I was outside at 9:30 pm and looked up from my patio and saw trianglar object hoving just over the top of my trees. Flat black in color about the size of 737. Made no sound, but did have three white lights on each tip. slowed down to a crawl and then kept heading SE from the NW. Never felt threatened nor fearful, just amazed.
Being a physician, I did some research it looked like a TR-34. That doesn’t surprise me since here in Omaha we have Stratcom at Offiut Air Force Base to the SE.
