The paper clearly states it was designed for a plane going at 600 mph!!

But no one seems to be able to verify the study was actually done.

I am pretty sure I have heard statements by the designers that they did not anticipate impacts from planes as big as those planes.

Don't know and haven't paid much attention.
Also as I have read multiple times, I have heard from designer type people (you know people with PhDs and etc) repeatedly say they would have to of made those buildings into bunkers to make them 100% safe or ANY building. And nor is it cost effective to do such.
I am pretty sure I posted an article on one of these threads somewhere.
3. The buildings have been investigated and found to be safe in an assumed collision with a large jet airliner (Boeing 707-DC 8) traveling at 600 miles per hour. Analysis indicates that such collision would result in only local damage which could not cause collapse or substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact.

A telegraph from the architectural firm Richard Roth, partner at Emery Roth & Sons, was distributed to reporters on February 14, 1965. The telegraph was in response to claims by real estate baron and Lawrence Wien that the design of the Twin Towers was unsound.
["]THE STRUCTURAL ANALYSIS CARRIED OUT BY THE FIRM OF WORTHINGTON, SKILLING, HELLE & JACKSON IS THE MOST COMPLETE AND DETAILED OF ANY EVER MADE FOR ANY BUILDING STRUCTURE. THE PRELIMINARY CALCULATIONS ALONE COVER 1,200 PAGES AND INVOLVE OVER 100 DETAILED DRAWINGS.
...
4. BECAUSE OF ITS CONFIGURATION, WHICH IS ESSENTIALLY THAT OF A STEEL BEAM 209' DEEP, THE TOWERS ARE ACTUALLY FAR LESS DARING STRUCTURALLY THAN A CONVENTIONAL BUILDING SUCH AS THE EMPIRE STATE BUILDING WHERE THE SPINE OR BRACED AREA OF THE BUILDING IS FAR SMALLER IN RELATION TO ITS HEIGHT.
...
5. THE BUILDING AS DESIGNED IS SIXTEEN TIMES STIFFER THAN A CONVENTIONAL STRUCTURE. THE DESIGN CONCEPT IS SO SOUND THAT THE STRUCTURAL ENGINEER HAS BEEN ABLE TO BE ULTRA-CONSERVATIVE IN HIS DESIGN WITHOUT ADVERSELY AFFECTING THE ECONOMICS OF THE STRUCTURE. ...["]

Otherwords, it wasn't a fire that brought them down.
It wasn't a impact and the subsequent structural damage that brought them down either.
It was the double wammy of massive structure damage to that location and the jet fuel fueled fire that brought them down.
Neither one was suffiencent enough to bring them down just by themselves.
So your saying all the reports that state the building withstood the plane impacts and the fires were not hot enough or last long enough to cause the collapse are wrong or lied ?
You are also missing the point of the molten steel found in the basements and debris. We know the fires did not get hot enough to melt steel so something else had to cause the molten steel.
I also have posted steel buildings that had longer lasting fires and more structural damage then the WTC buildings and they did not collapse.

Nope, as I have said a few times now, I don't care what any report says.
I know what I know. And I see what I see.
Oh yea. The steel HAD to be molten before it got underground.
Couldn't have been melted by the fact it was then covered in a rather good insolator known as concrete with fires that were still burning heating the area up.
I haven't even bothered to look at the stupid thing.
...don't really plan to.
know what I know.
You know what, ignorance is bliss.
I think this is Wraoth pretty much saying he doesn't care about facts or data or anything that might change his mind. Because he isn't going to change his mind.
Insulators only hold in what heat is already there. The heat to melt the steel would already have to be there, so this isn't an explanation. Also I have never heard of friction melting steel to the point of flowing in open air, by any process. It strikes me as equivalent to trying to cut down a tree with a feather duster.
And if I come across to you as if there's no way you can correct me, then why get mad and put me on ignore?
Because I never said I knew everything, or anything even close. But if you can't rebut what I post then maybe you should consider that it's just because you're thinking from the wrong state of mind. And that's the entire point, what needs to be changed.
Either that or you can actually justify what I'm so off about. It seems like one or the other would be preferable to just putting me on ignore, but then again I don't know why exactly you post here.

Planes are tending to get bigger after all.
And those buildings were sorta old.
But eh.
