Brightly illuminated orb near I-35 and 635 in Dallas at 3 am 11/29/08 Brightly illuminated orb appeared near eastbound Highway 635 between I35 and Dallas North Tollway just after 3am. Because it was very dark and rainy, I was travelling around 45 mph. I noticed an extremely bright light that appeared to be emitting from a glass office building on the south side of the highway. It was so bright that I had to squint, and I assumed it to be some sort of spotlight affixed to one of the lower floors of the building. The light began to flash arhythmically then stayed illuminated and moved rapidly and diagnonally from the lower left side of the building to the upper right side of the building, then it flew toward the west (the opposite direction I was travelling), zooming very quickly directly over my vehicle, perhaps 8-10 stories above the ground. Entire sighting lasted only a few seconds. My radio was turned off because my daughter was asleep in the car, and I heard no sounds coming from the object and saw no propellers or wings. It was not a large object, perhaps the size of a basketball. Immediately after, a street lamp in front of the building extinguished.
