My favorite TSA story: my father was an airline pilot during 9/11. A few months after the new "safe" TSA security checks were implementer he lost his small travel bag, so he grabbed another small bag from his closet, threw in some toiletries and went to work. SIX MONTHS LATER he found his original bag, and when he dumped the contents out of his "temporary" bag there were two small boxes of 9mm ammo! So for 6 months he had been going through the newly minted TSA security screenings, at least 6 times a week, with 50 rounds of ammo, and was never caught.

I was part of the first batch of TSA screeners in my home town, and I can say your story tracks. While there were plenty of intelligent people who worked for the TSA (I'd like to think I was one of them), there were a large amount of people who were hired because they were struggling to find work for a variety of reasons, many of which were personality and ethics related. Things often got missed. We would have trainings where security failures from other airports were shared with us... some of those failures included fully loaded firearms being missed on the x-ray... which is something that most people could have seen without any training at all. Complicating the issue, the terrorists behind 9/11 used items which the FAA allowed on flights. After 9/11, the government stepped in and fired all of the private contractors, many of which had years of qualified experience, and hired largely a brand new screening force. While some private screeners migrated over to the TSA, many screeners opted not to since it would have resulted in a cut in pay. A more rational, less expensive and far more effective approach would have been to simply tighten the security already in place, and implement new trainings with existing staff. The irony here is that while your father traveled with 50 rounds of ammunition, there were plenty of old ladies who had fingernail scissors thrown away. Finally, I always thought it was funny that we even had to screen the pilots to the degree we had... if a pilot had bad intentions, they hardly needed a knife or a gun to follow through.

If you think about it, all these lithium powered devices we carry make for much better explosives, and yet they are allowed on every flight (well aware of the energy restriction). With a burning temperature of 2000 Degrees Celsius, what's stopping someone from using a couple of electronic devices in conjunction to do terrible damage? The fumes alone are deadly already... We've got to rethink our airport and plane security in general. The current measures, reliable as they are, remain more of a show than actual security. Anyone with serious intent can find their way around it, its all far too fragile of a system. Other than that, great video as always :)

I've just been last weekend to Berlin Branderburg Airport BER and it was my first time seeing one of those smiths security scanners. I was so confused why we wouldnt have to take out laptops or water out anymore, and wanted to search for this new technology, but didnt find anything. Now i stumbled upon this video, and it makes a lot more sense. I just think that as it is right now, not everyone sees the signs of taking out laptops, water etc, so this will take longer. (I was travelling in a group of 70 people and quite a lot of them just took out their laptops and emptied their bottles out of routine.) But when everyone knows those new scanners, it could be really time and nerves saving for everyone. Great Vid!

Also, each element has jumps in X-ray absorption in different places, so if you really want to isolate a certain element, you can X-ray it once a little below and once a little above and the difference shows you that element (e.g. iron has a jump in absorption at 7.1 keV, so 6.7 keV and 7.5 keV). That way you can find and confiscate all the steel nail clippers hiding among a bunch of loose change, to keep everyone "safe."

The security agent told me it didn’t matter and somehow my other bag got additional search (for my toiletry bag) while my backpack with the liquids didn’t require any extra search

It's interesting to see the mix of experiences and opinions surrounding airport security measures. From anecdotes about successfully bypassing security with unexpected items to frustrations with inconsistent procedures across different airports, it's clear that airport security is a complex and sometimes flawed system. While advancements like new scanning technology can improve efficiency, it seems there's still room for improvement in terms of effectiveness and consistency.

I still show up over an hour early, you never know what kind of events can drastically increase tsa times. For example, I live in Texas and had to travel for work a day after the eclipse. My flight was leaving at 6am so I show up a little before 5am thinking it would be a ghost town that early. I of course forgot everyone traveled to Texas for the eclipse. The tsa line was 45 minutes long and growing longer by the minute. I barely made it to my flight. Always show up really early, you never know what might hold you up.

Thanks for the great explanation! A few weeks ago, I went through Amsterdam Airport and noticed that the security staff was asking people to put their laptops in their carry-on luggage. I also noticed that there were no longer a bunch of bottles of water piled up in the trash cans. Thanks to your research, I now know why! Thanks again!

Was at SFO last year, and one of the TSA was loudly encouraging people to go through the line where they didn't have to take anything out, or take their shoes off. They had a mix of two types of machines, I opted for the "leave shoes on and everything in the bag" option.

