there is actually a science change that happened, and it's not (entirely) just politicians changing their mind. The big thing going from X-ray (2d) to CT (spin an X-ray machine around and take a ton of pictures to recreate a 3d image) did a lot to let security people see inside of a bag, but the hitch is that if you see a blob of gray is that water, shampoo or something else? The recent advance that is letting this h…

Can this X Ray bit flip memory or damage NAND?

It's a specific liquid scanner that's done on bottles that have been pulled aside for extra scanning (at least, that's what Frankfurt was doing a couple weeks ago)

Frankfurt has been doing that for ages (2 years now?). They just got better scanners. But they don't cover all terminals or checkpoints, so you gotta know your way around.

I don't recall it in Frankfurt last summer, but it was definitely going earlier this month. Though, they've got a weird security setup for some of the gates, so I'm sure it varied from gate to gate. Dublin and Edinburgh have had it for a while too, Dublin since last summer. Really speeds up security.

I've never done that yet I've never had any trouble finding water past security or even on a plane?!

Some airports charge money for water after security. Others disallow even empty bottles at security screening

> Others disallow even empty bottles at security screening

I haven't encountered this. Could you name some?

It's super frustrating losing the contents of your water bottle and then having nowhere at all that you can refill it.

I think all UK airports have easy to find water bottle refill stations

The ones at LHR suck though. Often broken/next to no water pressure. Easier to just ask a coffee shop.

Airport prices in the UK for recreational travel work like so: Flight from London to Barcelona: £16 Bottle of water past security: £5 Train to airport: £26 Taxi enters drop-off area for 30 seconds: £7 A person who wants to get the advertised flight at the advertised price has to be very careful.

Yeah it’s got out and out criminal at this point. Not sure why we should accept a £6.40 charge to drop someone or collect someone from an airport when that’s the actual function and necessity of using an airport. I got charged £100 at COUNCIL OWNED Manchester airport for picking up a friend who accidentally had put themselves in the drop off zone rather than the collect zone. Just completely vile and disgusting corporatism at every single level.

Price of water from water fountain (to be found on basically any western airport and most non-western I've ever been to) - 0.

I get your approach, but say where we live (Switzerland) if you have something not tightly around your body like a fleece jacket, you have to take it off and put it through scanner, this is default. Sometimes they still ask me to go down to t-shirt even if its obvious I don't have anything in pockets.

Not worth the hassle for something that is mostly free and probably healthier compared to plastic bottles stored god knows where and how long. I'd imagine if they catch you, you are going for more detailed inspection since its obvious you didn't forget 1kg bottle in clothing you wear by accident.

This just adds confusion as to the purpose of all this. The motivation behind the liquid limits is that there are extremely powerful explosives that are stable water-like liquids. Average people have never heard of them because they aren’t in popular lore. There has never been an industrial or military use, solids are simpler. Nonetheless, these explosives are easily accessible to a knowledgeable chemist like me. The…

most of airport security rests on the notion of going over a series of long tests will elicit unusual (fear, stress) responses from malicious actors and these can then be flagged for even thorougher checks which will then eventually lead to discovery, banning or removal of luggage so it's not the test accuracy by itself but rather then the fact that these tests are happening at all

This kind of thinking is as legitimate as believing lie detectors work, i.e., not at all.
