Compared to a plane it was 10 times larger. It had a tail. It appeared to be on fire as it entered and passed through the atmosphere. It stopped burning after it had entered in to our air space and appeared to glow like a hot ember it did not appear to change in size as it passed across the skyline . It dropped below the horizon and it was gone. I have never seen anything pass all the way through the atmosphere and continue to fall to the earth it had to make a large crater some where.
