See SPO. See SPO Screen. Screen, SPO, Screen!

Keeping the flying public safe from curbside to cockpit is a major part of TSA’s mission. This post will hopefully provide some more insight about what’s going on before you even reach the security checkpoint.

Concerns about public areas in airports have been brought up time and again by security wonks and commenters on this and other blogs—and we’ve been listening.

Surveillance of non-sterile areas in airports is a no-brainer when it comes to mitigating risk in an efficient manner. There’s really no way to get around that. For a while now, several different TSA programs have been in place to satisfy this security need—and thus far, Behavior Detection has been getting most of the attention. However, Passive MMW, a.k.a SPO-7, might just steal the spotlight.

Since April 21, TSA has been testing and evaluating two tripod-mounted, highly mobile SPO-7 units at Boston’s Logan International (BOS). You may recall Blogger Bob’s post about Passive MMW back in September ’08; however, a few things have happened since then. Just as a quick recap, Passive MMW has been used in mass transit and maritime environments since 2007. In 2008, TSA tested the technology in non-sterile areas of Denver International and Minneapolis/St. Paul International during the 2008 Democratic and Republican national conventions.

The name “Passive MMW” may imply that this technology operates in the exact same way as the stationary Whole Body MMW machines at the checkpoint. This is definitely not the case. Both technologies are non-invasive and completely safe, but other than that, the only similarity is that both systems make use of millimeter waves in one way or another. To be clear, Whole Body MMW machines bounce harmless millimeter waves off of your body to generate a metallic image. Passive MMW on the other hand receives energy generated by an individual and the objects that they are carrying on their person. This energy can be detected by an appropriate receiver and can be used to detect anomalies.

Here’s an example of the image an operator would see:

As you can see, it looks a lot different than the robotic images generated by stationary MMW machines at the checkpoint. For this reason, Passive MMW machines and their operators will be in full view of the public in the non-sterile areas of BOS.

Security officers operating the Passive MMW will work closely with Behavior Detection Officers on the floor. If either group detects a potential threat, they will alert their counterparts. From there a variety of scenarios can occur, up to and including calling local law enforcement.

Signs will be placed in the vicinity of the screening area to make sure everyone is relatively well informed about Passive MMW:

So…Passive MMW…awesome idea right? Let us know what you think.

Blogger Paul's Visit to the TSIF

What’s a “TSIF” you ask? Well, it’s one of several hundred acronyms I’ve had to learn since I’ve been here—but this one is special. The TSA Systems Integration Facility is a newly renovated 128,000-square-foot test facility located at Ronald Reagan National Airport. Here’s a little tour through the facility. Enjoy!

Traveling With Homemade Gadgets

The internet, as I am sure you all would agree, is a marvelous thing. People from coast to coast and around the world have used it for everything… researching term papers, reading the news, paying bills and even writing blogs. The internet is also a marvelous tool for those looking to save or spend money.

These tough economic times have led many passengers to search for discount flights on the Internet and even, as we have learned at TSA, used the Internet to learn to make homemade gadgets. It’s these gadgets that have caused some …. How shall we say, second and third looks at the checkpoint. By second and third looks I’m not talking about just TSA, I’m talking our Bomb Appraisal Officers (BAO) and local bomb squads.

In a matter of minutes this morning, Blogger Bob found Internet sites with “how to build” instructions for a desulfator and radio receiver in a common mint tin (a desulfator is used to put high voltage pulses into a battery), a guitar amp out of a cigarette pack, a mint tin made into a guitar and a circuit bender made from an old plastic parts kit. While none of these items are threatening in and of themselves, imagine what a mint tin with wires, batteries and a switch looks like in an x-ray machine.

