I live 120 miles from Dallas and heard the noise clearly. Couldn't figure out what it was. Now we know. Very, very bad news.

I would have thought that 200,000 feet up would be so hoigh and the air so thin or non-existant, that we wouldn't hear anything. An explosion in space isn't heard by anyone if there's no air to carry to sound. Guess I'm wrong.
