OpenMinds does an outstanding job in general. This article is well done. More people should use night vision equipment to video the night sky. It may be that a great deal of previously unnoticed activity will be revealed. Unless these objects are spy craft that are not using FAA approved running lights, they are not only mysterious, their numbers suggest that whoever is here is really out in force. However, be aware that, as the article points out, birds can present a mysterious appearance to an infrared camera. They are relatively easy to distinguish, however, as long as the videographer has a good idea of what they look like using night vision equipment. A video of birds in flight is provided for comparison.