While each of these items gets the award for creativity, it might be a good idea to put these items in your checked baggage or maybe even leave them at home. However, if you have to bring them with you, maybe letting our folks know that you are the master innovator could prevent any unnecessary surprises from occurring. Nonetheless, expect some extra scrutiny…

What do I mean by further scrutiny? Yesterday, March 24, an item very similar to those described above, was blown into a zillion pieces in Palm Springs, California, because neither our officers, our BAO or the local bomb squad could determine with 100% certainty the item didn’t pose a threat after seeing it on the x-ray.

So, if you are traveling with a homemade charger, amp, desulfator or anything with batteries, screws and wires sticking out of it that could be deemed out of the ordinary, please tell us. It will probably allow us and the local bomb squad to help keep your items in one piece, not a zillion. Probably…

Clarification Update: 03.26.2009 1137

Based on the comments, Nico & I felt a clarification was needed. This post purposely never mentioned a passenger because the bag was left unattended and there was no passenger available to interview. We're not implying that you cannot travel with these types of items, we're just pointing out that they could be of concern, or possibly even hold you up a little bit. Listen, we think these things are cool too, but this is just a friendly "heads up" and not a threat.

Also, explosive detection systems would not identify these types of items in checked baggage, because they aren't explosives. Our checked baggage machines use CT technology and can actually recognize and alarm on potential explosives.

Smooth...

Lotion is designed to keep you smooth, but apparently not smooth enough to fool our Millimeter Wave (MMW) machines. Recently, a passenger concealed a 4 oz. bottle of lotion on their person for the sole reason that it was expensive and they didn’t want to lose it.

Of course, many of you are saying, “Thank the heavens for the TSA. Without them, a harmless bottle of lotion would have made it onto an airplane. “

While the sarcasm is expected, what you don’t know is our intelligence has shown us that terrorists with dry flaky skin are unable to fulfill their missions. So it’s vital to keep all lotions off of airplanes.

I kid, I kid, but on a serious note, what if it wasn’t lotion? What if it was liquid explosives, or a block of plastic explosives?

The success story here is not that we kept a bottle of lotion off of a plane, but we found an intentionally hidden item on a passenger. We found a hidden item and knew exactly where it was without having the passenger undergo a hand-wanding or patdown.

Pilot Program Tests Millimeter Wave for Primary Passenger Screening

This week, TSA began testing MMW technology in the place of a metal detector at Tulsa International Airport to assess passenger throughput and acceptance.

Currently, 18 airports have millimeter wave equipment installed at checkpoints in a “secondary” screening configuration, which means that metal detectors are still the primary method of screening passengers. At these airports, randomly selected passengers and those requiring secondary screening can be screened by millimeter wave technology as a non-invasive alternative to a pat-down from an officer.

In Tulsa, instead of walking through the metal detector, passengers will go directly through the millimeter wave machine. A passenger can opt not to go through the unit, but will go through the metal detector and get a pat-down instead. Signage at the checkpoint informs travelers about the technology and lets them know that using it is voluntary. We’ve included one of the signs below.


So far the pilot seems to be going well, as noted in an article in USA Today. In the first three days of primary MMW at Tulsa, 3,780 passengers have been screened using the technology and only 8 people have opted for the metal detector and a pat-down.

In addition to the security benefit of whole body imaging – it can detect metallic and non-metallic threat items – the technology also reduces the need to pat-down passengers with hip replacements, prosthetics and other surgical implants. At airports without Whole Body Image machines, when passengers alarm the metal detector, the alarm must be resolved through a hand-held metal detector and a pat down. This often takes two to four minutes as opposed to about 15 seconds with millimeter wave.

For every person who is hesitant to go through the millimeter wave portal for whatever reason, there are 100 people with metallic surgical implants that are rejoicing. Here is a quote from Thomas Frank’s USA Today Article:

“For passengers with metallic hips or knees, the scanners were a relief from metal detectors, which invariably sound alarms that lead to pat-downs. ‘I walked through, raised my arms and was done,’ said a beaming Larry Brenden, 43, of Albuquerque. ‘I was like, what, no pat-down?"

