Here is a video of UFOs flying over Indian Head, Maryland (USA), recorded on Saturday, May 28, 2011.

Rob, the author of the video, added these comments :
“The balls of light were glowing orange, kind of like pulsating. But for some reason the color orange or the pulsating didn’t show in the video.
There were 6 of them, but I only captured 4 on my crappy cell phone recorder.
There has been nothing on the news about it or anything. I know what I saw with my own eyes, I have never seen anything like it.”
