What action does the Assistant Controller take if flyers are likely to exceed the vertical swing?

In situations where flyers are likely to exceed the vertical swing while on a Skycoaster, lowering the landing pole is the appropriate action for the Assistant Controller to take. This adjustment helps ensure that the landing area is lower, facilitating a safer descent and reducing the risk of excessive swing. By lowering the landing pole, the dynamics of the swing can be better managed, ultimately helping to protect the flyers and ensuring an overall safer experience. Additionally, other options such as releasing the flyers immediately or waiting until they pass the vertical can pose high risks, and increasing cable tension would not address the issue of the excess vertical swing effectively.