And yes, whenever we talk about whole body imaging we get lots of comments and questions about privacy. We suggest checking out 60 Minutes correspondent Leslie Stahl’s commentary on millimeter wave or this article by the producer of Ms. Stahl’s segment. For anyone just hearing about millimeter wave and wanting to know more, please read Blogger Bob’s two previous MMW posts: [link 1] [link 2]. The short version: the technology is completely safe, WBI images are never transmitted, printed or stored, the officer at the machine cannot see the image and the officer viewing the image cannot see the passenger.

In the next two months, the pilot program will expand to San Francisco, Las Vegas, Miami, Albuquerque, and Salt Lake City.

If you have the chance to go through a millimeter wave machine – in primary or secondary – please share your thoughts here on the blog.

**Update:

TSA’s partnership with European civil aviation authorities has also had a significant impact on TSA’s decision to begin the Primary MMW pilot. A Primary MMW trial at Schiphol airport in the Netherlands has been underway since late 2006. Prior to TSA’s pilot program, TSA technology experts met with Dutch civil aviation authorities and technology experts to discuss the process and recent results.

***Addendum:

Including the above, three signs will be on display at the security checkpoint for airports participating in the Primary MMW pilot. See the other two below. All three are currently on display at Tulsa.

Paperless Boarding Pass Testimonial

While scouring the internet for TSA related information, I came across an interesting testimonial regarding paperless boarding passes from a passenger who travelled through the Detroit Metro Airport. (DTW)

“Checked in online for my flight today and saw a new option show up for an E-Boarding pass at DTW (note: only for direct flights). I had to try it, clicked and within 20 seconds a SMS message showed up on my phone with a link to the E-Boarding pass with a barcode on my cell phone (PDA). Not wanting to risk missing my flight, I also went back in and printed a boarding pass as a backup, that I never had to use.

I had a lot of questions on how it would really work, especially with having to show your boarding pass when you walk under the TSA metal detector and have to show your boarding pass and you are not allowed to bring your cell phone through. So he is how it went today:

TSA Boarding Pass Check - they have a new bar code reader that you hold your phone up to and it reads the bar code and you show them your ID to match the name that shows up on the screen. They then give you a Tuit (a Poker Chip with TSA on it).TSA Screening - Just like normal, except you hand them the Tuit instead of showing them your Boarding Pass with the TSA checkers initials on it. Sorry, they have to keep the Tuit, I was hoping to start a new game to see who could collect the most Tuits in 1 year.WorldClub - I use the Amex Plat. Card, so I have to show a Boarding Pass, ID and the Amex Card. They also have the same bar code reader and I put my phone in front of it and it scanned. Good to go. Gate - I held my phone on top of the normal reader the GA's use and it read it and I boarded without any problems. The only comment from the GA was the the last guy who tried it, didn't work. I'm sold, will be using the new E-Boarding Pass from now on. Didn't slow me down; however, I did get a lot of stares/attention from fellow pax's as I pulled out my PDA at screening, WorldClubs, Gate. “

I’d be interested to see if any of our other readers have tried this yet. So, if you've used this, please tell us about it.

Pilots for Pilots

One of the requirements of the 9/11 Bill asked TSA to look at ways to enhance security by identifying airline flight deck crew members (pilots) and giving them a faster way to get through security.

TSA is now piloting a couple of ways to meet this requirement, which will get pilots to their planes a little faster without compromising security.

The Airline Pilots Association (ALPA) is currently testing a system called CrewPass at Baltimore Washington Thurgood Marshall International Airport (BWI), Pittsburgh International Airport (PIT) and Columbia Metropolitan Airport (CAE) in South Carolina. At these three airports, pilots using specified exit lanes approach the Transportation Security Officer at the podium and present their airline badge. The officer enters the pilot’s badge number into a device. The pilot’s face appears on the screen allowing the officer to ensure that both faces match up.

