1987-07-22 - Seattle, WA - Triangle

Saw a triangular light formation on an aerial object with a light pulsing in the middle pass directly overhead on the Puget Sound

The sighting took place in Washington state on a state ferry going from Vashon Island to Fauntleroy in West Seattle. THe sighting took place at about 10:15PM on Thursday, July 8th. About 30 minutes before the sighting, waiting in line in the car for the ferry, I noticed a helicopter moving in from the NE to the SE. I saw it and then it moved behind us and I could hear it for some time. A little bit later I was on the ferry in the car, which was parked at the very front of the ferry. I saw one helicopter who had 5 or so uncolored lights on. I also saw another object, that I could not discern as a helicopter or plane. It was too far away for me to tell its shape, but I could tell it was pointed. I thought it might be a small airplane. The unidentified object was directly in front of the ferry, and the helicopter was a ways to the left, moving to circle the area. The helicopter and unidentified object appeared to be at about the same height, and around the same speed, though the helicopter was farther away (I am terrible at estimating distances and altitude and speed.) The helicopter's lights, after a few seconds, changed to one uncolored light and one red/blue light (it appeared to be two lights cloase to each other, but I am nto sure) that alternated in blinking between uncolored and red/blue. This was the lighting all helicopters I saw from that point on were using. The unidentified object remained the same in terms of lighting. I looked at the object closely, as it passed directly over the ferry. I saw that the lights were all uncolored, shaped in an equilateral triangle, with one light in the center appearing to pulsate. I saw this from directly under the object as it passed over the ferry. Then the object mobed behind us and the ferry itself obstructed my ability to see it. The helicopter also moved out of sight as it moved to the left of the ferry where I was unable to see it. However, a few minutes later one helicopter came over the hill directly in front of me, and another came in! from the right where it had been invisible to me before due to the ferry obstructing my vision. I estimate that in all there were 3 or 4, possibly even 5 helicopters that appeared to be circling the area around Vashon Island. The craft I saw did not exhibit physically remarkable flight characteristics, except possibly for air-speed which I am not capable of effectively judging and so have no idea. The craft simply moved in a straight line and maintained the same speed and altitude. Like I said I guess it was traveling a little faster than the helicopters in the area, but it is hard for me to tell. Once I got off the ferry I saw another helicopter which was likely one of the ones I had seen earlier coming around in the circle. As surprising as it may sound I did not attempt to look back across the water at the object and choppers after I got off the ferry. I am not certain why.
