Too many people getting access to places they really shouldn't be simply because they maintain a blog or some such outlet. Just like an NFL sideline or Pit Road in racing, a flightline is no place to "play" photographer.
(*AFAIK, ICAS has little or no influence over military open houses...)
I may be reading too much into your post, but from looking at your website you don't do any more than that (maintain a blog and sell prints)either. Am I correct?
I routinely get media credentials to many airshow, motorsports and other events in the Vegas area, and I do no more than maintain a blog, and sell prints from these events. I do, however, offer certain prints back to the granting authority, be it the military or otherwise. I assure you that I don't "play" photographer.
What group of people do you object to being there? Quite honestly, I didn't meet anyone in the media pit that I thought shouldn't be there. Listeing later in the day, there was one guard screening the general public that was not allowing the long lenses. I heard him telling a few people they couldn't bring in their zoom lenses and needless to say there were some pissed off people.
