I was riding my 2006 Suzuki Burgman 400 to my part time job riding east on a Landis Valley Road approx. at 11:30 pm. To my right were apts and to my left was a Church I was planing to turn left into the church to do some custodial work. In front of me was a bridge that crossed over Rt. 222, a major highway. Ahead of me at the 12 0'clock position above the trees was a big ball of light that was descending rapidly and it disappeared below the tree line. I estimated it to be approx. about 1 mile away max. It made no noise and there was no sound of a crash. It was no aircraft of any kind. It was not any kind of firework. It was no bird of any kind. It was not a hot air balloon at all. I have no idea what it was at all. There is the county airport about 4 miles away. There was no aircraft flying around that I could see or hear. When I parked my scooter and went inside the building I was listening for any kind of emergency sirens that might be in the area, but there was none. I did not bother to investigate it.I was a very odd situation. A big ball of light that was descending rapidly that made no noise and there was no crashing sound. I could not identify what the object was. There was no emergency sirens at all after the event. So what ever it was did not crash or land. The event did not last long.
