This is funny because just a few months ago, I was forced at Heathrow to chug -- not allowed to pour out! -- my entire water bottle that I had filled prior to my flight. The security person watched me do it and added, "bathroom's over there".

Why did you allow them to humiliate you like this?

Because flights are expensive enough that for most ordinary people missing one would set them back years or decades financially?

Famously Steve Jobs had a story about shaving time off of boot-up and equating it to saving lives on the concept of people sitting their waiting for the computer to boot up just lost that much of their lives. [1] I actually do believe there is value in thinking this way and it is one of my biggest arguments against TSA. Everything has a cost, including 'security' and 'safety'. If you look at the very real human toll,…

I almost exclusively take trains now because the experience of flying is one of repeated dehumanization, especially in the USA. First, if getting dropped off in a car (most American airports this is your only option), you must suffer being screamed at by traffic cops while trying to navigate a perpetually under construction dropoff area. You get one (1) peck on the cheek from mum before some uniformed individual wadd…

How many man hours and how much money have we wasted over security theater at airports? Has it been a worthwhile trade off?

No hijacked planes, no terror attacks?

There's also been none since I washed my hair this morning - certainly must be related!!

I have never understood how this was effective against a determined adversary. An arbitrary limit like 100ml is pointless when there is no limit to the number of times you can pass through the checkpoint.

It's also hilarious that the limit is the very metric 100ml, and not some even number of freedom units like 3 or 4 fluid ounces, like Jesus, George Washington, and bald eagles would have wanted.

UK uses the metric system. Why would anyone expect UK to follow the imperial system in $CURRENT_YEAR?

How did they force you to do that?

Anything a border official says is implicitly backed with the threat of, at a minimum, detention without trial and without basic humane treatment like access to drinking water. Heathrow has well publicised cases (and is not unusual in this).

Do you know that the 100 ml liquids gets scanned in the Heathrow airport? Many times they used to do a secondary scan too after the primary scan. I recall this very well because many times I was made to wait longer after my carry on arrived because they wanted to put the liquids through a secondary scan.

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…

Have you considered just going long Palantir?

there's nothing to really understand

Earlier quoted context omitted.

I think the point is we can afford massive machines for the TSA that are essentially paid for by the Federal Budget, and used by millions each day for free, but we can't do the same for MRI machines.

I think an MRI probably takes longer than the TSA scan so walk-through MRIs wouldn’t be practical.

Nobody or no item is getting an MRI at an airport. It's pretty common for people to conflate that with X-rays but MRIs work on a fundamentally different process and exclusively (outside of physics 101) requires liquid helium-cooled superconducting magnets to get anything useful.

too hyperbolic to take seriously

it would be incredibly inconvenient, and maybe missing other parts of a full vacation would set them back, but thats not the only reason people buy flights

Not because of a sudden outbreak of sanity, but because they have CT scanners now.

Yeah, I flew thru Eindhoven Airport in the Netherlands a few years ago, and I couldn't believe they let me through with water. The security used something I would describe as out of an Iron Man film, they were zooming around a translucent 3D view of my backpack. (It was on an LCD display instead of hovering midair, but I was still impressed. But the fact they let me keep the water was even more amazing, hahah.)

You can do realtime 3D flythroughs on CT scans with open source viewers. If you've ever had one, get your DICOM data set and enjoy living in the future.
