Light flew the entire night sky above Lake Superior in 2-3 seconds.

Shoot I wish I knew this existed before today!
Sometime between August 5th - August 29th in 2021 my dad went down to the beach at our family camp to look at the stars. It was a beautiful clear and still night. We weren't down there for long when we saw a light that flew the entire sky from south to north out at our camp on Lake Superior at Horseshoe Bay in Ontario about 2-3 seconds. (We have a huge open view of the sky from the edge of the Lake). It was a white light like a plane. There was no noise. We both watched it and I said "what was that?" My dad said he didn't know but that whatever it was was "dangling" and that it must have been military. I said no way that was a UFO. We both remarked that we'd never seen anything like it before.
