Return of the UFO from three years ago?

So, has anyone seen this???? A few days after our blog post about the Amherst UFO sightings three years ago, we received the following reply, about A VERY SIMILAR SIGHTING, this time in Conway, last week. Please share - either we are getting repeat visitations from something extraterrestrial, or there are indeed unmanned fairly sizable drones populating our skies. (Or maybe both!). What do you think is going on?

Here's the posting we got:
"I read this article yesterday (the one by Rebecca Everett) for the first time and my jaw dropped. I am SO happy it was posted!!! I live in Conway, MA, and on 1/5/16, I had an identical experience to what the people saw in Amherst, with a diamond shaped vessel that SLOWLY went over our house, flying VERY low. My husband and I both saw it. I called the Chicopee and Westfield Airforce bases the following morning, which both denied having any unmanned drones. The only reason I called them was because it looked like 2 people could ride in it, or either be an unmanned drone- the size of 2 cars or a small plane. It was around 8:45 at night, and I was watching the fish in our newly set up tank next to our sliding glass doors. My son was sitting in my lap, and I happened to look out the large window of the door and saw lights coming towards our house through the trees. I immediately said "Hey, there's a plane that's about to fly over our house!" I picked up my son (as he loves planes) and opened the door. No sound of a plane. I put him down in the chair, stepped out on our porch, and called my husband over. The thing flew so low, so quietly, right over our garage and mudroom. It had four white lights and was in a diamond shape. It was dark out, but it appeared to have a slightly rounded curve on it's belly that went from one wing to the other from the shadows cast on itself from the lights on it's wings and nose. It happened so slowly, but so fast- I wish I had taken a video or photos of it with my phone! None of my neighbors saw it unfortunately. I had to file a report with the Chief of Police in Conway after discussing the matter with the Air Force base in Chicopee about inquiring with my drone question, which they both denied. My husband thinks they are lying. My neighbors think it's a UFO, and I honestly am just so baffled and obsessed now at finding out what the hell it is/was!"
