Witness statement:

Our family was dining on an outdoor balcony of a restaurant. We noticed an enormous hawk on the roof of a nearby building. We took some pictures with our cell phones. One of the pictures showed a disk like object in the background. It is odd that none of us actually saw the object, it only showed up on the one digital picture.
