So can unarmed passengers. And unarmed passengers have swarmed hijackers and taken them down. The hijackers' weapons (knives) are useless if dozens of people jump them. The doors didn't save the planes, the people did. And recall, the one plane on 9-11 that didn't kill people on the ground was the one the passengers fought back on. If they'd done it earlier, they may have lived. Dunno. But sitting still doesn't help at all. And armed passengers would shoot holes in the fuselage and other passengers, and in the melee the plane may crash. Use your hands. Can't blow out the pressure with your hands.
Numbers win against guns, if people know they will die if they don't fight. Best thing to stop a gun-toting idiot menacing a crowd? Crowd jumps him.Works every time. You personally can't, but three dozen of you can. Go for the guns first, grab those lovingly polished killing machines by the barrels and push them up/down and out of line, grab the hands, then his arms, and then pinch his corneas really hard and rip them out. He'll have second thoughts after that. Then kill him at your leisure. Or you can get really a good communal grip and rip his arms off. Or snap his neck. So many ways to make him stop dreaming of killing with his penis enhancing boom stick. Think communist Batman. Batman has the strength of one supremely trained indvidual, but you all have the strength of three dozen fat people who are REALLY scared and TOTALLY pissed.
