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 live north of the san antonio airport so am very familiar with how airplanes look. what i saw was not an airplane at a distance. then i thought it was a satelite but it was bigger, brighter, and moved faster, then it disappeared. i did in fact see both a plane and a satellite shortly after both of which confirmed what i saw was neither.
