Large Triangle shaped craft hovering over the cape fear river in Wilmington NCIt was a large triangle shaped air craft sitting still, hovering over the capefear river not far from the Memorial bridge. It looked to be about 30 stories in the air.. (not very good at measurments) We were able to make out the triangle shape, because it was some what iluminated. There was a green/blue light and a red light. It looked to be completley motionless. no spinning or anything. We were going south on high 17/74. we were driving so I do not know how long it was there. My Mom who was driving did not want to go back to check it out. No noise was heard.
