I’m not saying anyone would intentionally build an unsafe high rise.
It was a new technology at the time and what made it attractive is that it was fast and cheap as compared to the more traditional methods.
It was beyond comprehension that maniacs would fly fully fueled and loaded 767’s into the buildings, and it was a bleeding indeed they held up for another hour.
not trying to quarrel, but you are still saying it is unsafe. that just isn’t right. say what you will.
