Deadly Infrasounds on 9/11?

[Inductor]

Fact or fiction. I am not here to say.
The problem is that everybody is afraid of talking and no science is strong enough to handle it. I can understand the reasons. Maybe it's against the rules of the moderators of diyAudio. We shall see...
Infrasonics can be interesting though if we think about the science behind the "Deadly Sounds" of Dr. Vladimir Gavreau and Gavreau's sound weapons or about Nikola Tesla and the Tesla's Earthquake Machine.
Please feel free to criticize.

If this is an audio discussion, fine. If it's political, you know the rules.

I think the large jets commandeered by a group of mass-murderers flying into the buildings might be a more likely hypothesis. What you mean by "no science is strong enough to handle it" is mystifying.

If you look at the videos of actual harmonic destruction such as the galloping Girtie bridge you can see how it works and why such mechanisms are obvious. It takes a while to build enough energy (5 minutes plus in the video) and the motion continues to grow until failure.

Not the case here.

OK I'll talk.

Infrasound that powerful would have been felt by thousands of people, other buildings would also have been affected due to the wavelength.

People would have been seeing blobs, if the frequency was near 18.9 Hz.

Conspiracy solved.

I found your weapon of mass destruction.

Turns out Alkiada is using riced-out minivans.
