I was in the front yard of our home videoing myself shooting a blow dart gun. out the blue sky, i noticed white objects appear in the sky suddenly that i thought were geese. they didn't act like geese after further inspection. the objects were white triangular shaped that appeared out of the cloudless blue sky. i thought they looked funny but i wasn't sure what i was observing. they came down and moved to the north then back southeast. i quickly said that is the weirdest thing i have ever seen! the objects moved suddenly around in a clockwise, swirling fashion. they remained close together for a few seconds, but then they formed a perfect triangle with one behind them. after doing this they disappeared into thin air. there were no clouds in the sky at the time of filming. in the video, the objects are in the very top of the screen around 30 seconds in the video.
