Ah yes, nobody is allowed more than 100 ml of liquid.
Becuase, you know, there's just no way that 100 ml of explosives could
possibly cause a devastating explosion. Or release a deadly nerve gas
and kill everyone on board. And there's no way that three suicide
bombers could all get on the same plane, each carrying 100 ml, together
making 300 ml in total. Or, for that matter, there's no way you could
hide more than 100 ml of liquid about your person without somebody noticing.
Oh, wait... I think my brain just switched back on.

I'm wondering why they don't put humans through the X-ray machine. I'm
guessing because then anybody who does a lot of travelling is going to
start receiving dangerous amounts of X-ray exposure over time... So
maybe we just need to invent a scanning technology that's less harmful.
Oh, wait. We already have several. Ultrasound, NMR, PET and so on. So
I'm guessing it's just too expensive or impractical. (Ultrasound
apparently requires close contact with the item to be scanned, or else
the item must be immersed in liquid. Neither is especially practical.)
Then again, for any given scanning technology, there is probably
something that's invisible to it. Ultrasound sees only changes in
density. X-rays can't see liquids, only dense solids. And so on.
The again, maybe we're looking at this all wrong. I mean, why the
obsession with airport security? Currently, anybody who feels like it
can nip down to their local friendly chemist, buy a few chemicals, mix
'em together, walk down the street to their location of choice and set
off a devastating explosion. And nobody will stop them. Indeed, it seems
utterly implausible that it's even physically *possible* to detect that
somebody is about to do this and try to stop them. They could be
anybody, anywhere, any day or night.
Then again, how many people actually do this? Not that many.
Interesting perspective: Road traffic accidents kill ten people PER DAY
in the UK, apparently. And yet I don't see anybody freaking out and
saying we need tougher controls on the roads...
