On my way home with another witness when the object was first spotted through an open moon roof in the vehicle we were traveling in. Driver actually stopped the car in the middle of the residential street we were traveling through in order to observe the object for a brief moment before proceeding to pull into a nearby driveway.The object continued to travel in a South/East direction, continuously blinking in a strobe-light effect fashion as it flew by at a rather rapid rate of speed. A second identical object flying a short distance away behind the first object was also observed.Both objects presented similar strobe-light effects as they flew through the sky, disappearing and reappearing as they flew past. Myself and the other two witnesses present (a third joined shortly after we pulled into the driveway in question) initially thought the objects we were observing in the distant night sky were perhaps a pair of helicopters or planes. After several minutes of observing the objects, however, we noticed that neither object made any noise whatsoever, and that while they did appear star-like in appearance, they were moving too rapidly and blinking too oddly to be either a star, meteor, or plane of any kind.The witnesses to the event continued to observe the two objects in question for about 10 minutes before they flew out of sight in the distance behind a cluster of trees.
