REFERENCE THE FOLLOWING REPORTS: 17056,17327,17431,17438...I have several minutes of video of a very large craft flying enormous circles around my town. Everytime I go to take video of this object I think its some sort of airplane. But once in a while it will stop in the distance and many other lights will appear around it.The size and shape are difficult to determine but aside from the very first sighting I can hear this object. It sounds like a low roaring jet engine. There are usually 3 white lights in a triangle formation that are constantly lit, although at times there are only two. There is always a flashing red and a flashing white light.I have no idea what this is and am very conflicted as to what I am seeing. If this is an airplane what is it doing flying circles around my town, and what are all the light anomalies that I am seeing?I will have video uploaded before the weekend is over but I have video from the 10th to the 13th of this object.This craft is accompanied by flashes of light in the sky. I have video record from the 10th of bright flashes of light coming from the direction of the Ursa Major constellation.I need someone to review and enhance my video as soon as possible.
