LOOKED LIKE A HUGE CYLINDER BUT ITS APPEARANCE WAS LIKE CRUMPLED ALUMINUM. IT APPEARED TO BE CONNECTED TO A SMALLER SIMILAR CYLINDER

MY WIFE AND I WERE SITTING IN OUR LIVING ROOM BY THE FIRE. IT WAS SUNNY OUTSIDE BUT COLD. SHE WAS ON THE COMPUTER AND I WAS READING WHEN I NOTICED WHAT APPEARED TO BE A LARGE TRIANGULAR SILVER OBJECT OUTSIDE OUR HOUSE. WE HAVE A LARGE PICTURE WINDOW ON THE NORTH OF OUR HOME AND WE SIT ON A HILL. IT CAUGHT MY ATTENTION TWICE AND, AT FIRST, I THOUGHT IT WAS MY NEIGHBOR WORKING HIS FIELD WITH SOME SORT OF EQUIPMENT BUT, THE MORE I THOUGHT ABOUT IT, I REALIZED HE WOULD HAVE TO BE VERY CLOSE TO OUR HOUSE FOR ME TO SEE IT FROM WHERE I WAS SITTING. SO, I GOT UP AND WENT TO THE WINDOW. BY THE TIME I GOT THERE, THE "THING" WAS APPROXIMATELY 400 FEET OR MORE AWAY MOVING EAST TO WEST BEHIND SOME LARGE FIR TREES ON MY NEIGHBOR'S PROPERTY. I CALLED MY WIFE TO THE WINDOW AND TOGETHER WE SAW WHAT LOOKED LIKE A LARGE CYLINDRICAL OBJECT WITH WHAT APPEARED TO BE A PIPE ON THE UNDERSIDE CONNECTING TO A SMALLER SIMILAR OBJECT. MY WIFE COMMENTED THAT IT LOOKED LIKE A PLANE TOWING ANOTHER PLANE WHICH IS IMPOSSIBLE SINCE IT WAS LOWER THAN THE TOPS OF THE TREES WHICH ARE ABOUT A 100 FEET TALL AND IT WAS MOVING ABOUT 20 TO 30 MILES PER HOUR. WE STOOD THERE FOR MAYBE 30-40 SECONDS AS WE WATCHED IT MOVE BEHIND MORE TREES AND THEN IT JUST VANISHED. WE HALF EXPECTED IT TO TAKE OFF OR RISE SINCE IT WAS MOVING TOO SLOWLY TO STAY IN THE AIR BUT IT DIDN'T. OVERALL, IT HAD THE APPEARANCE OF CRUMPLED ALUMINUM AND MAY HAVE BEEN FOLLOWING A CREEK THAT BISECTS OUR NEIGHBOR'S PROPERTY AND CONTINUES ON INTO THE WOODS. IT WAS EXTREMELY LARGE AS AT ONE POINT ITS FRONT AND REAR WERE STRADDLING TWO FIR TREES THAT ARE AT LEAST 100 FEET APART AS IT CONTINUED TO MOVE EAST TO WEST.
