Final answer:
A Site Controller is not a position on the flight crew for the operation of the Skycoaster.
Step-by-step explanation:
The subject of this question is Employment and Human Resources. The question is asking about the positions and roles of a Site Controller and the flight crew for the operation of the Skycoaster.
In this case, a Site Controller is responsible for managing the overall operations of the Skycoaster and can fill any position during the operation. However, being a Site Controller itself is not considered a position on the flight crew.
So the statement 'Being a Site Controller is not a position on the flight crew' is true.
