And even if they could somehow ensure it was 'commercial-sized jet proof' when it was built, it may not have been ~30 years later. Especially after some structural damage from the 1993 attack that was never properly fixed:

After the 1993 bombing, inspections found fireproofing to be deficient. The Port Authority was in the process of replacing it, but replacement had been completed on only 18 floors in 1 WTC, including all the floors affected by the aircraft impact and fires,[15] and on 13 floors in 2 WTC, although only three of these floors (77, 78, and 85) were directly affected by the aircraft impact.[16][note 2]

So both towers were bombed in 1993? Roll Eyes

hmmm not sure I'd be crowing about the illegitimacy of an engineering theory on the basis that it "only" has a "couple of hundred" engineers supporting it Grin

Must be millions of engineers out there Gandalf, was Osama a civil engineer?

There are engineers out there with questionable qualifications I suspect many of them are on the nutjobs website Gnads linked which has around 1000 members. I should add architects aren't engineers they contract all engineering work out to engineers.

We just have to look at the Mascot towers debacle to see we have people in Australia with questionable engineering qualifications.

Quote:

Mascot Towers' residents vote to pay $7 million in levies as repair bill blows out to $20 million

Unit owners in Sydney's evacuated Mascot Towers building have learnt the repair bill could blow out to $20 million as construction engineers zero in on what caused the complex to crack.

Engineers, who have been assessing the damage at Mascot Towers and believe they know what caused the building to crack also spoke at the meeting, which ran for more than four hours.
However, they did not make their report public.

https://www.abc.net.au/news/2019-08-23/mascot-towers-repair-bill-soars-to-20-mil...

Like those peddling the official WTC collapse theory?

Which btw has changed at least once. Roll Eyes

The WTC was really a crappy design done that way to make it cheap and quick to build.

Saw a great documentary very shortly after 9/11 explaining why they collapsed so easily. There were actually a lot of factors, but one of the main ones I remember was they skimped on the fire-proof cladding. From memory it was due for re-cladding at the time of the attack.

Still, you can't really blame the designers for not coming up with a "commercial-jet-ramming-induced-fireblaze" contingency.

I think you'll find they did.. & it has been discussed at length in this thread.

https://www.ae911truth.org/evidence/faqs/360-faq-2-were-the-twin-towers-designed...

At 16 min 50 seconds this video debunks all the bullshit from your nutjob website.

The outer columns can clearly be seen bucking inwards, if it was an explosive demolition would they buckle outwards and you would see the effects of any explosion.

The falling debris in freefall clearly outpaces the falling tower which debunks the bullshit about towers falling in freefall.

Must be millions of engineers on this planet, why does your website only have a couple of hundred engineers which would be less than 0.00001 % of all engineers?

The 9/11 conspiracy theory nutjobs have wasted the last 18 years believing any bullshit they find on the internet.
Grin

So you doubt the original design engineer stating it was designed to handle/withstand being hit by jet airplanes?

And you're also saying that 99.99% of "all engineers agree with the official explanations?

freefall? ... It didn't say anything about freefall .....

All I have ever said is it collapsed vertically - which it did - in relatively quick time - in it's own foot print........ which is also how controlled demolition occurs.

I don't swallow that the top 20 odd floors on one building & the top 12 on the other caused the whole lot to crumble into the ground.

The buildings did withstand being hit by the jet, they did not withstand the fires that raged on for an hour before they fell. ike I have said if they could have put the fires out the WTC might still be there despite impact damage from the planes.

There are millions of engineers out there, why does Sydney Uni and UNSW have papers out backing up what happened are they part of this nutjob conspiracy as well?

The website you linked mentions freefall do you disagree with what they wrote?

Gravity tends to make things fall vertically, gravity works perpendicular to the surface of the earth you're not very good at this are you.
If it landed in it's footprint why was debris spread out over 20 acres, another myth from the nutjobs that is easily busted

I have no doubt the falling tops of the WTC caused the whole thing to come down.It's what engineers call a dynamic load, civil engineers don't deal with dynamic loads they deal with static loads.

All the engineers I know laugh at the controlled demolition nutjobs, why would you waste time and money setting up explosives when they weren't needed?

Of course the nutjobs think Bush got onto the phone with his Saudi mates and said righto I have it all wired up ready to go send in the suicidal hijackers.
Grin

Because the buildings & their surrounds & foundations covered close to that area.

They didn't topple dipshyte .... otherwise it would have covered more that 20 acres.

They cleaned it up Gnads.

Prior to any clean up, immediately/shortly after. Roll Eyes

Two towers of 104 floors - 1776 feet or 541 mtrs of steel & concrete ...

turned virtually into a hole in the ground with some surrounding debris that doesn't go too high.

How high does it go? And where is this hole in the ground?

Do you have an alternative theory, or are you just chronically confused, like Ajax?

I posted photos maybe you should try opening your eyes?

You posted a photo of a massive pile of rubble with comparitively tiny cranes at the edge cleaning it up. You thought you saw a hole in the middle. You are deluded.

Do you have an alternative theory, or are you just chronically confused, like Ajax?

Yeah tiny cranes on the perimeter ... hadn't cleaned up squat because of the heat. Roll Eyes

You're the deluded one following the govt. arse covering.

World Trade Center 7 Report Puts 9/11 Conspiracy Theory to Rest
Conspiracy theorists have long claimed that explosives downed World Trade Center 7, north of the Twin Towers. The long-awaited report from the National Institute of Standards and Technology (NIST) conclusively rebuts those claims. Fire alone brought down the building, the report concludes, pointing to thermal expansion of key structural members as the culprit. The report also raises concerns that other large buildings might be more vulnerable to fire-induced structural failure than previously thought.

The Government could clear this up by releasing footage from the Pentagon and surrounding businesses that would confirm a jet airliner crashed into the building....Why wont they release the footage and why is there so many conflicting accounts of what happened....IMO it is the lack of information that is being kept from the public that helps fuel conspiracy theories???

If a 767 hit the pentagon where is all the debris....????

Just a few small items like the landing gear and the engines, the fuselage wings and tail, seats, a few dead bodies, clothes bags.

There was just a hole in the wall, looked like a missile had exploded imo.
