there would be a “clear risk of collision with the wind turbine generators.” Attempts to circumvent the turbines would be “problematic because even horizontal diversions of only one or two miles can further compress air traffic into congested corridors.” The “finely balanced airspace over Nantucket Sound is already one of the most congested, foggy, and dangerous airspaces on the eastern seaboard.” with evaluating proposed structures in order to The “encroachment of established VFR routes [would] severely compromise [pilots’] ability to determine if the structures will be “hazards”—that is, obstructions—to air navigation, or to navigational execute collision avoidance maneuvers in the dead or communication facilities.
