And FYI the idea literally was written into a Tom Clancy novel years before (although IIRC it was Japan that attacked) so the terrorists did not even need to be creative
I'm glad I'm not the only one who remembers that.
I remember as soon as I heard the news about planes crashing into the World Trade Center and Pentagon my first thought was, "wow, it's just like in Debt of Honor".
Even back then I thought the media narrative was hysterical and insane.
As you said, the idea of using planes to attack buildings wasn't exactly obscure - Tom Clancy was among the most popular authors of the 90s, and the world trade center been a target of terrorists attacks already.
People were acting like their entire world view had been shattered by the fact that terrorists finally succeded in destroying the building they'd been trying to destroy for a decade. Were they just not paying attention to the first two attempts?
And what does any of that have to do with the physical (civil and thermodynamics engineering) science of it all?
Those who accuse me of writing posts devoid of information then don't address posts like this which are disinformational.
How did the fires under the rubble as seen from IR satellite imagery burn so intensely hot and long without oxygen? What was the fuel?
