Me and my family saw a large rectangular reflective craft above our house for about 20-30 seconds.

Me and my fiance went out onto our driveway to do work around the property when she had seen something in the sky and gotten my attention, we both witnessed an extremely large rectangular reflective object move from the left to the right slowly. the craft made zero noise, we have never seen anything even close to this. The size is larger than any plane I've ever seen, we called and made a police report with the Haywood County sheriff's office and were told by the officer that he has also seen strange things recently in the sky. Nearby animal life had gone completely silent when what we saw was closest to us, zero clouds in the sky. The weather was clear, there was nothing obstructing our view and we witnessed this craft or whatever it was for no more than 20 seconds clearly, after that we watched it through the trees and saw its speed accelerate.
