Two of my friends I grew up with came to visit me from Pittsburgh, which is about 25 mins south of Fawn Township Pa. When night fell, we decided to have a bonfire along with my fiancé at the time, his friend, and my Dad stopped by. Yes we were drinking by the bonfire. My Dad decided he was going home, and we all decided we were going in for the night to all go to bed. My dad had just left, and my best friend and I were walking up the hill together, my fiance, his friend and my other best friend in front of us. While walking up the hill, my best friend and I happened to look into the sky above us at the same time. Everyone else continued on walking and talking. They didn't even notice that the two of us had stopped in dead silence staring at the sky. For about 30-40 seconds, we watched the sky without saying a word to each other. We witness an white orb, glowing orange move slowly across the sky, and it had no sound, was silent as can be. Since Fawn Twp is a pretty rural area, with valley and a lot of forestry, we watched it come out from right above the treeline and it continued over to the next set of treeline about a quarter to a half mile in distance, and it disappeared in front of our eyes, it seemed like forever, then right after seeing the orb, we watched a small aircraft go after it, that also disappeared over the treelines and we then saw a huge flash of light that lit up the whole night sky. Out of the 5 of us there, we were the only two to witness it. I still, until this day wonder, if anyone else in the area saw what we saw. I have heard reports from friends of UFO's seen in the area, one area being West Deer TWP, which is very dark and rural at night, and what they saw was an enormous craft with all different color lights blinking, it scared the shit out of them and they ran.
