A real U.F.O. on the roof.

AFTER RETURNING FROM AN OUT DOOR MOVIE MY BEST FRIEND AND HER BROTHER WENT BACK TO HER HOME TO EAT SUBS.  ALL ATHE KITCHEN TABLE.  SUDDENLY A SWILLING NOISE VERY LOUD CAME OVER THE HOUSE. WE DROPPED OUR SUBS AND RAN TO THE BACK DOOR ,OPENED IT TO SEE A U.F.O. about forty feet above the roof.We were shocked to say the least.It was spinning so fast that the trees in her back yard were folding over.We slammed the door shut and ran to the next room (living room) where her Dad was reading a book and asked if he heard and seen what was over the roof.  He said he thought it was a truck going by on the main street about 120 feet down the road.We called the police dept and reported it.  They said we were not the only ones to call in this report on this night.
Date is approximate.  PD
