On this evening, i was sitting on the swing outside watching the sky. it was still light outside. at any given time of day or night, many jet aircraft are easily observed either climbing from or descending to houston airports. from lufkin's sky, all jets departing or arriving in houston are probably at an elevation of approximately 20-27 thousand feet. there were no clouds at all that evening. i observed a jet headed southward from north by northeast. at the same time, from due west, i saw a yellow light orb, with no discernible blinking lights appear approximately 1 mile from the aircraft. it appeared to be on an intercept course with the jet. as soon as the yellow light orb appeared, the jet aircraft had begun to make a discernible turn south which may have just been a course correction. the yellow light orb was moving much faster than the aircraft, and once the plane had executed its course correction, it had aligned itself behind the aircraft. it amazingly and very inexplicably turned at an angle of approximately 40 degrees to the southwest by west. it continued in this direction for approximately 2-4 thousand feet and just disappeared. i do not have facebook, but there are purported local accounts of the same sighting with those folks stating they saw multiple orbs in a line. i only saw one. it behaved so strangely with its speed and movement and abrupt disappearance.
