Father and daughter witness a triangular craft, w/ lights in corners, streak across the sky E to W.Location: Casselton, North Dakota (north end of town) Date: April 11, 2012; Time: 21:48 I and my 9 year-old daughter were sitting at a campfire in our backyard and looking at the stars. It was a totally clear evening with no clouds or moon in sight. We were looking towards the southeastern sky observing a distance jet aircraft that was moving eastbound. Suddenly I observed coming from east to west a blur or smudge of lights. For a brief instant I thought a group of meteors were striking the atmosphere simultaneously, at least until my eyes become focused better on the blur of greyish-white lights. When my eyes were focused completely, I saw an equilateral triangle directly over me moving rapidly to the northwest, but more westerly. The triangle had 3 dimly-lit lights near the points of the triangle. I did not notice the color of the craft; however, my daughter thought it was black. She also asserted that the points on the triangle were rounded as opposed to sharp. The experience was only 3-5 seconds in length before the craft was out of sight, so each of our br! ains could only process a limited amount of information.The craft made no noise that we could hear. Because I do not know the size of the craft, it is difficult for me to assess the height and velocity. If it was the length of a mid-sized commercial jet liner, then I would guess that this craft was about 1000 feet about us and moving perfectly straight at 150-200 mph. This Power Point created image below is the best representation of what I and my daughter witnessed.((NUFORC Note: Witness provides no contact information. PD))
