A person who operates a light public carriage or a worker in a theater who handles curtains and scenery.

The word 'flyman' is formed from 'fly' (from Old English 'flēogan', meaning to move through the air) and 'man' (from Old English 'mann', meaning a human being). A 'flyman' refers to a person who flies or operates an aircraft.
Think of someone who 'moves through the air' ('fly') and is a 'human being' ('man') — that's why a flyman is someone who flies.
