Black Triangle Sighting in Concord, North Carolina on June 11th 2015 – I saw a triangular shaped aircraft with pulsating lights over my house.

I came outside to take my dog to the bathroom and saw a triangle shaped aircraft with 3 white pulsating lights hovering then moving slowly NE then lights went off and the craft disappeared. I'm a former navy rescue so I know all about aircraft warning lights and I've never seen anything like that in the military.
