"... lasted too long in the sky."
And just how long is too long? Debris coming in at a low angle will leave a distinct and long lasting trail.
The UFO's I saw, lasted over one minute (by my best guess) in the sky. There were TWO bright objects leading the pack, flying side- by- side, with about 10 or so trails following. There was about 7 trails behind one of the leading objects, and and 3 trails behind the other object. These trails were spectacular in color. They traveled along the whole route of the leading objects, spewing out these tremendous rainbow of colors the whole way.
I would sure like to know the size and material make-up of space "junk" that would cause this beautiful sight.
