I was visiting a family member and we were sitting on her back porch talking. I was facing west, she, east. Mid-afternoon, no clouds etc, no weather conditions other than Sunny.While visiting with her, I noticed movement up in the sky and just watched as this silver triangle shaped craft with a dark (black) triangle in the middle, about a quarter or a third full size in the middle of it, just watched as it traversed from North to South in the matter of about a minute, maybe less. It appeared to be very high up and compared to watching a jet pass in the sky, this object must have been moving extremely fast to cover the range of my view of the sky so quickly.I didn't want to interrupt while she was talking and once it'd passed, there wasn't much use in mentioning it to her I figured. I don't recall what the conversation was about but, it didn't seem worthwhile to mention it to her and cause any interruption.That's pretty much it. I only recently mentioned it to a friend a few days ago who thought I ought to report it.From what I could see, it had none of the features that I keep seeing on Hangar 1 or other programs I watch regularly on TV. The silver color of it was not a shiny silver but what I'd describe as a matte finish. It had no windows, doors or any other visible marking from my vantage point.Other than seeing a triangle flying across the sky, there was just nothing of interest to it at all. It didn't change path, speed or direction.You can contact me if you have any questions. Sorry I waited so long to report this.
