When Al-Qaeda themselves claimed responsibility, even with overwhelming evidence aside? Why were so many people still reluctant, I was researching about this stuff and was shocked to see people who I respect a lot believe in this
Operation Northwoods
Wtc7 a building not hit by a plane collapsed. With there being a video of the leaseholder saying they brought it down on purpose because it was badly damaged. Controlled demolition takes weeks of planning.
Plus the BBC reported on wtc7 collapsing too early, the building was still visible in reporters background
It is the only day in history that 3 steel buildings collapsed because of fire
Firefighters reported explosions going off in the basement just before the plane hit the building
Reports of pools of melting iron which allegedly can only be caused by thermite. Thermite would also be the reason why there was so much dust
The Pentagon; no good footage of the plane hitting. All the camera footage of surrounding business have been confiscated
For those who actually believe in these theories or are uninformed about them, consider reading this, which is backed up by sourcing and debunks every common 9/11 theory. https://rationalwiki.org/wiki/9/11
“Controlled demolitions take weeks of planning” because under normal circumstances, the risk of waiting is not that high. That doesn’t mean that subject matter experts aren’t capable of making an intelligent plan in a short period when a building is catastrophically damaged in heavily populated area where waiting can very easily result in more damage and more risk of casualties.
As for “melting iron”, if you’re talking eyewitnesses before the demolition, they have no idea what was melted. If you’re talking after, no shit they used demolition-grade explosives. It was a fucking skyscraper in the middle of a massively populated city that wasn’t stable. It had to come down.
