Wind energy development in North Carolina and adjoining states can adversely impact Seymour Johnson AFB aircraft utilize low-altitude training airspace. This report, prepared by the 4th Fighter Wing based at Seymour Johnson AFB, assesses the impact of wind projects sited within or near military low-altitude training airspace. The conclusions of the report are provided below. The full report can be accessed by clicking on the link(s) at the bottom of this page.
This revealing letter to the FAA documents a clear pattern of political pressure on the FAA to rush the review process of Cape Wind thus creating a possibility of threats to air safety and national security. A portion of the letter is provided below. The full letter can be accessed by clicking on the link at the bottom of this page.
Installation of wind turbines on a property in Sarnia, Ontario will result in the insurance company deny coverage due to potential liability losses. The text of the letter appears below. The actual letter can be accessed by clicking on the link at the bottom of the page.
Dr. Mauri Johansson, MHH, a specialist in community and occupational medicine, delivered this speech at the general meeting of Vestas on Thursday March 29, 2012 in Denmark.
On October 28, 2011, the U.S. Court of Appeals found the FAA failed to supply any apparent analysis of the record evidence
concerning the wind farm’s potentially adverse effects on flight operations. The court vacated all 130 determinations of no hazard issued by the FAA. An excerpt of the court's ruling is provided below. The full order can be accessed by selecting the link(s) at the bottom of this page.
Travis Air Force Base midair collision avoidance pamphlets (MACA) from 2007 and 2011. The 2011 pamphlet was amended to address the impact of spinning turbine blades on radar. Both pamphlets can be downloaded by clicking on the links below. The third 1-page document shown below is taken from the 2011 MACA.
This short paper prepared by Professor Terry Matilsky, Department of Physics and Astronomy at Rutgers University, explains how ice or other debris flung from a turbine blade can travel significant distances.

On January 10, 2011, at 1057 Pacific standard time, a Rockwell International S-2R, impacted a meteorological tower (met tower) during an aerial application on Webb Tract Island,
Oakley, California. The airplane sustained substantial damage and the pilot was killed. The met tower was erected for the purposes of planning a wind energy facility. The preliminary NTSB report can accessed at the link(s) below.
This paper explains how wind turbines located near radar installations can significantly interfere with a radar’s ability to detect its intended targets. The authors explain software tools capable of calculating the radar cross section of electrically large objects. In this paper, interference from wind turbines is predicted using XGtd simulations and new post-processing algorithms that calculate Doppler shift quantities based on points of interaction with the rotating turbine blades.
This document details OSHA violations at the Vestas blade manufacturing facility in Windsor, Colorado. Safety and workplace violations are not unique to this site. Vestas was also cited for workplace violations at overseas factories. These violations date back to April and May, 2010.
