My window has a view to the air space of Newark airport in NJ. I always what the airplanes landing and taking off when I'm in my living room. On August 17th at 7:20pm, I was surprised when I saw initially 2 (I though were airplanes) objects fling close to each other. They were high enough in the sky not to affect the airport traffic, but I could see they were flying relatively close to each other, so I wonder what they were. I know airplanes don't fly together like that. I took my phone and zoomed to take a picture and what a surprise when I notice a 3rd object on my picture. They were in triangle formation, but the third one was kind of far.I watch them crossing the sky for about 5 min. They were shine like a star and reflective. I stared all the time I could trying to see something that could indicate they were airplanes, but as they move to another angle, I still seeing three bright objects like a star. I didn't see any wings.
