I don't know whether this has been posted before or not, but yeah.
Who among you have witnessed a sonic boom? What does the plane look like? Is the wind-skirt-thing real, like the ones in cartoons? And what does it feel and sound like? Any personal opinions about supersonic aircraft are appreciated too.
What is the actual cause for the shiver you feel when you hear a particular piece of music or when you see something disturbing? We all know the feeling, that tingle that goes out the arms and down the legs. Is it an adrenal rush or what?
