Black Triangle Fly-Over (Beaverton, OR)General Description of the Event: I was heading to my brother's house on the evening of Monday December 29th, 2008. At 6:05pm I was driving west on SW Taylors Ferry Rd. toward SW Washington Drive when I saw a strange set of lights fly overhead. These lights fit almost perfectly the description of a "Black Triangle", three white lights creating an equilateral triangle with a single red light in the middle of the other three. I could not make out any structures on the object.I slowed down and almost stopped my car as I watched it go behind the trees. I felt the urge to follow it but the speed was too great to match in a residential area and it was traveling in a direction I could not easily follow. In all I saw the object for about 10 seconds before it went out of view. I immediately drove to my brother's house a few blocks away and told him what happened. We went outside to look but did not see anything else.My Thought Process: At first I thought it was a low flying plane and thought nothing of it. Then as it flew overhead I thought, Hey, that looks like the general description of a black-triangle UFO, I should figure out what type of plane has those light patterns so I can debunk it, and began consciously trying to make out a conventional aircraft shape and patterns. As I failed to make out any familiar aircraft to go with this light pattern I began to realize I might be looking at something much more unique.Object Description: Four lights total; three white lights creating an equilateral triangle and a fourth red light at the center of all three. All the lights were steady with no flashes or pulsation, constant brightness. They did not move in relation to another. These lights were pointed down toward the ground, they were not pointed forward (as might be typical of an aircraft flying at night).The white lights appeared around the same color temperature and appearance of a typical halogen bulb. The red light appeared to be white light that had been filtered to red. Although vivid, it was not monochromatic (such as a red LED or laser light), it looked more like a red-filtered stage light. There were no strobe or marker lights.I cannot say for certain what the body/structure of the object looked like. It was dark with little ambient light surrounding it and none of the light emitted was self-illuminating. I would like to say I saw a black triangular structure but I cannot be certain. However, I was consciously trying to match a airplane shapes and patterns to what I saw and failed.Size was approximately 30 ft between each white light.Object Flight: 10-15 degrees West of North traveling with constant speed, direction, and elevation. Approximately double the tree height, so around 200 ft above ground. I would estimate speed between 60-80 MPH. It seemed to keep perfect alignment with the horizon with no visible rolling. Object was leading with an edge of the equilateral triangle created by the white lights, while the final "point" of the triangle was pointing in the direction opposite of travel.Other Notes: I was in the car with the music on and windows up. I did not hear anything unusual as it went overhead. I have a Camaro with T-Tops, so I could watch it fly overhead through the t-tops. There were no electrical or any other disturbances as it flew overhead.My Background: I am a 23 year old male. Graduate of Mechanical Engineering. Native of the Beaverton area in which the sighting occurred.
