I was standing on the back porch, smoking a cigarette at 11 pm Friday night when I saw what looked like an airplane over our airport to the East. I was about to walk back inside when it reacted to fireworks that ii heard coming from that direction. It went from completely still at 100-110 degrees from my position to about 50 degrees from my position in 1-2 seconds and came back to a complete stop. It stayed at the same altitude, which was just above the rooftop of the house behind me but looked to be maybe half a mile away from my location. It moved back and forth (left amd right) as I heard and could barely see more fireworks being popped. A big firework was popped and it immediately shot from being just above the rooftops to about 5000 feet within 1-2 seconds and came back to a complete stop. It hover there for at 5000 ft for a couple of minutes without moving at all and then desended back to being above the roof tops until it desended below where I could see and never came back up. I have never seen anything like it before.
