My brother and i had just walked out the front door of a friends house. we were talking about the movie we had just watched. as i stepped off the porch i looked up and saw three grey trapezoidal shaped objects floating silently across the sky. they were about a half a block away and maybe 50 or 60 feet high. i told my brother to look and he let out a few choice expletives. having grown up on navy bases all over the world, my brother and i are used to seeing both military and civilian aircraft. these three objects were neither of those. they seemed to be about 50 or 60 feet across. the street lights from below were lighting up the undersides. no visible markings could be seen on any surface. as they drifted by, they may have been moving at ten or twelve miles an hour. then with out any noise they took off in a streak towards the west .My brother described it as ludicrous speed. they appeared to be directly over hypoluxo road during the whole event and looked as if they were gaining altitude as they streaked away. my camera phone was in my pocket but i forgot to use it being stunned by what we were seeing.
