The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
I was walking along the pedestrian path on w sam houston tollway towards briar forest dr where i saw two bright orbs hovering just above the horizon. they often dims out and seemed to be brighter than any other familiar conventional lights or stars and does not seems to match the strobe light/anti-collision beacon light patterns of normal aircraft.
