Safety and tradition

Fouling

When flown pieces catch on each other, on lights or on scenery as they move. Planning the flies is mostly about avoiding it.

Crew

Fly systemThe space above the stage, and the ropes, pipes and counterweights that raise and lower scenery and lights into it.
TrimThe set height a flown piece or batten sits at when it's in position. Crews mark it so it lands in the same place every time.
