Happened twice to me. Driving on a long, lonely stretch of New Mexico highway (between Springer and Clayton) at about 85 mph a fighter jet came from my right at a low altitude and flew right over the top of me. Went around and did it again. And then a third time. He was clearly using me as some kind of target for the exercise he was doing.
Second time I was fly fishing in the middle of 11-mile Canyon in Colorado with two of my buddies. Out of nowhere a monstrous "BOOM" shook us to our very core. Scared the crap out of all three of us. We were simply speechless. One my buddies saw the plane just before the boom. We figured it was an Air Force Academy pilot who got a little ambitious on the throttle and moved through the sound barrier. Not supposed to do that - but he did. And we still talk about how scared we were for about 5 seconds.
