I just noticed that there are still people coming back to view this thread! The discussion has been good. One theme I saw over and over were aircraft moving close to a number of communications towers that were about 6 miles away. Above in this thread I shared a photo of an aircraft flying into the forest near a tower. I have other photos of aircraft coming up and out of the trees and flying off near a tower.

In the first two photos below was an aircraft that I saw several times. In the photo it is moving right to left toward a tower.This is likely a 2 second time exposure. The second photo is an enlargement of the aircraft. To me, it looks like a delta shape or perhaps a triangle? The third photo is just an interesting type of aircraft I saw numerous times. Why these aircraft had such bright lights, which were not conventional navigation lights, is a mystery. Wouldn't this bright, unconventional lighting draw attention? Is that what they want? One more comment about the third photo. Don't presume that you see the entire aircraft there. I sometimes saw lighting change suddenly to imply a different size or shape.
