I was driving home on Swamp Road after leaving Bucks County Community College around 9pm on 1/24/2012 when I observed what first looked like a low flying plane the size of a small jetliner due to its 3 white lights. It appeared to be turning about 30-40 degress. It seemed to be running parallel to Swamp Road. I thought it was odd, it is not in the flight path for Mercer County Airport, NJ. As I drove closer, I thought that it could not be a plane but a helicopter because it was flying way too slow! It was about 300 - 500 ft it the sky, no more than 1/2 mile away. Within the 3 lights there seemed to be interior lights with the structure. I have never seen anything like it. I came to a stop light and rolled down my window as it was passing to take a listen to it ... it was not a jet or a helicopter, it sounded like a electronic humming fan or turbine blades ... I was on a aircraft carrier for 5 years ... no plane I have ever heard. I came home and googled ufo bucks county after remembering sighting years ago. [Link moved to FI section/cms/tg] ... this looks like what I saw but from more of a side view and it was not that high in the air ... The 3 lights were white not red. The strange thing is that MUFON had a meeting at BCCC on 1/24/2009. I have never seen anything like it. I love it.
