I was walking down the road with a couple of my friends in thornridge. i happened to look just over the trees to see two objects sitting in the air. at first i was unsure of what i was looking at and then it hit me this object may be a ufo. as soon as i grabbed my phone to take a video i got chills and the object started to move as if it knew i was looking at it. i took a 50 second long video of the craft before it disappeared behind the trees. a few minutes later i saw two more of the objects but did not get another video.
