The collapsing towers created the same conditions you can demonstrate in your kitchen with iron oxide, aluminum, and heat created by impact. That's why all those things, in varying amounts, were there.

I'm sure you have heard of the word momentum. I won't trouble you with the scientific formulae related but lets just say if you knocked on someones door with your fist in the normal way, and then with the same fist, you took a Mohamed Ali swing at the same door you might just punch a hole right through it. Well if you take an airplane and run it into a building at 250 knots, you would do some damage obviously. But if you took the same airplane and hit the building at ~twice that speed you would do a lot more damage. The WTC buildings were within whats called a TRSA, which means they were close to an airport, but more importantly the speed within a TRSA is 250 knots. So when the WTC designers made their construction plans one of the parameter they used was to deal with an airliner impact at 250 kts. One of the designers I heard interviewd said to this day we couldn't build a tower that would withstand a 767 collision at double that speed. That's roughly the speeds the airliners hit the buildings. Apparently the terrorist hijackers weren't following FAA regulations.

I've explained that already. Now on to airspeeds.

Airspeeds?

Or you could just put a match to fine steel wool. Any progress on those airspeeds or does that frighten you?

I have already pointed out what the source of the microspheres at the WTC. And I see you continue to dance around the questions of aircraft speed and related design criteria, so I have to assume you will follow your narrow minded conspiracy theory ideas that have been put in your head forever. No sense wasting more of my time with trying to educate you.

I even showed you how you can make them at home. And if you try it there you can see how the amount of heat generated by a collapsing building as big as the WTC towers would explain the molten metal.

Do you ever plan to answer the question as to aircraft speed?

C'mon Wilber, surely you have heard of superthermite. It's manufactured on Alpha Centauri but only the US government has access to it.

Um, terrorist hijacked and then drove big planes at high speed into tall buildings not far below the top and then the top came down and pancaked the rest. Kind of a bad ass Batman theme perhaps.

All of this is explained by the actual science I have already forwarded you. Now, one way to demolish a tower is to blow up and weaken the structure some distance below the top of the structure and let the top part collapse and take out the remaining floors. It puts it all in a neat pile in a relatively small footprint and is much quicker than taking it apart piece by piece. So in the WTC case, the same process was used except they used fast airplanes laden with lots of fuel instead of explosives. Now, another question you have hidden from forever is how fast were those planes going when they hit and why did that exceed the design parameters built into the towers?

Have you bothered to study abortion laws in the US? BTW abortions are available in PEI. Try to keep up OK.

The reason it was shunned was because it became just how obviously it could be abused. How easy would it be for a bigoted neighbor to call in some bullshit like maybe the lady next door was wearing a face covering, which is one of the things Harper was trying to go after when he sought to create this nonsense.

So you continue to fail to answer direct questions. Carry on with your conspiracy notions.

It's technical stuff you are not familiar with so I understand it can be confusing. Here is something simpler though, how fast do you think those planes were going when they hit the towers compared to how fast an impact they were designed to withstand?

Sorry, what is it that has you confused, is it altimeters or thermite production.

The hoopla over the issue was that the Harper gov't wanted to create their so called "snitch line" with regard to barbaric cultural practices. How easily could that be abused!

So you don't know much about aviation but you seem to think you know about engineering design. In the case of the WTC collapses both of those professions come together. The towers were in fact designed to withstand impact by an aircraft. Do you have any idea any of the parameters of that design consideration?

Nope, section 2 of our Charter of Rights gives us free speech, we just limit here and there to protect people from such things as hate speech. Just as we have rights to have firearms but we limit that a bit too so we don't have people blowing away vast numbers of high school students away on a regular basis. I wonder if hate speech and gun violence are somehow linked, what do ya think there?

Oh so when a little inconvenient truth comes out it's "off topic" Riiiight.

One of the links you provided a while ago led to a discussion by some conspiracy theorist that flight 77 would have had to descend in the last few seconds at some crazy rate of 21,000 fpm or so, but then to prove that there was an image of flight data that showed an altimeter HEIGHT of 180' and then went on to try and prove the a/c was actually 300 ' higher because of altimeter setting differences. But what is clearly shown in the image presented is a radar altimeter, not a sensitive altimeter. The former does not work off barometric pressure but rather radar signals bounced off the ground below and hence it records height, not altitude. If impact was in fact 2 seconds after this image then the aircraft would have had to descend at 90'/sec., which amounts to 5400'/minute, not 21,000 and easily done in a 757.

Have you yet figured out the difference between those altimeters. I can clue you in if need be.

Oh don't worry, I enjoy flying but not into buildings, even if I know I could knock them down. The chief pilot frowns on that kind of activity.

Yes you are right about that.
