'aircrewman' originates from the combination of 'air' and 'crewman', where 'air' refers to the atmosphere and 'crewman' refers to a member of a crew.

'aircrewman' evolved from the term 'crewman' with the prefix 'air' to specify the context of aviation.

Initially, it meant 'a member of a crew', but over time it evolved into its current meaning of 'a member of an aircrew'.
