It's easy to wonder why people didn't react differently, and absurd (now) to think that a few idiots with boxcutters can take over a few hundred people.
That tactic will never work again, and it probably wouldn't have worked on some people even then. Hard to say which camp we're in though since none of us were on those planes.
I generally enjoy his movies but he's an idiot to go spouting off about such things. Nothing good ever comes of that.

Up until then, the very few hijackings this country had seen (relatively speaking), had been peaceful (so to speak). Hijacker takes over plane, makes demands, plane lands somewhere, they refuel it in exchange for freeing passengers, plane flies on to whichever 3rd world country hijacker decides they want to go, where there's a 50/50 chance they get arrested, or treated like a hero. There was no reason not to suspect this same sort of behavior to happen again.
9/11 hijackers, however, were inherently more violent, and even killed the flight crews, it's believed, once they took over the plane. So unless there was a pilot dead-heading on that flight, or someone else with some sort of flying experience, those planes were pretty well f*cked once the hijackers took over, as there was no one else to land them.
And you're absolutely correct in saying that sort of thing won't work again (same with underwear and shoe bombers), since the first fool who stands up and makes a scene pretty much gets gang-tackled by whoever is around him, plus some (not all) flights have armed air marshalls on board.
OP, your title is somewhat misleading, however. The article I read, earlier today, said that Wahlberg had been scheduled to be a passenger on flight 63, the one that went down in PA, but didn't make the flight. His claim was not that he would have "stopped 9/11", but rather, that he would have stopped the 9/11 hijackers on that flight.
Pretty sure that, even if you think he's an awesome dude, he's still incapable of being on 4 flights at the same time.
