Explosive Trace Detection

By now, I’m sure most of you have heard about or seen firsthand pieces of TSA security equipment affectionately referred to as “puffers.” Officially known as Explosive Trace Portals (ETPs), passengers enter the machine stationed at the security checkpoint before proceeding through the metal detector. Several “puffs” of air are released in an effort to shake loose trace explosive particles on the passenger. Over the years, TSA has determined that trace portals do not meet the requirements for operational suitability due to frequent maintenance issues. TSA also determined that more reliable and effective screening technologies have become available since ETPs were first introduced. For these reasons, TSA has decided to phase out this technology.

ETPs were first deployed to airports in a pilot capacity in June 2004. At the program’s peak, 94 of the 207 units originally procured by TSA were deployed to 37 airports. Over the years, TSA gathered performance data on several variations of the technology.

As the ETP pilot progressed, it became increasingly apparent that tweaks and fixes were unable to resolve ETP maintenance issues caused by dirt and humidity common to any airport environment. In the summer of 2008, TSA made the decision to begin phasing out ETP technology.

All things said and done, TSA spent approximately $29.6 million on explosive trace portals. Of this, approximately $6.2 million was spent on maintenance on the 94 deployed units. Currently, there are 33 ETPs deployed to 15 airports. ETPs that are still in use at airports continue to support a dynamic layered screening approach.

Earlier this year, TSA opened a brand new testing facility called the TSA Systems Integration Facility (TSIF). At this facility, TSA tests a variety of security screening technologies in simulated airport environments. This facility will allow TSA to more effectively measure operational suitability prior to deployment.

What's in a Name?

Starting May 15, when passengers purchase airline tickets, they will be required to provide their name as it appears on the government-issued ID that they plan to use when traveling. This is the first phase of a new TSA program called “Secure Flight.”

So…if you plan to present a driver’s license , purchase tickets using your name as it appears on your driver’s license. If you plan to present a passport, purchase tickets using the name that appears on your passport. (Here is a list of acceptable forms of identification.)

But rest assured, the system will be pretty flexible. For the near future, small differences between ID and reservation information, such as the use of a middle initial instead of a full middle name or no middle name/initial at all, should not cause a problem for the passenger.

Secure Flight is a multi-phase program developed by DHS that matches passenger information against federal government watch lists for domestic and international flights. Before Secure Flight, airlines themselves were responsible for matching passenger information to the federal watch list. As Secure Flight is implemented, TSA will begin to assume responsibility for the security program.

So what exactly do we mean by “watch list matching”? When you purchase an airline ticket your name will be compared to the “No Fly” and “Selectee” lists, which are distilled from the FBI’s terrorist watch list.

Individuals confirmed to be on the Selectee list, will automatically be subject to secondary screening, but could still be allowed to fly. If an individual is confirmed to be on the “No Fly” list, he or she won’t be able to fly within, into, or over the United States. The number of people that appear on these lists is extremely small, so chances are you won’t run into issues at security checkpoints because your name is on the watch list.

After August 15, domestic airlines will be required to collect (and passengers will be required to provide) date of birth and gender in addition to name (as it appears on the government ID). By providing these pieces of information under the new Secure Flight program, cases of mistaken identity will be virtually eliminated. For passengers who have had problems in the past, this means that you’ll be able to print your boarding pass at home before arriving at the airport. It also means that your 6-year-old won’t be misidentified as someone on the Selectee or No Fly lists.

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!

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.

TSA’s Work Abroad

With more than 2450* daily inbound flights to the U.S. from all over the world, TSA has put a major focus on collaborating with foreign aviation authorities and sharing best practices, intelligence, technological innovations and expertise so that flights coming into the United States have the same level of security as those departing the U.S.

In collaboration with DHS and Department of State, TSA coordinates transportation security bilaterally with individual countries and multilaterally through major international aviation-related organizations including the Group of Eight (G8), the International Civil Aviation Organization (ICAO), and the Asia –Pacific Economic Conference (APEC). Twenty-two TSA Representatives (TSARs) are deployed worldwide to serve as DHS’s “boots on the ground”; interfacing with international partners, coordinating the DHS response to transportation-related terrorist threats and incidents, and facilitating the security assessments conducted by TSA’s security specialists at more than 300 airports in more than 100 different countries. TSA’s international teams have successfully vetted 100% of airports with direct flights into the United States.

Here’s a brief overview of some of TSA’s international activities:

On August 1, 2008, TSA JFK Inspections and Screening coordinated security measures with Emirates Airlines to ensure the successful arrival of the first commercial A380 ‘superjumbo’ jet direct from Dubai.

