I'm a health care worker and had just finished client care. went on porch to rest for awhile and looked towards the west when i spotted eight lights in a row in the distance. thought at first i was seeing formation flying but realized the lights never moved from straight line. as the lights came closer i realized i might be seeing a ufo. i wasn't prepared for the size it was, and how low it was. i was also surprised to hear sound. i can only guess at size, almost three hundred feet across. i judged it by the size of land i was on and that it was big enough to fly over the neighbors yard as well. it came in low and not fast. it was hard for me to believe this thing could fly. the metal was dull with no writing. rectangle shape with a cut out in the middle. about five minutes after it came over i could see military helicopters in the west, which flew back and forth like they were looking for something although how they missed this thing is beyond me. i was excited to actually see this but questioned whether this could be one of our whatever it is. it seemed so indifferent to being seen. i noticed that there was a lot of sightings in p.A. around the time i saw this and realized it was probably coming from that area. i just kept watching until i couldn't see it anymore.
