My wife and I were outside on our deck this afternoon, enjoying the nice weather. We saw a plane and then immediately in the same area of the sky saw a strange object. The object was bizarre in that it had no distinct shape and completely unidentifiable. While still keeping eyes on the UFO, we then immediately observed a 2nd plane pass through the same area of the sky. This second plane that went by during the sighting made us realize how strange and different the unidentified object indeed was. We followed the trajectory of the UFO until it went out of sight. It changed shape so many times that it is difficult to describe the object. The colors we observed were mainly silver, some red and white. At times the UFO would change shape to a tiny ball, then expand back out to other strange configurations. The UFO went basically to the direct east of our home the entire duration of the sighting. We moved down to the yard toward the end of the sighting to get a better view between the trees. Eventually we completely lost sight of it in the blue sky to the east. When we returned to the deck, we saw a third plane pass through the exact same area of the sky where we had originally seen the UFO and the other 2 planes. Unable to obtain a decent picture, given the brightness of the summer sun and height of the object and planes.
