I was sitting on the back stairs of the house shortly after 1am talking on the phone with a friend. all of a sudden my phone went completely dead. I had just charged it, but it would not turn back on. suddenly, the sky grew bright behind the house, I looked up and two round looking objects shot overhead no more then 500ft above me. They continued straight, then shot off at 90 degree angles from each other. They then began to execute several sharp maneuvers that as an amateur pilot I know aren't possible to be done with conventional aircraft. They glowed and pulsed with a blue green and orangish yellow colors, sometimes randomly other times staying solid. the even lasted maybe 45seconds to a minute before both suddenly shot straight up and disappeared.
