No way of knowing but at least we’d have tried.

I recall that some guy figured out that the muslims were going to be flying planes into the WTC some weeks or so before it happened.
He tried to warn people as well, and likewise he was also ignored.
Rick Rescorla had said for years that the next attack on the WTC was going to come from the air. His determination on this point is actually why so many survived, particularly from Morgan Stanley, as he forced evacuation drills for their offices in WTC. Regrettably, he was one of the few from that office that did not survive. If you do not know about him, read up and you will be amazed
