Sighting was in southern Maine. I was in my kitchen getting ready for work around 3 and heard a loud rumbling, almost like the combination of thunder and dragging a trashcan on a driveway. Nobody is up in my neighborhood at this time.

As I walked out to my truck I noticed the sky was very clear. When I looked up I noticed a light traveling across the sky then I noticed another one and another probably about 7 in total. It’s not uncommon to see planes in my area expect all these lights we’re traveling in a direct line across the sky almost in a formation like manner. Could of been helicopters but the spacing seems too far to be any kind of military exercise and I don’t believe there is an aviation unit around here.

Anyone see anything like this before?
