What was it? Just a few minutes ago, I heard a short, fairly loud burst from up above. This was the third or fourth time I'd heard it in my neighborhood, which is a residential area.
Some people often say it's a sonic boom, but what exactly causes it? There are no ultrasonic jet planes in the area.
