Chicky chicky boom shirt. When you crack a bullwhip the noise you hear happens when the whip breaks the sound barrier. When I was a kid we heard sonic booms several times a week until they were banned over metropolitan areas. You could hear it coming and then it would hit. Houses would shake and the windows would rattle and sometimes break. I love the Blue Angels used to fly over every single day synchronized when I lived Boise they’d fly in from Mountain Home Air Force Base, synchronized so awesome! Ive witnessed it aboard us navy ship, the USS Milwaukee oiler refueler.