For the 2008 Beijing Summer Olympic Games, TSA coordinated security efforts with the People’s Republic of China. This partnership began in the summer of 2007 when U.S. Federal Air Marshals hosted a training exchange with members of the Chinese Air Marshal Program at our facility in Atlantic City. From July 19 until August 24, TSA successfully coordinated security operations at China’s Joint Operation’s Center with teams deployed at airports in Beijing, Shanghai, and Hong Kong.

When thousands of anti-government protesters took over Bangkok’s Suvarnabhumi International Airport (BKK) on November 25 of this year, TSA responded by sending a team to assess the risk associated with flights departing for the United States. The team was able to ensure the security of direct flights to the United States by December 6, allowing Americans to return home safely.

In a brand new 2009 initiative, TSA plans to deploy special teams of veteran security experts to various international locations to assist host nations with enhancing and sustaining local aviation security. St. Lucia will be the first nation to participate in this initiative, and TSA’s assessment team will work with the St. Lucian Ministry of Tourism and Civil Aviation to assess training needs, equipment, and aviation security legislation.

TSA on 60 Minutes

TSA and aviation security was featured in a 60 Minutes segment with Lesley Stahl last night. Transportation Security Officers LaDonta Edwards (BWI airport) and Gary Wilkes (DCA airport) were interviewed along with TSA Administrator Kip Hawley.

We gave CBS an inside look at TSA’s new training for all officers designed to calm the checkpoint, better identify threats and improve security by changes in how officers engage passengers. Our officers appreciated the time spent talking with Ms. Stahl, and she was certainly surprised to learn that one of the strangest things officers had seen come through the X-ray machine was a baby in an infant carrier. (Seems some people take the “Never wake a sleeping baby” mantra a little too seriously.)

Ms. Stahl had access to the TSA Operations Center, also known as the Freedom Center. This is our main information center, where analysts monitor the entire transportation network and connect TSA with the Department of Homeland Security, Federal Aviation Administration, FBI, and other law enforcement and security agencies. It is the kind of place you would hope exists in the post 9/11 world.

During an airport visit, Ms. Stahl and Kip Hawley operated the multi-view X-ray machines at BWI and saw how the improved technology helps officers find suspect items by highlighting areas of concern on the screen. While in the remote viewing location for the whole body imager, Ms. Stahl was surprised to see that it was not the “pornographic” image she thought it would be.

The piece also includes Bruce Schneier, security expert (and blogger) who calls some of TSA’s measures “security theater.” We agree with Bruce’s comments in the piece about terrorists being able to change their tactics every time something is banned or receives added scrutiny (guns, box cutters, liquids, shoes, etc.). That’s why we’re using new officer training and technology to be more proactive and going after hostile intent through the use of Behavior Detection Officers. These officers are trained to look for involuntary behaviors people trying to evade security display and can distinguish them from the behaviors of the average frazzled passenger late for a flight.

We understand that some checkpoint security measures annoy many Americans, but because of the intelligence information gathered from around the world, TSA deems these measures are necessary. We appreciate any opportunity to highlight our officers, enhance public understanding about why we do what we do, and show what motivates us every day in order to keep air travel safe.

In-Line Baggage Screening: Increased Security and Convenience

Most Americans know that all checked luggage is required to go through screening before it goes onto the plane, but what happens behind the scenes? One of two types of screening systems are being used at airports across the country. “Stand-alone” inspection systems can often be found in the public lobby of an airport terminal near the airline check-in counters—although they are sometimes installed in locations outside of public view. These labor-intensive systems are typically used in small airports or in specific zones with low baggage volumes.

“Stand-Alone” Baggage Screening System Schematic

“In-Line” inspection systems, unlike their stand-alone counterparts, use heavily automated networks of Explosive Detection Systems (EDS) able to handle thousands of bags each hour at busy airports. More than half of the 2 million people that fly each day go through airports with in-line baggage screening systems.

These systems use conveyor belts to automatically screen, sort, and track baggage. Multiple EDS machines are linked to a centralized control room and several “resolution rooms.” When a bag triggers an alarm, the bag’s image is transmitted to the resolution room where trained officers determine whether a physical inspection is warranted.

If a physical inspection is required, the bag is routed via conveyor belt to an inspection area where TSA officers screen the contents of the bag while under constant supervision by closed circuit TV. A notice is placed inside each bag that is physically examined indicating an inspection took place. If there’s a problem afterward, the CCTV footage can be used to determine if a particular bag was indeed hand-searched and by whom. Once an alarm is resolved, the bag is placed back on the conveyor belt and sent on its way to the plane.

