    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

    @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

    @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.

    @Rick Lobrecht: Not too sure, but I remember back in the day of NetZero actually being free, they'd have a banner ad that was "always on top" that was it's own window (not the browser). So you could force users to download a small executable to use the WiFi (not to connect, but to actually reach out to the internet). You have to launch the file, which would then take up ad space on your desktop.

    I have no idea if this is even close to what they'd try (I'd actually bet not), but it's plausible.

    @jamjen: I can't remember what airport I was at, but they had an ad-supported wifi service where you had to watch an ad in your browser to get 15 minutes of connectivity. Getting on the network was open, just the browsing part was restricted until you watched the ad (or paid a little $ to get ad-free internet).

    I'd still like to pay to avoid ads. I'd get enough ads on the pages I visit (unless Adblock stops em dead), so I don't want ads popping up every now and then from the actual WiFi service itself. It may sting for some, but in my case, after paying $300+ for a flight to wherever, $30+ for the cab ride to the airport and other varied costs for drinks and food I get at either the terminal, mid-flight or both, what's another $10+ for access for a couple of hours.

    I have absolutely no problems with anything ad-supported. I don't expect anything for free, and it's a good compromise on a paying service.

    Who knows, I might actually buy something from SkyMall instead of thinking about it on the plane then forgetting all about it once I leave.
