4 lights moving at high rate of speed coming out of Texas Canon North of Fort Huachuca.While driving down I-10 on Sunday night, I saw 4 oval lights moving at a very high rate of speed perpendicular to the freeway.The lights followed each other at very close proximity. I could not hear any noise other than that of my car on the road. There were many cars driving down I-10 at 8:20 in the night. I was traveling westbound, and the lights were moving northbound. The lights were visible for approximately 2-3 seconds. The lights were traveling at very low altitude based on my view, and the mountains around this area (estimation, it is pitch black around that area in the night, Fort Huachuca lies approximately 20-30 miles south of where the lights were seen - lights may have been approximately 15 miles away from F.H. and may have covered the remaining 15-20 miles in what appears to be 2 sec, this should give me a speed, correct 27K mph? ). This was an one of the most exiting things I've ever seen. To describe the shape/size from my view: ovals (based on view could have been round), appeared to be approximately 1 foot wide on the wide section, we should be able to figure out an approx. size based on information given above. Each light appeared slightly smaller than the preceding one, based on distance I suppose. I was driving down from an area called Texas Canon.
