The south tower fell in 10 seconds—I’ve watched the tape in real time. You’ve seen reliable reports claiming durations� C’mon—look at the tape and time it yourself. If even a fraction of time..say half a second per floor resistance occured—it would’ve taken conservatively 40 seconds to fall. Don’t just argue—think and research.
Ummm, I did research. How else could I have known that the estimates for the fall were up to 15+ seconds? And what tape did you look at? Provide us a link to a copy of the video you used. From all the videos I’ve seen, there’s no way to know for sure exactly how long it took to fall. There were always buildings in the way, or dust and smoke, or the picture just wasn’t clear enough.
And once more, what alternative theory are you offering, if you say that it couldn’t have fallen that fast with all the floors in the way? Because knocking down the building with explosives would result in the exact same resistances that the building falling as a result of the fires, unless you used such massive amounts of explosives that you simply obliterate every floor (which clearly didn’t happen). Regardless of whether it fell due to the fires weakening the supporting structure so that it collapsed, or if it fell due to explosives simulating such a collapse, it would have fallen at the same speed. So the speed at which the building fell, whatever speed it may have been, was the speed at which it would collapse under its own weight. There isn’t another possibility that will fit.
WTC 7 could’ve been wired to implode in 8 hours while there were fires burning in the building and chaos all around
Why not? Maybe you should do a little research into what it takes to wire a building for perfect implosion and then you wouldn’t make such careless comments. Why don’t you ask someone at Controlled Demolition—they imploded the other trade center buildings in the ‘clean up’—I’ll bet you could find some info.
Buildings don’t fall nicely into their own footprint only after days of planning and dozens of hours of setting up charges. Sometimes it happens spontaneously. It can also be done intentionally, if you’re willing to skip all the careful exact calculations and the double- and triple-checking that goes into more leisurely controlled demolitions.
And finally that 1800 degrees farenheit was wrong. Actually that is a low figure
I actually misspoke here—it would’ve taken temperatures of 2000 degrees for over eight hours within an enclosed vessel in order to see any degree of warping—and according to the NIST report, even that wasn’t enough—they had to double the time and increase the temp—and by the way both the columns and the floor supports were tested—bolts rivets?, no—if this were the case—the columns would’ve been standing after the collapse—you see the columns were built as the core of the building and the floors were attached�either the floors pancaked down or the columns fell over—we both know the building didn’t fall over—and so you are left again with resistance of .08 seconds total.
Okay, now you’re switching things around. First, you said:
The maximum temperature of a flame in open air is 1800 degrees.
So you were talking about how hot a flame can get, and how that wasn’t hot enough to effect steel. Then you said that you’d made a mistake, and that it’s actually higher than 1800�F. And now you’ve done something else with that data, apparently saying that the original 1800�F you mentioned isn’t the temperature at which a flame burns, but rather that it’s the temperature at which the steel was tested. What are you talking about?
Also, you’re saying that after the bolts and rivets that hold the support columns together and in place break, that the columns would have remained in place? That makes no sense.
By the way: after checking around a bit, it looks like various types of steel will soften noticeably or turn brittle at temperatures ranging from just 500� to 800�C (932� to 1472�C) in only a matter of minutes, especially if they’re under a lot of strain. . .such as a rivet or bolt would be on a supporting column. And jet fuel fires can easily burn at temperatures from 2000� to 6000�C.
A ball would drop from the top in 9.2 seconds. The south tower fell in about ten seconds.
. . .the resistance was .08 seconds total.
. . .and so you are left again with resistance of .08 seconds total.
Funny how you’ve magically moved that decimal point around to make things look more unlikely. . .
