'The time was after 7:30 p.m. and we suddenly heard the dog, in the back yard, bark incessantly. We thought there had been a break-in and we went to look. Since there was no one about, we stayed outside chatting. Suddenly we noticed a blue light in the sky making abrupt ascending and descending movements. We thought it might be an airplane, but I remembered that these use three lights: white in front, when they are about to land, and red and green at the sides. This wasn't a plane; it was a UFO.'
