        <description><![CDATA[We know it couldn't take off without some form of external fuel tanks so the video might have accidentally omitted a few things.  We understand flying bodies well enough to know this can work.  Now I'd just like someone to explain how they'll solve the challenges we had with our previous shuttle.  The public has become much more educated about this topic so now we want more specifics about how this thing could/would really work, not just cute little videos.]]></description>

        <description><![CDATA[In addition to DreamChaser, SpaceX has its Dragon capsule which, in addition to carrying cargo, could also be used to carry astronauts to ISS. The first Dragon was already launched aboard a SpaceX Dragon 9, successfully orbitted the globe, and successfully re-entered for splashdown and recovery.I very much hope the DreamChaser sees the top of an Atlas 5, and that SpaceDev gets its chance to fly astronaughts to ISS. Competition would be good for the industry.And as a reply to PSFTGURU, the HL-20 was designed to fly atop of the Saturn-V. The Dream Chaser by SpaceDev has always been seen as flying on top pf the Atlas 5.]]></description>

        <description><![CDATA[As far as meeting that 50-100 flights per orbital, it seems to me that in addition to supplying the ISS and space tourism, another logical opportunity would be short hyper-sonic point-to-point flights -- when your package absolutely needs to get there in 90 minutes. Just slap a FedEx logo on the side of the 'Dream Chaser'.  Of course there'd need to be either a launch site at each landing site, or a large carrier plane to take the 'Dream Chaser' back to its launch site. Similar to how the Space Shuttle is brought back to FL when it lands elsewhere, so that wouldn't be new technology.]]></description>

        <description><![CDATA[The demo cartoon is somewhat inaccurate. The current proposal calls for mounting the vehicle on the tip of a Saturn 5 rocket, the same rocket used to launch Apollo missions to the moon. Unfortunately, as terrific as that technology was, all of the equipment used to build Saturn 5 rockets was deliberately destroyed, essentially burning the bridge behind us, thus leaving us with the shuttle and it's current booster technology with its inherent risks as our only choice. I am sure that we can still build something large enough and stick it in a silo below ground level so we can easily mount anything on top we wish, perhaps starting with whoever destroyed our original fabrication tech. Or we can always buy stuff from the Russians. They never got rid of their old tech.]]></description>

        <description><![CDATA[From the video it seems implausible that it could store sufficient fuel to launch itself and carry a payload. I am not a rocket scientist, but I can't see how the fundamental physics of rocketry would allow enough power to launch the rocket into orbit without the machine as shown here being mostly fuel tanks. If jet fighters can fly in the stratosphere, isn't there a way to get space ships to launch using rockets or combo rocket/jet propulsion from the back of a large aircraft like a cargo plane?]]></description>
