Stikkord: <span>saline solution</span>

Et veldig interessant intervju som tar for seg mange spennende aspekter ved flysikkerhet. La meg trekke ut et par gode spørsmål fra Schneier:


By today’s rules, I can carry on liquids in quantities of three ounces or less, unless they’re in larger bottles. But I can carry on multiple three-ounce bottles. Or a single larger bottle with a non-prescription medicine label, like contact lens fluid. It all has to fit inside a one-quart plastic bag, except for that large bottle of contact lens fluid. And if you confiscate my liquids, you’re going to toss them into a large pile right next to the screening station—which you would never do if anyone thought they were actually dangerous.

Can you please convince me there’s not an Office for Annoying Air Travelers making this sort of stuff up?


How will this foil a plot, given that there are no consequences to trying? Airplane contraband falls into two broad categories: stuff you get in trouble for trying to smuggle onboard, and stuff that just gets taken away from you. If I’m caught at a security checkpoint with a gun or a bomb, you’re going to call the police and really ruin my day. But if I have a large bottle of that liquid explosive, you confiscate it with a smile and let me though. So unless you’re 100% perfect in catching this stuff—which you’re not—I can just try again and again until I get it through.

This isn’t like contaminants in food, where if you remove 90% of the particles, you’re 90% safer. None of those false alarms—none of those innocuous liquids taken away from innocent travelers—improve security. We’re only safer if you catch the one explosive liquid amongst the millions of containers of water, shampoo, and toothpaste. I have described two ways to get large amounts of liquids onto airplanes—large bottles labeled “saline solution” and trying until the screeners miss the liquid—not to mention combining multiple little bottles of liquid into one big bottle after the security checkpoint.
