This thread might make me quit this site. 9/11 certainly did happen, and people certainly did die. I know a few people whose relatives and the like were in there. Were they in on it? There were definitely without a reasonable doubt planes that flew into the WTC. There is some speculation on my end about the logistics of how those 2 planes could have brought those towers down, but to outright up and completely deny that it ever happened is just one of the most ridiculous things I have literally ever heard. More ridiculous than a flat Earth.
As for the Virgin Galactic lcd-window argument, I have a question for you.
If they have no problem with doing a fake launch, never leaving the ground or whatever, and just playing what would be seen on screens... Don't you think they would have been doing that for like 10 years now? If there's nothing really that has to be accomplished other than aesthetic appearance and a convincing video reel - then they've been missing out on a whole lot of money for years. Surely the evil greedy conspirators would have thought of this earlier.
