While sitting outside my wife and I noticed 7 lights in a v shape moving west to east, totally silent. The lights appeared to be at an altitude that was very similar to what I local airplanes on approach to the Boise airport.

The moon was bright despite being a half moon. The night was calm and there weren’t many clouds. It was a great night for star gazing.
At first I thought it was a satellite but then noticed other lights as it came into view. It went almost directly overhead which is how I could see the v shape but again no sound. The night was strangely quiet.
Lights were white and all appeared to be part of the same craft.
