Other over Bartow, CA

The report, as filed

A Grey Cube shaped craft (Diamond), about 50 feet tall, and wide, was flying past the above airplane level, and at completely unnatural speeds, during 9:00 am I was about to go inside my house, and I felt the need to look in the sky, I first thought it was a plastic bag, but after seeing it fly above the clouds at speeds that no plastic bag could ever hope to go, I realised what it was, a craft around 50' tall/wide, it was basically joyriding going in directions it logically should not, but still maintaining a direction towards east. It effected nothing, no sound was emitted, no magics; the only thing I could say it that it could have made me look at it threw "mind control", and thats a stretch. I could never describe it as perfectly as I seen it, but I know it was a big, grey, sky-diamond, and it should not exist. Witness elects to remain totally anonymous; provides no contact information.
