, Heller introduces an intriguing idea that those who are drawn to air travel may be subconsciously seeking a return to the safety and comfort of the womb. This notion suggests a deep-seated psychological desire for security in an often chaotic and unpredictable world, emphasizing the complexity of human motivations in the face of overwhelming circumstances.
