Saw what i thought was a plane moving in sky in different direction than normal flight path and then saw another following very close behind. stepped outside and saw 15 to 20 moving objects, following each other in straight path but at different spacings between them. some were closer to others, some had more space between them, but all were way too close to be planes. no sound. long line of them kept moving from west to east. tried to video but they were really high up.
