    The white "cloud" you see around isn't the sonic boom. The vapor cone has nothing to do with breaking the sound barrier, just a drop in air pressure at the nose of the rocket.

    However, just like Carl Sagan said at the end of one of his books; "But I could be wrong." #aresix

    "Be amazed at the sheer beauty of the mighty rocket as it breaks the sound barrier... "
    It is amazing, but not necessarily an indication of breaking the sound barrier. The shock cone in this picture is actually a Prandtl-Glauert singularity which can occur below the threshold of sound. The rocket is going fast enough, with enough moisture in the air around it, to cause a compression-rarefaction-recovery... curve. The negative pressure shock during recovery results in condensation. This phenomenon is not limited to transonic jets and rockets. Even a bullwhip can cause a P-G singularity. Mmmm paste... #aresix

    @John Hendow: The rocket went Mach 4. I believe that's enough to break the sound barrier regardless of what the picture indicated. #aresix

    @ripfire: The rocket reached a top speed of 4.7M. This was slightly before MAX-Q (maximum dynamic pressure) and so does show the pressure wave build up from approaching the speed of sound, however it started dissipating before it reached it. #aresix

    So what's the difference between this rocket and the ones that they used in the 1970s or so? I'm sure there have been improvements, but it's hard for us civilians to appreciate or understand the technical details. #aresix

    @Hello Mister Walrus:

    This is based off of space shuttle tech if I remember right. The first stage boost is supposedly built from the current shuttle's fuel tank.

    I would like to know if this thing can make it to the moon as-is, or if they'll need additionaly boosters on top of that. #aresix

    @Hello Mister Walrus:
    It uses solid repellent and not conventional liquid fuel. Advantages are not likely to explode and can reuse the shell. Disadvantage you can't throttle up or down and once ignited you cant "shut" it off. #aresix

    @ripfire:
    Solid fuel only burns on the outside surface and as the surface layers burn off the lower layers start to burn and become the surface. So it IS much less likely to suffer a catastrophic explosion then volatile liquid propellants. #aresix

    So we shot a nose cone into the Atlantic. Stuff Alan Shepard in there, and it's 1961 all over again. Where's the 50 years of progress? #aresix

    @mwhite66: We lost the technology. We lost the tooling. We lost the pioneering spirit that drove people to literally shoot for the moon.

    The Shuttle was supposed to be a superior technology, and in some ways it really was, but from a versatility and cost standpoint it was a loss.

    Over 50 years people retire, people die, blueprints get lost, tribal knowledge disappears, and you literally have to re-invent the rocket to get back to where you were back then. Only, updated with all the latest/greatest innovative hardware. #aresix

    "OK, so it looks like a flying condom"

    So a review from Frucci is pending?

    Note: Yes, I know this is probably getting old but that review is permanently scarring my brain and with terms like "One Spectacular Big Bang", "sheer beauty of the mighty rocket ", "six minute flight was a success", and "the vehicle flew better than expected", I couldn't help myself.
