If shit goes horribly wrong, two people will be alive who previously might have been killed, so I can see why it was made an option, and why Scaled is taking it.
What does his age have to do with it? IIRC, SS1 never hits more than 3G's at any point during it's flight path. This is comparable to the Shuttle, which travels 24,000 kmph (mach 18). And John Glenn went into space not too long ago on a Shuttle at age 78 (IIRC).
I'm not sold on the two-stage model for commercials flights however. It would render the craft ineffectual for many overseas routes due to lack of carrier aircraft. Rutan has to work out how to get to a single-stage vehicle (even if it requires mid-air-refueling). You can always contract to the USAF for air-tankers. Otherwise this exercise will never be more than a NY-LA, NY-TOK, NY-LON or tourist endeavour.:-(
Like many people forget, the Apollo capsules were not the first of their kind; they built on the ingenuity and practical experience of the Gemini and Mercury capsules that came before them.
Expecting a Rev 1 Space Shuttle (all-up, no scaled demonstator, unlike the X33 and X38) to achieve all the lofty goals set for it while being hamstrung with budget cuts was the height of 1970's stupidity.
I do believe that sabotage, sudden volcanic eruption, or mountains collapsing are not factored into the lifespan of containment vessels, since no structure we've yet to create could withstand any of the above.
I do believe it means normal weathering processes, erosion, wind, normal expansion/contraction stress effects. Hell, the pyramids and Stonehenge have been standing for 2-3000 years. Barring significant geological forces (or human action), there's no reason they couldn't stand another 3-10,000.
And there you are wrong. Itanium *WAS* designed as a general purpose CPU. And which Merced sucked royally, life got better in subsequent versions when Intel made improvements in the design. No, Itanium has failed because it cannot do the 32bit transition as well as every other processor in the past has done. MIPS R3000-R4000. Alpha 32-64 with OSF/Digital Unix/Tru64. Sun. AMD. Everyone but Intel figured it out. You cannot make the move to 64bits in general purpose computing if you do not make the 32bit software run fast.
Intel is not in the business of making special purpose CPUs. That's something Cray and Sequent (IIRC) wer famous for, and look where it got them?
Intel makes general purpose CPUs and is very good at it. i960 (you may argue this:-D) , Pentium, PIII, Pentium-M. Itanium was a bad idea, and their repositioning it as an HPC processor proves it. It will forever be marginalized. I expect it will have a shorter lifespan than the Alpha will.
Wrong, the fact of the matter is that VLIW (EPIC) sucks ass for general purpose computing, and Intel was counting on a fundamentally exponential improvement in compiler technology to make it work. When the universe finally figured out that dynamic scheduling and execution in hardware is where you're best off spending your time and money, it was too late to kill the Itanic beast. The problem in multiprocessing environments involves loop-unrolling and reducing memory accesses: you cannot do this safely if your running in a threaded or SMP environment, so compiler improvements are only going to bring you so much.
And Alpha was *THE* 64 bit king. SGI only had a toe-up in the video world because of their top-notch video processing hardware, something that companies like Accelgraphics and Integraph were attempting to remedy on the PCI based alpha boxes (Those designed to run NT as well as VMS). Sun continued to dominate simply because Solaris didn't suck as bad as Digital Unix/Tru64. HP was a complete non-starter performance-wise, hence their bet on Itanic/Intel. The fact that history would literally dump the EV6/EV7 architecture into their hands is ironic. And sad.
All urban legends. Check snopes.com. The boosters are made in Louisiana, and shipped by barge to Florida. No trains at all.
And the implicit stupidity of putting the SSME's in the Shuttle when there was no provision for engine restart, especially since that great fuel tank was already falling into the ocean. Yeah, the Soviets did it better in that regard.
As to tile technology, well that has matured some, but the fragility of the entire system is keeping NASA from any major overhauls in that regard. Had the Soviets actually continued with the program, they might just have built a flyback booster, aka, what the STS was supposed to be.
Considering that the U.S. would have known that Buran was flying, in order to prevent WW3, NORAD almost certainly had opportunity to debunk the flight of Buran with orbital tracking data. At the height of the Cold War, you can be certain that any U.S. proof of failure of the Energiya-Buran to achieve orbit would have been leaked by the Administration if the Soviets tried to play of a technological coup and failed...
The way I understand it is that all the F14's Iran has were subtly disabled when the Boeing contractors were forced to leave by having critical parts of the fire control systems removed.
Legislation? Hell no. They just need to be slapped with a defamement and or libel suit as quickly as you can pull a lawyer out of your ass. Do unto others and all that.
Or just fry them in the court of public opinion...
If it's not USB, then it's CD. If it's not CD, it's a download. If it's not a download, it's some zip file he got in the mail or it's some sales rep from Company XYZ who plugs his computer into your network to get at a document back at the home office...
You're focusing on the wrong problem. The problem is: how do I isolate users machines so they cannot infect the rest of the company, and yet still allow them to do useful work.
I have partial answers to this problem, but it really comes down to, how do we eliminate the social engineering aspect of trojans and viruses? I have no answer to that question. Education isn't working, perimeter defenses work partially (firewalls, AV scanners, etc).

Personally, if I could, I would. Your singular efforts to improve my own personal knowledge would guarantee it.

Alas, I am but one peon, one bad financial report away from unemployment.
Do not HUMP? Like some giant ogre is going to have his way sexually with an SRB motor segment?
Thanks for the pics, BTW.
If it makes you feel any better, it's running as a VM guest on a SuSE 8.2 host. :-)

An aerospace engineer is going to have an easier time retraining for ANY job than a steel factory floor worker, or a Java EJB wannabee.

I've never seen a 10-12' wide railcar. 11 segments @ 10', 12' in diameter, that's a big car.
I can't imagine there are a lot of tunnels between Utah and Florida via rail...

Perhaps because the 15 yo technology doesn't actually suck as bad as Itanic? But let's it right, COMPAQ killed Alpha before it became HPAQ.
Didn't know if you noticed, but wood is definitely less dense than steel and aluminum. :-) But your facts are correct.

So Tupolev is the equivalent of Microsoft to the Airplane industry?
And ECC and parity memory definitely uses more than 8 bits to represent a byte.
Thankfully, Chicken Little, planes do NOT fall out of the sky during a total air traffic control outage, but control regresses to pencil and paper.
Your plane *WILL* land. It may be at a different airport, and sooner or later than planned, but you will get on the ground in one piece.
