Rectangular-shaped UFO spotted over Milford, PA

On November 5, 2016, an automobilist has seen a rectangular-shaped UFO flying at low altitude over the city of Milford, Pennsylvania.

Witness statement:

Driving my friend back to his house. I noticed it just above the tree line. A comet but it looked like an rectangular/sphere. It was falling in the sky going slowly speeding up for a couple of seconds then decelerating back to the same pace (repeating cycle). Astonishment. It went below the treeline.
