I'm not generally a fan of conspiracy theories. I don't believe there is anything deceitful about the accepted version of events in either 9/11 attacks, Diana's death, the Moon Landings, Covid, Megan Markle, and the vast majority of other events that are often theorised about.
The incident at the top of this post, the Pan-Am bombing farce, Dr David Kelly's death, possibly Jeffrey Epstein, although I think that was an 'assisted suicide' rather than a straightforward murder to order, and possibly that Lee Harvey Oswald was not the only person to shoot at and wound JFK. Jack Ruby did not act out of anger either.
I don't claim to know what the truth behind things is, but the idea that investigators found the passports of the hijackers two days after 9/11 just beggars belief
They also found millions of other intact items from the remains of both the planes and the contents of the buildings. Why would finding the passports of people who were very definitely on board those flights be all that unfathomable? Are you also one of the people who claims a missile and not a plane hit the Pentagon, based on nothing other than the shape of the hole it made, and completely discounting the eye witness testimony of the hundreds of unconnected and independent witnesses who actually watched a plane fly into it?
