Moved quick with no noise.Reporting two white/silvery objects heading almost due north about 1.5 mile north o San Antonio, TX airport. Time approx. 10:15am on 08-14-2012. Objects were moving rather quickly at around 1000+ or- feet altitude. I check wind speed, at 3000 feet 12mph. These moved faster than that. No other aircraft was heard or seen at this time.Shape was almost disc shaped, more round. No noise of any kind noted. I watch aircraft fly around all the time, this was not the normal.
