At 1:30AM I came out the house to the backyard to have a cigarette. It was a clear and beautiful night. The stars were out, and I started star gazing. When all of the sudden I saw a light formation in the shape of a triangle fly from north to south. The craft/lights made no sound whatsoever, after 25 seconds or so, the craft disappeared. There were no planes, or helicopters in the area. Managua, Nicaragua, where I'm located, has very limited flight traffic after 10PM. The only plane that lands after midnight is a Spirit Airlines flight that comes form Ft. Lauderdale, FL. And I'm very far from the airport. Therefore, it could not have been the airplane landing.
