Fast moving UFO craft seen on clear day in sky

I was driving home from work on a local road near old Camp Kilmer in Edison, when I noticed a fast moving UFO Sighting high in the sky. The time was approximately 5:40 p.m., the weather was sunny and the sky had large, fluffy clouds. The UFO moved very fast, looked disk shaped with a dome, and was a bright, white metallic color. The speed and movement didn't seem like a plane. It flew very smooth and faster than any plane I've seen. I did not see any aircraft wings or blades like on a helicopter. I continued watching it fly northeast for about a minute, while still trying to pay attention to the road. I couldn't stop looking at it as it just seemed so strange and fascinated me.
I wanted to try to take a picture but could not safely pull to side of road. Incident happened quickly and not enough time to get phone and take photo. source nuforc.org
