It’s true, why are you so agressive? The towers had increased security from two weeks prior to the attack until just a day before (fitting). They claimed that maintainance were taking place which could be true, but could also likely be a cover-up for planting explosives. Some way the explosives got there either way as it’s impossible for a skyscraper to collapse in that way after a impact from mererly a airplane.
And idk what you mean with wannabe engineers, they have their degrees and the only reason that you are discrediting them is because they say something else than what you think. I also urge you to rethink your ideas about ”conspiracy theories”, as that label is just slammed on everything that doesn’t comfort with the official stories on anything, ignoring the facts presented by said ”conspiracy theory”. While many of these conspiracy theories indeed are ridiculous, 9/11 is not and governments have just labeled it a conspiracy story to make people shy away from questioning it.
