Recurring sightings of 3 UFOsThree objects seen from southside of pittsburgh. One object appeared to be a bright white light that seemed to dim when planes flew in close proximity, and had two other unidentifiable objects on either side of it. The two other objects appeared to hover, then move in a quick zig zag pattern. These two objects appeared to have red, blue and green lights that appeared to pulsate. Definitely was not a helicopter, commercial airliner or satellite. Viewed these objects for approximately one hour. These objects have been noticed by several neighborhood folks, and nobody has a logical explanation for these occurrences.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
