I may have an outlet for you. I am part of the Experimental Airplane Association - EAA. Many chapters have newsletters that they send out monthly or quarterly to their members. They are usually also very interested in content. Perhaps you could write an article, describe in detail how to spot this from the air, include some pictures of what it looks like from the air, and contact the local chapters and ask them to run the article. While it may be true, I would caution against putting in too much graphic-type language into the article. That can stop a reader from finishing the article. You would have to contact each chapter individually, which would be very time consuming, but if this is your mission, I imagine the work would be worth it. Chapters can be located here: http://www.eaa.org/chapters/locator/
. If you click through to the chapters, they usually have an email contact, and if not, there will usually be a contact form on the chapters website.
