Approximately 3 dozen lights traveling in a line. Lights slowly traversed most of the sky, followed by multiple other objects.

My eldest daughter was visiting my in-laws with several of her siblings, when they spotted approximately 3 dozen lights flying across the sky in a tight, linear formation. Other lights circled around the formation in every direction. She took two, short videos of the event. Then, after the formation of lights disappeared in the distance, another cluster of lights appeared about 10 minutes later. Before she could shoot video of those lights, they shot off in every direction at a high rate of speed.
None of the objects made any noise. Some of the lights travelled in rapidly changing directions, and when they dispersed, it was nearly instantaneous.
