My true UFO story (I was going to spoil it, but now people will have to read to the end...)
It was in 2008 (because I was living in my then new and since lost rented house).
I was taking the trash out, it was a clear night (no clouds at all) when I spotted something in the sky that was very weird which didn't look like any of the stars or planes visible in the distance.
It looked like a star that was shaped like a triangle (reminded me of the pointer on a computer screen, but without the little "tail"). I knew it wasn't a star by the size relative to the other little dots of light, its shape and its brightness.
For a moment I considered on-coming plane lights, but it was almost directly overhead and didn't move or change. It also had a glowing halo around it which I thought could be some kind of light effect diffusing through clouds, but there were no clouds.
Then scary things started to go through my mind since I couldn't identify this thing: a supernova - the image of which was just now reaching Earth, some kind of missile or nuclear weapon that was detonating, but whose effects hadn't reached the ground yet, an alien space craft, etc.
I ran inside to get my binoculars and when I got back outside the light in the center of the halo was now gone, but the halo remained for several minutes.
The next day at work I began typing on the computer about my sighting (probably on an eBay discussion board).
Soon I found out I wasn't the only one who saw this - the sighting was being reported by many people along the North Eastern seaboard since it seemed to defy anything normally seen in the night sky.
Finally, someone linked an article about the phenomenon - turned out it was a NASA rocket being tested that was launched from a base in Virginia and was visible on such a clear night by several states north of VA.
So my true UFO story turned into a true IFO story!
