This video is REAL based on what the witnesses described the UFO.
The video owner explains what they saw:
My girlfriend and I saw this UFO last night (11-13-07) while we were driving home from San Diego. We were driving up the 5 north. We saw it about 60 miles north of Bakersfield, CA and followed it for probably 30 miles. I shot about 3 or 4 minutes of pretty clear footage. I have a total of 16 minutes of footage as we chased it. I have lightened it so you can see it better in the black night sky. With our own eyes we could see the outline of the craft at times. It had red lights most of the time, but sometimes they would all shut off. The second time that it flew directly at us and over us the lights turned to a white-light blue color. This is definitely not an airplane. It flew right over us twice, about 1,000 feet above our heads and made absolutely NO sound. It just glided through the air. It shape-shifted and even expanded to the size of 4 football fields at one point. It flew side ways. At one point what looked like a comet flew out of it sideways. I didn't get that on video. I've seen lots of shooting stars and they ALWAYS come from the sky. This one flew sideways slowly. Very strange. Pretty amazing. Near the end of the footage it looked like a triangle flying sideways. We are still in shock that we got to see this thing, watch it for so long, and get it on video! I think it is extraordinary.
