Large unknown object observed in Massachusetts town.

For people to notice an object and report it strongly suggests that it was something that they considered extremely unusual. This was a nighttime sighting of an apparently quite large lighted object that one witness described as being at least twice the size of two cars. However, given that it was night, there is no way to estimate the size. The lights were bright enough to startle the witness into reporting the sighting to local authorities. There were no aircraft in the area at the time. Local police declined to investigate.
