I was at work and I just happened to look up in skyo this a loknow looking at stars and it was beautiful out and clear so when I looked up I saw this craft it starteled me and it was huge and gray and black just slowly.floating along east to west no sound no light I thought that was strange I got worried that a big commercial jet lists its power and was trying to get to our local airport so I ran down to get a friend to see what he thought and it was gone I still can't get the image out of my head how quite dark huge slow it was floating its driving me crazy maybe 500ft. Or so off ground 100ft. Wide just floating I don't wanna see again I didn't believe in UFOs I don't know now after reading that others have seen this in eastern pa to I just don't know
