UFO Sighting in Quakertown 4-28-2014

When I first noticed the object I thought it was just some tower with lights on it. Then I realized that there is not tower there because I always drive down that road. My next guess was that it was a helicopter since it was just hovering in place. The closer I got the greater my suspicions were. There were two white lights that began to blink a couple of times so then I just thought it was a commercial airliner because of the lights and the face that it was not making any noise like a helicopter would. The closer I got the more I realized that it was way too low in order for it to be a commercial jet, also it was hovering and planes do not do that. Out of no where it took off, not too fast but fast enough that it was past the horizon within 30 seconds. It seemed like it went from 0 to 60 in a matter of milliseconds. As I was watching it fly away I noticed three orange/redish lights behind it like boosters. I still do not know what it was but the closet thing I can come up with on how it looked like is a space shuttle. I do not know what kind of space shuttle looking aircraft can hover at a low altitude without making a noise and then suddenly take off. I am intrigued by it and also the fact that when I opened the car window to listen to the aircraft that is when it began to fly away. I do not believe in coincidences and for some reason I believe that it heard me as I was opening the window and kind of yelled and said "WHAT IN THE WORLD IS THAT?!" that is when I noticed that it was not a helicopter because it didn't sound like one and it's silhouette did not resemble a helicopter but more of a space shuttle kind of shape.
