September 10, 2004: Several electronic warfare efforts are underway within the United States to increase protection from terrorist attack. Evidence is starting to show up. For example, GPS "anomalies" (unpredictable GPS performance) have been documented by airline pilots and electronics experts near U.S. nuclear facilities. I would think that this could be highly probable. With the abundance of civilian GPS devices, ability to covert to targeting function such as our new bombs increases.
