    Hey Joe,
         You will definitely be able to hear the sonic
    boom a few minutes after it passes directly overhead
    if that is where you will be watching from. I've
    watched it re-enter several times from Temple Texas at
    night - spectacular. And I heard *3* booms in short
    succession. I can explain two of them (the over and
    then under pressure wave) but not three (probably a
    bounce off some thermal layer way up. But I can't
    speak for daylight visibility. However, I have a
    question: Where do I get information on the re-entry
    path??? I can't seem to navigate the site to
    find the landing tracks (usually they show 3 of the
    paths for 3 different orbit opportunities).
