It was dark so the surface was unable to be seen but there were multiple lights in a straight line spaced apart and they were blinking back and forth in several different colors, red blue, green, and white but very bright yet no glow around them. at the first sight, one was gliding across the sky at a very high altitude then drop closer to the earth while moving from west to east and from my position, it was located south west. then another appeared to the north east and it was traveling east to west. then we noticed the first had suddenly just started to move back to the west from the east in the south from my position and the one to the north was moving along a the same speed and direction. the northern ufo was closer to us. maybe a mike or two away. the one to the south was quite far but both had the same lighting differences. when the second appeared, am airplane was passing overhead and clearly the light patern was nothing like what we were witnessing. they glided in silence making no sound. i was nervous but excited at the same time and also my phone was acting wired cause i called my sister whom had just left. she walked outside to go to work after looking up she saw it. the other night the same one was floating in the sky. that's how this all started. we lost sight because they just disappeared.
