Triangular, silent, motionless totally flat black craft with front facing light beam.

Traveling north on Vinita Street 1/4 mile north of Allen Road.  Night sky was clear with bright stars but dark due to new moon. Air was warm and wind was calm.  We pulled over on the west side of road to allow a passenger to relieve himself and I decided to stretch my legs. I was looking at the stars when I noticed a dark spot over the horse pasture on the east side of the road. As I looked closer, I noticed that the void was triangular. I asked the other three to look in that direction and we became alarmed as we realized that the total blackness was totally motionless and silent. No way to judge it's altitude but it seemed to be about 400 feet up which would put the dimensions at about 150 feet wide and 180 feet long. We looked at it for about 3 minutes and then noticed a feeling of a soundless resonance in our chests that was like a breeze but also like a vacuum and just then the perimeter of the triangle seemed to start glowing with many dots of a red-oran! ge color. The dots were numerous with approximately two to three dot widths between each dot. *  *  * The craft began to tip upward maybe 5-7 degrees and there was a single sound kind of like an electrical breaker and two front facing headlights began to power up. Not unusually bright at first but gradually becoming so bright that you could see the well defined beam for miles in the night humidity. The north facing craft gradually crept forward only a few feet as the speed seemed to increase log rhythmically. It was about 300 feet ahead when we jumped back in the car and followed. It went about 2 miles and turned 90° left at about 80 mph. We turned left on Grand View Road and followed for a mile by which time the craft seemed to be 20-30 miles away and all we could see was a twinkling light heading west toward Tulsa. There seemed to be a trail behind the craft like the one I saw behind the space shuttle years later as it streaked across Texas toward Florida.  After the initial left turn, the craft maintained a constant course but the original elevation seemed to lessen to ab! out 3°. We then drove off after agreeing not to discuss any talk of our encounter or of UFOs with anyone ever.
