I live somewhat close to an airport. I've heard all sorts of aircraft from helicoptors to fighter jets. The sounds I heard today were not of this earth.
I always used to get excited about trying to see a u.f.o or the idea that there is other life outside our planet....until today.
My wife and I were picking up after the cats, giving them water, food and changing the litter. I heard what sounded like a fighter jet..I didnt think about it much more than that. As we were cleaning I noticed the sound did not go away but it was getting louder. I went out front to see what it could be and there was nothing in the sky except clouds. The noise sounded like a huge wind tunnel or constant flow of air or wind. there was no breeze everything was calm except this terrifying noise from above. It sounded like a huge mother ship was overhead. there was also a steady humming noise.
i cant explain what this sound was....but it was real. I no longer wish to see a ufo and I'm kind of frightened the end of the world is coming soon.
