AT APPROXIMATELY 10:30 AM,WHILE WORKING IN DOWNTOWN HOUSTON, I LOOKED UP AT A CABLE POLE THAT I WAS TO WORK ON, AND SAW A VERY BRIGHT WHITE LIGHT, VERY HIGH IN THE SKY. IT WAS THREE TIMES BRIGHTER THAN A STAR. IT WAS MUCH HIGHER THAN AIRPLANES FLY, SINCE I COULD SEE AIRPLANES GOING BY BELOW IT.IT JUST HOVERED THERE AT ABOUT 80 DEGREES TOWARDS THE SW SKY OVER THE DOWNTOWN AREA.IT APPEARED TO BE IN THREE PIECES, A TRIANGLE ON THE TOP, AND A SQUARE IN THE MIDDLE AND SOME OTHER SHAPE, HARD TO MAKE OUT. AS IT SPUN AT A HIGH RATE OF SPEED, I SAW IT THROW OFF SPARKS TWICE, ONCE ON THE LEFT SIDE AND ONCE ON THE RIGHT SIDE.MY FATHER IS A PILOT, SO I KNOW HOW HIGH PLANES FLY, AND THIS WAS VERY MUCH HIGHER, I WATCHED IT UNTIL HIGH CLOUDS COVERED IT. IT WAS NOT A CLOUDY DAY.I WOULD LIKE TO KNOW IF ANYONE ELSE SAW THIS AND WHAT IT COULD HAVE BEEN.THIS HAPPENED THE WEEK BEFORE CHRISTMAS, NOT SURE OF THE EXACT DAY.
