I was walking home as I looked up at what I thought was a airplane flying from my left side but as it across in front of me I realized it was moving extremely fast when i then I thought it was a UFO since the speed was moving too fast and as it started descending to the right I saw it grow a glowing train glow going down realizing it was a comet then it looked as if it fell over or into the mountains to my right of Nanticoke pa. From where I was standing.
