I was sitting in the passenger's side of the car, and i saw a dark triangular shape in the sky, and then drift in the clouds.I used to go to school at the alternative school in Moscow, though i live in another town. At the time the school got out at around 5-6:00 pm. I don't know the name of the road we were on, but it was down the road only a little ways from the alternitive school, and we were going to head west. We were sitting in traffic for a long time. It was sort of a windy cloudy day which is rather typical in Moscow. My friend was driving the car and i was in the passengers seat. We sat there for quite some time and i began looking up into the white sky and suddenly i saw something that was pretty strange. I didn't say anything for a moment and i did not take my eyes off of what is saw that day. In the sky was a dark colored triangular aircraft of some kind. It was perfectly triangular and was obviously not something natural. I wouldn't say it was black; more of a metallic dark grey. I was comepletely amazed at what i saw, and for the most part i wanted to be practical and believe it had an obvious explaination. It seemed to have been standing in place but suddenly it started moving. It was moving steadily fast. I moved fast enough that it was leaving sight rather quickly, but it wasn't leaving at lightning speed. It was a super cloudy day that day, and it was probably strange that we even saw it at all considering how overcast it was. I watched it go into the clouds and i kept looking out for it, but i simply didn't see it at all. My friend then spoke up and told me that she had just seen something really weird. She hadn't known that i had seen it too. And my i told her that i had seen it and we talked about it for the ride home. I kept looking for it all the way home, but i didn't see anything strange. I decided to believe it was nothing, and when i told adults, they sort of looked at me as though i didn't know what i was talking about, since i was only sixteen at the time. I gave up trying to get anyone to believe me and soon i quit thinking about it, though i never forgot it. A couple nights ago something sparked my memory and so i decided to look it up on the internet and i did some research. I didn't even know that triangular shaped UFO's are reported but i found out that they are. And i looked at the description and sure enough, the descriptions had an uncanny resemblance to what i saw. So, i looked into it further. I typed in something about triangular ufo's seen in Moscow Idaho. I didn't think i would get anything. I found a reporting on this website that took place on the same date someone else had reported a sighting. I also noticed that that it is not particularily common for Moscow to have reported UFO sightings on this website. But mainly, i was take away that it was on the same day. So my friend and i were not the only ones to see it, and not only that, but they saw a triangle as well. It is all rather eerie and too ironic to be an accident.
