We observed 12 red orange lights or orbs as they traveled in smal groups they moved slowly across the sky to our south west to north east direction.We live close to philly and there is constant air traffic as we observed these objects we noticed there were no planes in sky, as i would say the second object was coming my 17 year old daughter called us from the lake which is half mile west of us and she observed the objects with her boy friend and noticed the were coming from south but we're asscending to the sky she became frightened and came home .We all saw same lights orbs .!? they made no sound at all they moved very slow and continued to the north briefly after we noticed the flights returning from philly in there pattern ! my wife looked at flights for philly and they were delays on many flights .What surprises me is the silence of carft and how bright they were ! the red and orange color was almost neon .It was amazing how they gracefully moved across the sky ! this was amazing !
