A long series of hijackings with firearms resulted in metal detectors.
Armed hijackings plunged nearly to zero.
Then there were the plastic explosives. Pan Am #103 anyone?
CAT scans and other three dimensional color X-ray devices were installed.
I don't know of any other planes blown up with plastiqué since then.
Then we had good, old fashioned fist fights. 9/11 was the result.
Now they have banned non-ticketed passengers from the gate areas. They are also implementing armed soldiers, facial scans, oral questioning, and so on.
But will any of these measures *really* be foolproof?
What would be to prevent someone from having a few pounds of C-4 SURGICALLY IMPLANTED in his body, that can be detonated either by pressure change, or a small remote control device, just like what you would use to enable/disable your car alarm? After all, most of these people are willing to die for the "cause" they believe in, so the above scenario might not be all that far fetched at all. Should we ban keys and "alarm remotes" as a premptive mesure against something like that happening? Should all passengers be escorted onto planes blindfolded and strapped to their seats for the duration of the flight? I suppose that COULD work, but who would go for it?
How would we prevent that? Is flying "in the buff" as someone in another thread suggested be the answer? After all, if someone has a large, recently stitched up incision wound, that could give them away.
But seriously folks. How much are you willing to put up with to have the illusion of a "safe" flight?
What do you think the public is willing to put up with?
What about privacy concerns? Should profiling and privacy take precedence over risk?
Will it get to the point that people are so scared and/or frustrated by the flying process that the industry will shrink down to a fraction of what it is now, opening the door to say, a railroad renaissance via high speed rail?
Is the treatment worse than the disease?
Are we fighting the symptoms and not the disease?
CAN terrorism REALLY be stopped?
Are we really any safer?
Or are we just jerking off and putting on a show to make people THINK they're safer?
