    Missile Defense

Russian military leaders have expressed concern about US plans for a national missile defense system. Will defense technology be limited by possibilities for a strategic imbalance? Is this just SDI all over again?

On the air contact faces of the plane this is absolutely true (the air's relative kinetic energy means the effective temperature is high),

I donno' man. The air must speed up on the top of the wing to lift it. That's why the top has more of a curve etc.

But I'm on shakey ground since we are talking about supersonic speed which is a new ballgame.

They do say that the SR-71 used to drool fuel as it took off since the metal expanded so much from the tremendous heat that it had to be built loose. That it glowed red hot at speed.

Of course, it is preferable to shoot it down long before it gets to the atmosphere.

dirac - on the top of the wing, pressures are lower by a few percent -- it is nothing like a vacuum.

In any case, for lasar pulse times, atmospheric cooling isn't significant.

I repeat

the basic physics here is all unclassified. Why doesn't the military, or Lockheed Martin, or some other reputable source of engineering talent, get a real person, with a name and a face, in front of a video camera, with me or any of a number of other people who could do the job, with UMPIRES there so he couldn't lie ---- and establish, beyond any reasonable doubt at all, that this stuff isn't respectable engineering, but is a fraud instead.

So that the proceedings can be put on a video feed on the internet -- for everyone to see.

The U.S. Patent Office has people with sufficient competence and integrity to do the umpiring job, but the British Patent Office -- or people from their opposite number to our NIST - might be better.

Some Russians watching might make it even clearer.

It should be possible to set this out in public, so that anyone, at leisure, could get on the internet and look, believe their eyes, and check details.

guys, this is life and death. Some people might be reminded, if they took time to listen to a sermon, by a very able, mainstream clergyman, preaching to very comfortable, generally economically well off folks, mostly republicans.

to get to meat on nuclear stakes, skip the first 9:20.

But we are talking about the end of the world, if mistakes are made here, and we are anything but lucky.

And "mistakes" are being made.

Though I wonder if the word "mistake" is rather too kind.
