I don't talk about this very often, but it has been heavy on my mind lately. It has been over 12 years now, but the experience is still so vivid for me. I was on the deck at my parents house relaxing under a starlit light in their hot tub. I was just sitting there, when suddenly the jets in the hot tub turned off. I reached to turn them back on, when I looked up to see this huge...enormous shadow coming over the treeline. It moved so slowly, yet so deliberately.....at about 2mph. I stood up and stared straight at it...It sailed through the sky directly above our back yard without any kind of noise. At the time I wasn't really afraid. I watched as it filled most of the visible sky between the trees in the back yard. There were bluish/whitish lights on the bottom of it, but they were not very bright. As it left, the hot tub jets turned back on and I just sat there in disbelief. I think that I wanted to believe that it was just some military experiment out of nearby Pease Airforce Base, so I really never talked about it to anyone other than family.
