My husband and I had just finished eating at a restaurant in Beaumont, Texas. It was about 10:00 PM, Central time. On the way out to the car, in the parking lot, I looked up and saw what I thought was an airplane. I kept watching it, and I realized that it didn't have the same type of lights as an airplane does. The lights were white, unlike airplane lights that are green, red, and white, and they were flashing in sequence. There was no noise such as you hear when a jet flies overhead. The object was silent or nearly silent.The object appeared to be triangular, but it was very hard to tell, since it was dark outside at the time. I didn't see any real outline of the object, again probably because it was so dark. It took a straight path over my head and over the restaurant.I took a video (I take my camera everywhere), but it was extremely difficult to keep the camera stable without a tripod. I'm always aggravated with UFO videos that are taken by a camera operator with a shaky hand, but now I realize just how hard it is to keep a moving object in the shot while also trying to watch it yourself.I was very excited, because I'd never seen anything like this before. Eventually the object just flew too far to keep track of. I still don't know what it was, but I'd certainly like to. It would be fantastic if someone has the proper equipment to stabilize this clip and/or do some sort of analysis. As it is, you can't tell much at all. Also, I'm sorry for the language at the end.
