Comment How does it work? (Score 1) 77
So I'm asking because I'm clueless. I know that when exceeding Mach1 there'll be a "boom" sound called supersonic boom. But do these planes first climb to high altitude, head out to sea, before actually achieving Mach speed? If they do that, I don't see such a great impact on civilian lives below. Again, I'm clueless, and appreciate if anybody can help understand how this works.
