At the time i was about 12 and spending the night at my best friends house. her bedroom overlooked backyard which had wooded area behind it. we both woke up to a loud buzzing type sound and looked out her bedroom window to see an object hovering just over the trees approximately 200' away. it was as large as the house, dark silver colored and had round port-like windows all around the edge of it; resembling a typical spacecraft that you'd always see portrayed. we were scared but mesmerized by the lights omitted from its windows in a quick rotation around the circumference of object. it hovered for what seemed like several minutes and then very rapidly shot away until we no longer could view from bedroom window. this happened in mid-late 1960's and i recall the event as vividly today as i did 50 years ago. i didn't know this mufon site existed until my best friend told me about it a few days ago.