Other benefits of this technology: since the in-line system is heavily automated, the number of physical injuries sustained by officers due to lifting baggage is reduced, TSA can track each and every bag throughout the process.

Just Back from BWI - A Thanksgiving Checkpoint Report

I just spent five hours working alongside Transportation Security Officers at Baltimore Washington International's Southwest Terminal A to help out with the traditional Wednesday-before-Thanksgiving-rush. Thing is, no rush ever occurred. Sure, there was a steady flow of traffic through the checkpoint without much of a break, but the queue never really grew beyond 30 people.

Officers were out in full force manning five separate lanes-including the Family Lane that rolled out November 20. While families and those with special needs certainly appreciated Family Lane availability, the checkpoint was moving so smoothly, that all lanes were readily able to handle all types of passengers regardless of their particular situation.

Like many of my fellow headquarters colleagues who volunteered for the Thanksgiving weekend, I helped officers with bin removal and replacement in the lanes. I also helped spread traffic around to each of the five lanes to expedite the entire process. As I stood behind the Travel Document Checker podium, a frazzled mother approached me and asked:

"Is that the Family Lane over there?"

I replied, "Yes it is."

"Should we go over there?"

"Do you have any medical liquids over 3.4 ounces?"

"Nope. We're traveling pretty light here."

"Then you're good to go right where you are [which happened to be lane 2-the shortest line at the moment]."

Another good thing I noticed during my time at BWI: pies, cakes, and other holiday food items went through checkpoints without incident-though some items were subjected to additional screening.

The holiday spirit was on display as another passenger approached "TSO Dave" while he was helping bags through the X-ray machine and said: "You guys are doing a heck of a job today." Little things like that mean a lot.

While things went smoothly for the most part, there was one interesting moment around noon. As I was chatting with passengers and helping them with their bins, I noticed an Evian bottle with less than three ounces of red liquid in it under one of the metal tables situated in front of the X-ray conveyor belt. I picked it up, and let an officer know where I found it. He quickly placed the bottle into a little bowl and sent it through the X-ray machine. Based on the image displayed on our end, the officers was able to verify that the liquid was not in fact dangerous and disposed of it.* I love technology.

There's been plenty of articles out there about the decrease in traffic over the 2008 holiday season, but it was very clear from my first hand experience at BWI that TSA's officers, expeditious security features, and prepared travelers certainly helped the flow of traffic today.

It was an awesome experience to work with the BWI team and experience firsthand what they do every day.

Hopefully my experience at the checkpoint will continue through Sunday and Monday. Look for another post from my colleague Christine, who will be volunteering at Washington DC-Reagan National Airport on Monday.

Quick update: Traffic has just started to pick up (2:45pm), but all five lanes are still running smoothly. Family Lane is being used primarily by families. Special needs individuals (wheelchairs, etc.) are still being taken care of in all lanes.

Happy Thanksgiving and safe travels to all.

* Clarification: While X-ray can detect many things, it cannot detect all types of liquid explosives. That's why the 3-1-1 liquids rule was put in place in September 2006 and will remain in place until a technology solution is tested and deployed. In this case, when an abandoned item was found at a checkpoint, officers used available technology to screen it to ensure passengers' safety and then disposed of it.

Thanksgiving Travel Projected to Decrease this Year

This Thanksgiving season will be the first time that the Air Transport Association of America (ATA) has projected a decrease in holiday passenger traffic since 2001. Higher fuel prices combined with reduced consumer spending have led to a projected 10% drop in the number of passengers and flights in the 12-day period spanning November 21 (Friday before) through December 2 (Tuesday after), as compared to the same period in 2007. (Click here and here)

Even though passenger traffic is expected to drop, as always, TSA has ramped up holiday staffing at the checkpoints to ensure passengers get through smoothly. It always helps to come prepared so you can help keep lines moving. Check out the Travelers Page (click here) for special holiday information regarding food and gift items, tips on how to pack, and a list of things you shouldn’t bring on a plane.

While wait times may vary from airport to airport, last year, the average wait at peak flying times was less than 13 minutes during the holiday weekend. The busiest travel days are usually the Wednesday before Thanksgiving and the Sunday/Monday after.

Here are projections for busy airports this Thanksgiving, courtesy of Orbitz.

