Unidentified light travelled in the sky over Belchertown

On July 15, 2016, several persons have spotted and photographed a brilliant unidentified light travelled across the sky over Belchertown (Massachusetts). One of the witnesses has sent his story on the MUFON website.

Witness report:

We were hanging out around the pool when a very bright light caught my attention. 3-4 of us saw it. The light was at approx. 1:00 in the clear blue sky. It went 3/4 way across the sky, then suddenly reversed, and travelled back along the same path. It moved very deliberately, but not all that fast. It did move like a drone might, but it did not (to my eyes), look like one. No sound, and there was no way to judge its size. Please let me know what you think.
