Large, silent v shape, translucent but had luminescence flying and appeared twice

It was very large, much larger than commercial planes flying overhead. It came from the north and was flying south east. It was a chevron shape, almost translucent in that it matched the night sky. There were “lights” that looked almost like small luminescent reflectors than actual lights, about 20-30 that were in the shape of the craft. It had a haze around it that helped make out the shape. It was flying quicker than the commercial craft. Absolutely silent. Flew straight and then in a weird sideways pattern before continuing on its original path. It did not appear to be any sort of plane or small military craft that is publicly known. It returned about 15 min later, following the same path. Without the haze and glowing quality (they almost looked like the appearance of distant stars except they were all moving together in formation) we would have not seen the object.
