It's always shocked me how many 9/11 conspiracy theories people buy into, where there exists significantly more evidence that FDR knew of Pearl Harbor a day or so in advance, but allowed it to happen in order to push a reluctant US into war.
And you studied the engineering facts in detail? Ignorant people are often shocked by reality. Haven't you experienced that with for example explaining Bitcoin to relatives back in 2012?
This is yet another example of why I tend to believe I am just dealing with unwitting sheep and not conscious disinformation.