Concurrently, testing of another system is being done at BWI called Secure Screen. Developed with Southwest Airlines, this program is currently in use for participating Southwest Airline pilots only flying out of BWI. Similar to CrewPass, they arrive at a specified exit lane and approach the officer on duty. They present their pilot’s badge and at the same time enter a “clear key” - similar to a USB drive - into a reader. The reader displays the photo of the pilot and waits for the pilot to place their thumb or finger on the clear key. The system verifies that the biometric thumb print matches the fingerprint being placed on it. This system combines identification verification with a biometric component.


Commercial flight deck crew members are responsible for the safety of hundreds of passengers at any time and are trusted to operate million dollar aircraft on a daily basis. Allowing them to move more efficiently through the security process, while also being able to verify they are who they say they are, fits into our risk-based security approach.

More on Passive Millimeter Wave Technology

Some folks are getting the wrong idea that the SPO-7 passive millimeter wave technology used at Denver and Minneapolis-St. Paul airports during the recent conventions is a mobile Millimeter Wave portal and can see through clothing. That’s not the case. These are two separate technologies that look for threats in different ways.

The Millimeter Wave portal - the booth you walk into at checkpoints in certain airports - penetrates garments and provides an image. The SPO-7, which uses passive millimeter wave technology to detect threats from a distance, produces an image, but it’s simply the type of image you would see on a video camera. Images are not stored.

The SPO-7 unit consists of two separate sensors and a monitoring location. By simultaneously comparing the illumination levels from two locations on an individual’s body, the SPO-7 detects potential threats such as suicide vests and other improvised explosive devices (IEDs) that are hidden under individuals’ clothing. On the screen, it produces a light, using a red-to-green scale, that suggests anomalies such as the presence of explosives. That's why the screen and the officer viewing the screen doesn't need to be in a remote location.

Security officers operating the SPO-7 will work closely with Behavior Detection Officers. The teams will be equipped with wireless headsets to communicate with each other about possible concerns. TSA also partners closely with local law enforcement who will respond if called.

Unlike the stationary (and large) millimeter wave portal, the SPO-7 is mobile and only requires a few hours of training for use. This comes in handy to provide an additional layer of security in specific areas, in both the aviation, mass transit and maritime environments.

In crowded public areas such as ferry terminals, mass transit stations and most recently, airports, the SPO-7 works without breaking passengers’ stride.

And lastly, to address safety and privacy concerns, the SPO-7 does not shoot X-rays or any other type of radiation at people. It merely measures energy that emanates from the human body. Signage is prominently displayed where the SPO-7 is used to notify the public. SPO-7 enables TSA to add an unpredictable security measure without adding inconvenience to passengers.

The SPO-7 pilots will continue at the Denver and Minneapolis-St. Paul airports for 60-90 days.

So, the two key things you should take away from this post are:

The SPO-7 cannot see through your clothing.

The SPO-7 does not project X-rays or any other types of radiation.

Here are some screen shots of what the operator sees:

New Security Technologies Make Airport Debut

Blogging has been light this week, with some on the team out for end-of-summer vacations and Bob's out taking care of his new baby.

So this week, as one political convention comes to a close and another is about to start, we wanted to highlight a story on our website about two new technologies that have been deployed in the two convention city airports. Those traveling through Denver and Minneapolis-St. Paul might see these explosives and threat detection technologies that have previously been used in other modes of transportation and can be flexibly deployed to airports.

The technologies are passive millimeter wave, a mobile technology which has been used in maritime and mass transit to detect the characteristics of explosives hidden on the body. It is completely safe, non-invasive and does not store information. A hand-held spectrometer can penetrate sealed containers in seconds and identify a wide range of solid and liquid explosives using laser technology.

To learn about other ways TSA and other Department of Homeland Security components are working to keep convention travel and sites safe, check this out.

We'll get back into the regular swing of things next week, and we hope all of our readers enjoy a safe and fun Labor Day weekend.
