Seen by 2 people in Missoula, Montana, at approximately 23:50 there where 3 fireball looking crafts hovering with no sound.I was rocking my son to sleep, when I looked out the window and saw 3 dark orange red in color circular crafts hovering over the mountain top. I told my wife to turn around and she did and asked what they where. I said I didn't know and we went out side to get a better look. There was no sound in the sky and the 2 just hovered while the one on the far left rocked back and forth from left to right than after a couple minutes it disappeared. The one that was in the middle started moving up and down than with great speed it disappears and the one on the far right just vanishes right there my wife took a video.
