What happened at Sheffield Bridge Covered in 1969?

''Fifty years ago, the old bridge was still in use for vehicular traffic. On September 1, 1969, nine-year-old Thom Reed drove with his mother, brother and grandmother across the bridge.  After crossing, they saw a bright light rising out of the Housatonic River.  Soon after that, Mr. Reed remembers being taken from his family’s car to large building that looked like an airplane hanger.  Large, insect-like creatures walked around the building.  Mr. Reed ended up in a room in the building, and then he remembers being back in the car with his family shortly after that.  Apparently, everyone was seated in a different spot in the station wagon.  Mr. Reed thought that the ordeal seemed to last a few minutes, but in reality, two hours had passed.  That night, dozens of Berkshire residents called a local radio station to report unusual lights and loud noises.  Several had spotted a saucer-shaped aircraft hovering in the sky.''
