Bright Light travelling over Houston Ship Channel, with Red and Blue Lights flashing around the perimeter, making Que-ball turns.At approximately 3 AM, 12/21/02, I walked out on the front porch to smoke a Cigarette, and, glanced up toward the NW to check the sky. My attention was instantly drawn to a brightly lit object travelling toward the NE at about the speed of a private plane, approximately over the Houston Ship Channel, about 2 miles away. It had just passed a yard light slightly above my neighbors house, and, I watched as it travelled the full length of the roof ridgeline (about 150 feet distant, and, possibly 50 feet of roof). Casually wondering why I was looking into what might have been a Landing Light, if the craft were travelling toward me, I was startled to see it make a 180 degree Que-ball turn, without dimenishing its speed. It retraced its flight path back to the point where I originally noticed it, made another Que-ball turn, and, continued on its original path, but, descending below the ridgeline and out of sight at about the point where it made the initial turn.It was simply a large, bright light, larger than a pinpoint, with red and blue lights flashing around the perimeter, yet, the light always seemed to be pointed straight at me, indicating that it was radiating in all directions, as opposed to being a beam that pointed toward the line of flight.This is not the first time I have seen lights in the Sky that seemed to be shining directly at me, while travelling in directions at physical odds with Landing Lights. The first time was in Dec. of 1999, multiple objects over Ellington Field and Baybrook Mall, in Clear Lake City, Texas. Disappeared up I-45, around downtown Houston, and, apparently switching to I-10 West, toward San Antonio.
