Is There a Dynamite Shack?

Officer Zamora saw the object rise straight up from the ground slowly, but it didn't go very high. The flame coming from underneath it was blue with some orange at the bottom like he'd seen before. It wasn't making any smoke, though it was kicking up some dust on the ground. When the roar stopped, I heard a sharp tone whine from a high tone to a low tone. There was complete silence about the object.
