The BBC is running a story about 9/11 conspiracy theories:
On 11 September 2001, four passenger planes were hijacked by radical Islamist terrorists – almost 3,000 people were killed as the aircraft were flown into the World Trade Centre, the Pentagon and a Pennsylvania field. Just hours after the collapse of New York’s Twin Towers, a conspiracy theory surfaced online which persists more than 16 years later.
“Is it just me?” an internet user named David Rostcheck wrote, “or did anyone else recognise that it wasn’t the airplane impacts that blew up the World Trade Centre?
“I hope other people are actually catching this, but I haven’t seen anyone say it yet, so I guess I will. There’s no doubt that the planes hit the building and did a lot of damage. But look at the footage – those buildings were demolished,” he continued. “To demolish a building, you don’t need all that much explosive but it needs to be placed in the correct places… Someone had to have a lot of access to all of both towers and a lot of time to do this. This is pretty grim. The really dire part is – what were the planes for?”
Subsequent investigations made it clear that the tower structures were weakened by the inferno from the planes and felled by the weight of collapsing floors. However even now some people refuse to believe this version of events.
I watched the towers collapse on a television in the conference room of an engineering consultancy, surrounded by civil and structural engineers. None of us could believe what we saw, and many of us thought an airplane crashing into the towers couldn’t cause the towers to collapse as they did. A few months later some American TV station aired a program explaining exactly how they collapsed, someone recorded it, and we all packed into the same conference room to watch it. Everyone came away fully satisfied by the explanations given.
The video explained that the two towers fell in quite different ways. Their construction consisted of an inner steel core and an outer shell, held together by cross-braces made of light steel. Neither the inner core or outer shell could stand independently, so the cross bracing was essential. When the aircraft struck the impact knocked off a lot of the fire protection, and the subsequent fire weakened the cross bracing to the point the outer shell fell away, causing the entire tower to collapse. In one video clip you can actually see the core standing on its own for a fraction of a second before it too collapsed to the ground. The other tower fell differently. When the aircraft struck, the resulting fire weakened the supporting steel above the impact point so the entire (intact) tower section above slammed into the floor below, which gave way, and the process repeated through several floors bringing the entire structure crashing down. Although burning jet fuel is insufficient to melt steel, any increase in temperature beyond a certain point severely reduces its structural strength, and temperatures far exceeded that point.
There are many inexplicable elements to 9/11, but most have to do with the fact that this event was entirely without precedent. Nobody could possibly have predicted what would happen should two colossal skyscrapers come crashing down in sequence in the middle of a city, and the mechanisms it triggered in the immediate surroundings will never be properly understood. People say WTC 7 (or whatever) should not have collapsed in the way it did; well, nobody knows how a building is going to behave subject to forces of that nature, all we can do is look at the wreckage and try to figure it out. If the same thing was repeated half a dozen times we might get a better idea, but until then there will always be a lot of odd phenomena about 9/11 we can’t explain. This is what conspiracy theorists rely on when peddling their nonsense.
However, the point of my post is to highlight how much times have changed. When 9/11 occurred there was still some semblance of trust in the US government, and only demented conspiracy theorists believed it would be an inside job. Most people were even on board with the official explanation, which seemed to make sense to me. I certainly can’t see any reason not to believe the official version of events, at least those concerning the WTC and the Pentagon (the story of Flight 93 lends itself to some manipulation, not least because we don’t know for sure what the target was and how it was brought down). But public trust took a huge knock a year later when George W. Bush and co. started banging on about Iraq’s nuclear weapons and resorting to complete bullshit to make the case for war. Since then things have gone rapidly downhill: the Obama years saw the utter corruption of government agencies, flat-out lies concerning Benghazi and Fast and Furious, and since Trump’s election it’s been non-stop disinformation regarding Russia’s alleged interference in US politics. To cap it all, we had a gunman firing hundreds of rounds into a crowd in Las Vegas and after a brief period of feeding the public contemptible bullshit, law enforcement officials and politicians have decided they’re not going to tell anyone what happened, and the media aren’t in the slightest bit interested in finding out. The government’s reaction to this event was so remarkable that even normal, balanced people were convinced something was rotten about the whole thing. And we’re still waiting for answers, by the way.
So my point is that the 9/11 conspiracy theories are nonsense, but if 9/11 happened today the public would have every reason to think they were being told a pack of lies from the outset and they’d almost certainly be right. This collapse in public trust may prove almost as catastrophic as the collapse of the towers themselves.
