My boyfriend and I were at his backyard on his nephew's trampoline, talking and enjoying the stars that were appearing in the twilight. My boyfriend hasn't got the best eyesight because I pointed out a dim lit star and he couldn't see it. Next was a bright light that my boyfriend couldn't see as well. With the random light came a thin triangle which was hard to see but just managed to tell the shape, it was like a paper plane if you saw it from the bottom. The light and the shape moved North from South in a slow-ish pace, but a bit faster than a passenger plane.I yelled out to my boyfriend whilst pointing to the light and following every move "look, look that light, its so bright, its moving, that's not a star. ARGH its gone its gone didn't you see it?!" Turns out he didn't see the craft.The light shrunk and disappeared as if it was a dying touch. As well the thin triangle shape, as if it went on some invisible thing. As well this shape didn't make a noise. Also the location I live and the location I saw this craft is 2 hours away from the nearest domestic airport. There is rarely any air traffic, if there is, it is mostly helicopters.
