Looking up towards the north,we saw a V shaped formation of lights. Maybe it was just one craft with a line of 8 to 11 lights in the shape of a V. It was moving fairly slow and headed south. It made no sound but we did feel a cool breeze as it traveled by. We estimate it was about 500 ft in altitude, and maybe 100ft from wingtip to wingtip. We did not loose any time.but neither of our watches ever worked right again.
