In Chapter 9 (The New Project Grudge) Ruppelt writes, “UFO’s were seen more frequently around areas vital to the defense of the United States . The Los Alamos-Albuquerque area, Oak Ridge , and White Sands Proving Ground rated high. Port areas, Strategic Air Command bases, and industrial areas ranked next.”
