On the beach in Mexico I saw a flat oval shaped bright shiny UFO high in the sky which hovered, turned and disappeard after 90 seconds.My friend and I were sitting on the beach at approximately 10:30 am. My friend said...what is that up there? I looked and we both saw a shiny object that was like a flat oval. It was hovering just under the sun rays. We watched for approximately a minute or more and told my friend's husband to look..he couldn't see because a shade tent was blocking his view. When he stood up to look the object made a dip or turn to the left and went straight up and disappeared. My friend practices family law. I am a real estate agent. My friend's husband is a contract lawyer. There was no plausible explanation for what we saw other than it was an unidentified flying object. It was high in the sky and could not have been a relflection of anything.
