My family and I were driving home from eating dinner on Rt 44 in Seekonk MA. I was driving and my 16 year old daughter was the first to witness the object. She asked me what it was and I first thought it was a helicopter. It was to my left so I slowed down and knew very quickly it was not a helicopter. My wife and oldest daughter all saw the same thing. A black triangular shaped object hovering and moving unlike any aircraft I have ever seen. It has very bright lights on its undercarriage in each corner. When I pulled over to turn the vehicle around and get another look at it, the object was gone and there were no signs of it, or any lights in the distance. We had the windows down and were close enough that it was odd because the object was silent. I was driving so I couldn't take a picture but to be honest we were all mesmerized by what we saw. My wife is the biggest skeptic and saw exactly what I saw. She thinks it was a drone. This was no drone. Military craft maybe. Extraterrestrial maybe. Either way it was a black triangular shaped silent object with bright lights in each corner that hovered and moved unlike any aircraft that I have ever seen or heard of. I wish we were able to get a photograph of it.
