I at first thought it was an airplane passing over the sky then i noticed anothet in line behind it. as i watched another light appeared and then anothet and another. i stopped counting at 15 but they were in a straight line with the same amount of distance between them. there was no sound. i returned into house and looked out big window. two had stopped and were sitting side by side then i looked over the sky and saw two others had stopped and were sitting side by side in the same position. i could not see if there were anymore in that pattern.
