OK, this is a conspiracy theory (in the strict definition) that I am closely monitoring for further information.
I have a university degree in a related field of science on this topic
In history, there has never been a case -- aside from the allegations at 9/11 -- that a multi-storey highrise skyscraper burns with fire, and then collapses.
Even to this day, when I speak to people, very few people are aware that 3 skyscrapers collapsed on 9/11
The twin towers are the best known skyscrapers that collapsed that had airline jets flying into them. But there was also the 3rd Tower No.7 that collapsed.
The 9/11 report hardly, or did not mentioned, the third tower No.7
There is an organisation - Architects & Engineers for 9/11 Truth (AE911T) - who collectively assert that WTC7 could not just have fallen down due to fire.
AE911Truth is a nonprofit organization that represents more than 3,000 architects and engineers who are calling for a new investigation into the destruction of the World Trade Center Twin Towers and Building 7 on 9/11.

e.g. the Grenfell Tower fire on June 14, 2017, in London - did not fall down.
e.g. the Dagenham Tower in London, burned on August 26, 2024, did not fall down.
You would have thought that, because of this historically-unprecedented case where a skyscraper falls down, ostensibly from fire, that massive amounts of academic engineering study and testing of the fallen structure would have been subjected to metallurgical testing. If the theory is that the fire causes the structural steel to fail, even a 2nd year Engineering student knows that the first step is to test the metallurgy of the steel. BUT the government took all the remains of WTC 7 and melted it all into scrap, so that no further testing can be done, with no peer reviews, and no transparency.
Do this test: ASK ANYONE YOU KNOW: how many towers fell on 9/11, and virtually 100% will say that 2 towers fell. I can't recall meeting any people (aside from people clued-up on so-called conspiracy theories) who are aware that THREE towers fell on 9/11. And that the 3rd tower fell without a plane flying into it.
From the viewpoint of structural engineers, that simply cannot happen - a skyscraper falling down due to fire. And there was no transparency, no peer viewed studies of the 3rd WTC7 tower.
A history-first occurrence of a skyscraper falling down due to fire -- and absolute secrecy in the testing, with no transparency, and no peer-reviewed studies.
Me, as a person with a university degree in a related field, my warning bells are blaring.
But when I ask people about the 3rd WTC 7 tower, typically people toss me off as a "conspiracy theorist". I have a friend who is an engineer, and he also is suspicious about this 3rd WTC 7 falling down without a plane flying into it.
C'mon people. A world's first, never before, never after, has a skyscraper ever fallen down due to fire. And total blackout, no transparency in the investigation. All the structural materials from WTC 7 now destroyed for scrap so that no further investigations are possible.
Funny thing is, 99.9999999% of people dismiss this as a "conspiracy theory".