Family/Special Needs Lanes Coming to All Airports in Time for Thanksgiving Travel

The Diamond Self Select Program [link] started back in February 2008 at Salt Lake City International Airport and is now operating in 48 airports. The program allows passengers to proceed through the security checkpoint at their own pace by selecting one of three lanes: Black Diamond (for Expert Travelers), Blue Square (for Casual Travelers), and Green Circle (for Families, those with special needs, and those unfamiliar with TSA procedures.)

Today, TSA announced that the Family/Special Needs Lane (Green Circle) will be implemented at every security checkpoint across the nation by November 20, 2008—just in time for the busy Thanksgiving travel season.



While many frequent travelers appreciate the Black Diamond Lane, we’ve also seen a great deal of success with the Family Lanes. Families and those with special needs appreciate the extra time and assistance, and our officers have seen the number of prohibited items in these lanes drop significantly because passengers have more time to divest.

From a risk management standpoint, directing all medically necessary liquids that exceed the 3-1-1 limits to a dedicated lane makes sense. This move is the first step in the path forward on liquids that Kip Hawley wrote about last month [link].

What do passengers need to know about this development? If you’re flying after November 20th and carrying medically necessary liquids in containers larger than 3 ounces, you should use the Family Lane. Medically necessary liquids include: baby formula, breast milk, insulin, cough syrup, contact lens solution, and prescription medications. These liquids must be presented to a TSA Officer for additional screening, which should usually take less than 2 minutes.
-
If you don’t have any exempt liquids, proceed with your baggie to any other security lane. Remember, you can pack any amount of liquid in your checked luggage.

Blogger Paul's Intro

It is with great pleasure that I begin my first official blog post at the TSA. I arrived at HQ last week with aspirations common to most recent college graduates. Pumped full of “unique” ideas that could potentially change the entire world, I decided to start with the TSA. My plan was simple and straight forward. I just needed someone in a position of authority to lend me their ear.

While my “unique” ideas are certain to be called into question from time to time, as a recent college graduate, my writing will attempt to synthesize an outsider’s perspective with insider knowledge. Having monitored the ongoing debate between TSA authorities and the public, I’ve discovered that both sides are (believe it or not) in agreement more often than they realize.

Since I don’t have the frontline experience like my colleague Bob, I’ll be spending the next few weeks meeting people here at TSA, spending time at local airports, and monitoring the blogosphere to see what other folks are talking about to come up with blog topics to cover.

Since I’ve come on board, I’ve spent some time at Baltimore Washington International Airport’s Southwest Airlines’ Terminal B learning about Checkpoint Evolution [link]. Like many travelers, the first thing I noticed was a wall of holograms and a faint blue glow from the lights lining the perimeter. As I wound my way through the line, I was greeted every so often by portraits of security officers (sometimes out of uniform) with brief bios below their pictures. Clearly, the intent behind these signs is to remind us that Transportation Security Officers (TSOs) are people just like the rest of us, and dedicated to their security mission. It was interesting to see that some are veterans or former law enforcement officers.

So here’s the overarching theory: when the checkpoint environment is calm and the majority of passengers lined up at a security checkpoint are relaxed (or as relaxed as anyone can reasonably be when trying to catch a flight), a suspicious person will oftentimes stand out in stark contrast from the rest of the crowd. Also, encouraging clear communication between security officers and passengers helps passengers understand the “why” behind the rules, and facilitates the flow of traffic through the security checkpoint.




Sure, lights and signs are nice, but they are not in and of themselves the main focus of Checkpoint Evolution. Aside from targeted technological improvements—such as Whole Body Imaging, advanced technology X-ray machines, and inter-officer communication via ear-piece—the greatest benefits to security and passengers’ experience come from one thing in particular: enhanced training. TSA officers I met at BWI have completed a 16-hour training course (although training is ongoing) that focuses on explosives detection, intelligence analysis, and techniques for improved passenger engagement, with the ultimate goal being threat detection. This training will be given to every frontline employee, and has already started in some airports.

I asked the BWI officers what they thought of Checkpoint Evolution and the response was very positive. “It has made our job a lot easier,” said one of the officers. “Striking up a casual conversation with passengers allows us to get a better feel for the situation—not to mention that it makes our day more pleasant.”

Next, I hope to attend some of the training sessions to see what they’re like and get more feedback. I’ll report on that later.

Now for the all important question: What do passengers think? I haven’t had the chance to chat with any Checkpoint Evolution veterans just yet, but if you’ve been through BWI’s Southwest Airlines’ Terminal B, let us know what you think by posting comments.