Security theater. My friend accidentally brought a Bowie knife in her carryon and no one caught it because she’s a super cute blonde in her 20s and they were flirting with her. As long as they hire people who couldn’t get hired at Starbucks, TSA will never be actual security. No one is going to blow up a plane with a liquid explosive.

I work for Smiths in Germany! It's honestly such cool tech and cool to see some coverage on KZread :) the diffraction scanner you were talking about launched last week (if anyone is curious it's the SDX 10080 XDi, there's a video of how that works on KZread as well)

The first I heard about these was actually warnings to travelling film photographers about how they can fog film (plain X-ray machines these days are low dose enough that you can get away with sticking most film through them, but these devices, just like medical CT scanners, use a lot more radiation than their 2D counterparts)

I remember a few years ago I managed to bring 500ml water bottle through Schipol security, I was confused why it was allowed but I don't care at the time because I have extra water on a long flight. Now it all make sense.

I have worked for a couple of years as a researcher on X-Ray phase-contrast imaging, which I guess is what you're hinting at at the end of the video. I am still quite doubtful regarding its use for airport security, but I could be wrong and I honestly haven't given it too much thought. As far as I am aware right now, there are mutliple competing ways to achieve this and the debate for the most efficient one is not yet settled, but my money goes on speckle-based imaging. It was also quite funny to see the article by Yalçin being displayed here, since I showed it to a colleague recently when we discussed sample density measurements.

All these engineering advances, but then the last time I went through one of those high tech stand up person scanners where they make you lift your arms they got worked up with me because I had a tissue in my pocket ...

I always carry a small thermos flask with me whenever i travel. Most of the time i empty it before going through security and then just refill it once im through. But sometimes i forget to do that and carry it through filled with water. However interestingly i never once got stopped, i got stopped for plenty of other things, chargers, dongels and keychains and all sorts of other rubbish. But never the water bottle. I dont know if its because the scanner couldn't penetrate through the double walled steel thermos, or wether they knew it was water and just never bothered to stop me. Or wether they just wilfully let it slide because so many people were bringing the same thing in and they could tell what was a water bottle and what was something else. At any rate even if there was anything suspicious they would just make you drink it or they themselves would just take a sip to confirm, and most of the time they'd just let you go through anyway.

You can't imagine how much I smiled when the fast lines opened up in Munich with the new scanners. I noticed the queue with these new "Smiths detection" machines was much faster, so I went for it. I noticed people weren't taking out anything out of their bags. When it was my turn, I asked: "Do I have to take stuff like laptops and headphones out?" and to my surprise the security guy said no. I felt so good! I had just been through security (that normally takes an hour, or more) in 12 minutes. And it's not like it was a slow day at the airport, this was around Easter! I used to arrive at the airport 2 hours before my flight with the old scanners. Now I still arrive 1 hour before my flight at the airport and I usually have a good 45 minutes of free time. 10-15 for security, no ID checks, because Shengen. I love it! Traveling around Europe became faster and more enjoyable.

When I was listening to the beginning of the video, I was wondering whether or not you were talking about dual energy scanning. They've started to use them in hospitals now for patients in planar x-rays to assess soft tissue better than your standard single energy x-ray.

3:30 If I am correct, some heavier metals also have some forms for x-ray as a colour. This is used to identify metal elements via a electron microscope

@5:55 Nice Johnny Harris reference!

In Milan (ITA) airports it's more than 3 years that you are no longer required to take your laptop out of the bag because the scanners can analyse it. And, if I remember correctly, also Atlanta, GA airport no longer requires you to take the laptop out of the bag since a few years.

I just came home from Rome (FCO) and the security lines there had signs saying you can leave your water botlle & bag of liquid containers in your carry-on bag. I didn't pay much attention to the scanner, but it must've been one of these. Hopefully, we'll get these at Toronto Pearson soon.

The scattered wavelength of the radiation, their frquency and their intensity, at particular wavelengths can easily be used to detail and image...

Micro-X has developed a smaller and more reliable airport scanner system with no moving parts. They also have a mobile bomb scanner that uses backscatter X-Ray technology the size of a large cereal box, it’s also able to take small measurements. It uses backscatter X-Ray removing the need for a reflector plate, thus making bomb detection a whole lot more safer. Micro-X also has a mobile CT machine that’s small and lightweight with no moving parts. This can now be placed into ambulances, helicopters and planes. Some amazing engineers at Micro-X

So the “solution” to the problem is that we should be better screened at the airport and not that the security theater should finally be stopped?
