UFO WAS SITTING ON THE GROUND WHEN I GOT OUT OF MY CAR TO SEE WHAT I THOUGHT WAS A CHOPPER WITH IT'S LIGHTS ON. AS I APPROACHED THE CRAFT I REALIZED IT DID NOT HAVE CHOPPER BLADES. I WALKED TO APPROXIMATELY 20 YARD FROM THE CRAFT WHEN I OBSERVED WINDOWS GOING ALL AROUND THE CRAFT AND HEARD A ELECTRIC SOUND AS THE LIGHTS BLINKED, I SEEN THE CRAFT SITTING ON A LANDING TUBES OR BARS LIKE THE DIVING BELL IN ATLANTIC CITY. AS I RECALL THE CRAFT WAS SILVER IN COLOR. I RAN AS FAST AS I COULD GOT IN MY CAR AND DROVE 2 MILES TO MY HOME TO TELL MY WIFE. I ASKED HER TO COME WITH ME, SHE WOULDN'T BECAUSE OF THE SLEEPING CHILDREN. I DROVE BACK TO THE SCENE BUT THE CRAFT WAS GONE. NEXT DAY DURING DAY LIGHT I WENT BACK TO THE FIELD BUT COULD NOT SEE HIGH GRASS PUSHED DOWN, TALED WITH PEOPLE LIVING CLOSE TO FIELD, THEY OBSERVED NOTHING!
