We'll be here when you get back from doing the testing. Of course that would only establish that some of the dust came from the WTC (assuming there is any human DNA material in said dust). It would not establish the use of an energy weapon nor would it cast doubt upon the observed facts of the planes hitting the building.
DNA would do nothing to solve one of the numerous obvious problems with you idea which is that the dust certainly contains material that was not in the WTC (ie other random bits of stuff from around New York).
If you were somehow to isolate your sample so you only had material from the WTC (which frankly, I have no idea how you'd go about doing that) then you still left with two planes hitting the building and no energy weapon.
I know you've said the planes should have bounced off but that's nothing to be taken seriously. I suggest you watch "Nova Science Now", the special on going to Mars and you can see how less dense objects penetrate steel plates. The think you said makes planes penetrating the WTC is exactly the same thing that's a serious threat to spacecraft. Watching the bit about how NASA wants to protect the spacecraft will clear up your error on this point.
The energy weapon ain't my gig. Judy Wood says that stuff. I don't
"believe" it at all. It's just the best theory out there. Knock it down,
if you wish, and I will not care a bit.
My work does matter to me, and the issue of contamination has been
brought up many times, but there hasn't been a decent response to
my discussion about contamination. It's been a one-sided conversation.
Someone from JREF will say, "Your dust is contaminated." I respond with
a thoughtful discussion of the possible sources of contamination, and
then....crickets. Later on, someone else will mention that my dust is
contaminated, when they don't actually know that it is contaminated
(because they haven't tested for contamination) and don't really have
a good idea of what contamination is and how to conduct science
in the face of contamination. If a sample is contaminated, or suspected
to be contaminated, you don't just throw up your hands and say
that nothing can be done about it. Because something can be done about
contamination. It's not a strange concept, dealing with contamination.
It's not scary, nor does it invalidate things on a global scale.
The WTC dust might be contaminated with bacteria, but not more than
any other sample. If you think my WTC dust samples are contaminated
with cigarette butts, they aren't, but even if they were, big deal.
As long as I didn't come to a silly conclusion as a result, like that the
WTC was destroyed by a cigarette fire.
What's a cigarette going to do, anyway? Shatter steel into fragments?
I don't think so!
The reason I was able to isolate pure WTC dust is because there was
a lot of it in rather heavy chunks. The big chunks are still intact, never
having been investigated. So at least the stuff on the inside of the
chunks is pure WTC dust. If you think this stuff was sifting around like
sand, it wasn't. It had plopped down and stayed there for years,
protected from rain by a concrete overhang.
Some objects might penetrate steel plates. An airplane might even
penetrate a steel plate, if it wasn't too thick of a plate. But an
airplane couldn't have crashed into the south wall of WTC 2 without
at least SOME debris bouncing off the south wall of WTC 2 at the
moment of impact, and before the subsequent explosion, which was
real.
