		<description>Well if this is being released to the public as an experimental plane..... then what do we have that is classified better than this currently used?  In the 80&#039;s civis were about 10 years behind the technology curve, makes one wonder.</description>

		<description>I don&#039;t mean to tell the CIA their business, but a biofuel jet?  Please tell me there is something I don&#039;t know about the feasibility of using biological plants to power planes in just the simple terms of the acreage required to literally grow sustainable biofuel.   I thought we realized years ago that there just isn&#039;t enough fertile land to seriously develop biofuel as a means of energy.  I would urge DARPA to look at Hydrogen, since the planet is mostly water.  I realize this sounds like naivette and I suppose some of the high pressure and cooling requirements are an issue for hydrogen as well as (if i recall without looking it up) the corrosive aspects of hydrogen on storage containers... well maybe they&#039;re right after all.  Probably hard to keep Hydrogen cool during reentry for example or under extreme pressure without risk of explosion... especially when its likely carrying an explosive payload... Nevermind!</description>

		<description>Interesting that this thing flies at 13,000 mph.. That&#039;s half way around the world in one hour...

That&#039;s FAST! Doesn&#039;t leave much time to raise a defense but then, at that speed, what else besides a laser will be able to hit it and then only if something can accurately track it.  Wonder what the radar signature on this thing is?

So, speed not being an issue, that only leaves angle of desent to limit the striking range. However, if the rocket system can pretty well put this thing close to your target and the vehicle is used only to fine tune the aim, the angle of desent as a hinderance is negated...

Fearsome weapon delivery system indeed.</description>

		<description>FALCON	Force Application and Launch from the Continental United States

Look this and affiliated stuff up on globalsecurity.org and you&#039;ll see this is the &quot;final draft&quot; of the vehicle, which appears to be a high speed, high impact delivery method for a new generation of ground penetrating warheads, i.e. for use on Iranian bunkers. The full Minotaur IV (NOT the lite version) launch vehicle IS the method by which they will deliver this bad boy into a suborbital glide path to the target. The Kwaljaliin Atoll test range is where they test OPERATIONAL missiles. Don&#039;t buy that the test failed. 2010 was the target date to have this thing READY.</description>
