Structurally, cockpits were never designed to deny access to all humans once the door is locked. Not military or civilian. Neither is your house...I don't think. Rescue is factored into the design. The cockpit is a locked office with restricted access. Not any different from the Oval Office door. Except for the armed response!
No doubt, if an intruder were to gain entry by force into your house, you are justified in the use of deadly force. This is an option that we as pilots do not have...yet!
I propose that we return to the golden age of air travel...when people dressed up to fly, and the flight crew could carry a concealed weapon. It is probable that today's news would have been different if the pilots had a chance to end the situation early.
Ironically, the day prior I flew our B-737 into New York (La Guardia) Airport. A low cloud layer obscured all of Manhattan except for the upper 30 floors of the WTC. We both commented on how majestic the towers looked as they poked above the clouds(and how fortunate those people are to have an office with a view above the clouds). [b]Godspeed to those people.[/b]
