Strange lighted object in the sky

I noticed something odd, at first dismissed the idea and thought of another airplane flying by. However as I continued to star gaze and enjoy the moon so close, the lighted aircraft began to move in unusual maneuvers. As if a kid flying a kite the movement was similar, that’s what made me think something odd and strange. It briefly disappeared only to reappear close enough to see what resumed to be any other aircraft with red and white blinking lights flying a straight pattern. There was almost no sound made when it flew by, unlike the jets that fly over daily. My dog barked most of the night, he has never done that on any other night.
