White orbs off Duck, NC

We were standing on the beach, observing the stars and night sky.  Off to the East high in the sky, multiple white lights faded in the view, move at extreme speed circling each other, moving at sharp angles, left to right and back to left.  At one point, one white light split into two red orbs, that moved independently away from each other, then in sharp angles at a high rate of speed, then came back together into one white orb again.  A couple of them shot off to the north and out of sight in a second. Eventually, they all blinked out one by one and disappeared.
