I witnessed the object hover. it's difficult to gauge the distance out size. it was black and circular or spherical. i didn't hear any noise. my husband was driving and the kids in the back seat also saw it. i immediately started recording because we often see strange things in the sites while driving the 347 and i never seem to get my phone out in time. finally i have clear video! hopefully some day we will have answers to what is going on in the sky over maricopa.
