Yes but one Glock trumps boxcutters. Flight 93 would have ended up without the passengers and crew dead if even one person produced a gun and stopped the terrorist armed with box cutters.
They only knew what the score was and decided to fight after at least some of the hijackers were barricaded in the cockpit. Hence, the use of a drink cart as a battering ram. The armed scenario would have only made a difference in the very start, when the use of force would have been least justifiable under the "business-as-usual" assumptions. After all, the gun wielder must consider which is more dangerous from their perspective: 1) a brief stay on a runway somewhere while political prisoners are freed; or 2) rapid decompression at 30,000 feet along with potential bystander fatalities. Airplanes are cramped; if you miss you hit either the wall or a passenger.
Of course, we all know now that the assumptions have changed and #1 is "rammed into a building", but they didn't know that at the time. You also must consider that there were four hijackers on the flight, even armed with boxcutters. The decision tree of our gun wielder now must include "can I rapidly take out four targets at different locations without causing #2"?
Like I said, guns aren't a panacea.
EDIT: On further reading, the case for our hypothetical shooter at the beginning of the flight becomes even more complicated. Voice recordings from passengers on cell phones calling out during the hijacking had multiple independent claims that the hijackers claimed to have a bomb. Now, our shooter must consider option 2 as "everybody dies". Remember, our shooter doesn't know yet that option 1 is "everybody dies." Deaf Smith, do you think it would be a responsible decision for our shooter to try and take out four hijackers thinking they may have a bomb? No, I think our shooter would have chosen option 1 given the information he or she had, done nothing, and by the time they knew better, it would have been too late.
