lights in North phoenix sky 2-28-17 at 7:45 pm

Well, on 2-28-17, at around 7:45, in the North Phoenix sky 2 orange objects appeared. Looked almost like a fire in the sky.  The first object appeared then traveled SE in direction.  Folliwed by a secind that just appeared from nowhere.  At one point they stopped and just stayed there illuminating the sky.  However these objects had no blinking lights like aircraft do. Also just to ket you know there was plenty of planes that were in the area.  Around the Deer Valley Airport to be specific.  Now I know other aircraft spotted these objects and I know for certain the tower had recieved radio contact from many of the planes.  In regards to what was in the sky they were seeing?  Clear as the night sky these objects vanished.  But not because they had gotton further away.  Vanished like looking at them very clear in the sky.  To dimming out and disappearing completely.
