Larry, I agree with your bomb dump assessment, its on the perimeter. Also the US Army field manual states that herbicide spray has a 500 meter coverage area, that extends the perimeter a good margin (1640 feet).
Ken Beamer, I have had lung cancer and bypass surgery. My claim was approved a week ago on appeal and I received the award letter this past Saturday. Key is proof that you worked, played or lived on the perimeter (key word "proof"). I used my AFSC (Jet Aircraft Mechanic) and my trips to the trim pad at the end of the runway, FOD walks to that area, buddy letters from Jet Engine Mechanics and Aircraft Mechanics who went to the trim pads, and others with same AFSC. I can only speak to my experience. If I can help let me know, Susie and others were of great assistance to me. LouB.
