It was about 10 pm and i was reading in my 7th floor bedroom looking out toward the airport when i saw a craft different from the planes and helicopters around the airport. i see them every day. it was just hovering over the airport then slowly drifted toward me (i live on the beach) in hovering mode. as it moved closer it tilted and became larger because it was closer. i got a pair of binoculars and could see it was circular. on the bottom of it there were white lights in circular rows on the bottom of what was a circular vehicle. it was not a plane or helicopter and eventually moved away from me in a westward direction and disappeared. on the education part, there was not a category i could check. i am an m.D. and practiced psychiatry for over twenty years.
