My office is right across the street from the north end of runway 15 at KBUR. I was sitting here, and heard what sounded like a gunshot, followed by a screeching sound. I went to the window, and heard it again. I noticed a couple of people near the end of the runway standing next to a truck with the airport logo, so I went out front to get a better look, and saw that it looked like one of them had some kind of gun that he pointed in the air and shot for a 3rd time.
Does anyone have an idea of what they were doing? Is this some way of checking winds, or the radar or something?
Very strange...
