Massive triangle craft flying south, south west aprox 1:30am , aprox 400 ft above my house. Size aprox 400 ft point to point. Speed aprox 50 mph over my trees, blocked out the moon and stars for 3 to 4 sec. Looked like it was 10 to 15 stories high or thick. No bottom lights or sound but could see the different levels dimly Lipton the sides. Was incredible and almost unbelievable. Never said anything about it until now.
