Isn't it ironic that the most effective way to stop those fanatics and weirdos is exactly what security staff doesn't like to see on airplanes and tries to discourage from getting close to airplanes: crew and pax !!!
There's still obviously lots of ways to smuggle "weapons" on aircraft. But everybody onboard is so scared now that if you wanted to do a "9/11 attacks - episode 2" you'd need to fill half the plane with terrorists to have a chance to reach the cockpit. Or try to "express-mail" yourself on cargo planes.
I can already hear the security freaks say: "we need more security, we need more people, we need more equipment, and we definitely need more full cavity searches !!!"
The only example not going in that direction (that I can think of for the moment), is the three guys arrested in Jeddah last week before they got into the plane. All the others who've been stopped in time were already IN the plane. Any other example ?
