Was talking on the phone on my back deck looking up at the sky and just happened to make out a very faint object. i thought it was a gliding bird at first but did no flapping or moving in circle patterns as bird usually will do. like i said i could barely make the shape out, a gray almost see through wing object headed south at a steady rate. no lights. i see plenty of airplanes cross this area of view and it definitely was not that. i then saw another one, or the same, come from the west going east, same rate of speed and looked the same. no sound. i waited around to try and explain it away but they didn't come back.
