Behind them is a 190-foot meteorological tower, part of the potential Cape Wind site. Federal Aviation Administration officials felt political pressure to approve the planned wind farm, and did so amid internal disagreements over how to ensure the wind turbines wouldn?t interfere with local radar and compromise airplane safety, according to FAA documents obtained by the project?s opponents.
