Square white and light gray object circling in and out of the clouds.

A large square white and gray colored object was circling in and out of the clouds over Interstate 91. It was not a cube, but a square shaped object with rounded edges and corners, approximately 50’-60’ long on each side, and about 20’ in height. The underside resembled a bottom of a Lego piece consisting of five dark gray circles. The object did not resemble or fly as any known aircraft, and it was far too large to be a drone of any sort. The object was flying in and out of the clouds in a circular pattern, but it wasn’t consistent. It seemed to be a circling in and out of the clouds in a random circular pattern, changing where it entered and exited the clouds, but remaining in the same general area. Almost as if the “pilot” was having fun flying around. This sighting went on for about five minutes as I drove east on I-90 in Chicopee, MA. It was a partly cloudy day at approximately 4:20pm in late November 2021. To this day I’m still trying to analyze what I witnessed that day. I cannot explain what this object was, but I know I’ve never seen anything like it before, and I will never forget it.
