Description (In Witness's Own Words):  I saw an object moving back and forth at a high rate of speed in jerking movements. Definitely not the movement of an airplane. There was no light on object. It was daylight, and I saw no flashing or blinking lights. The color was grey and the shape was square like. I watched it for about 2 minutes and then it left at a great speed straight ahead.

Investigator's Notes: The witness provided a brief, but good description of his sighting.  Given the characteristics described I have neither an explanation nor speculation on what the witness saw.
