What’s the biggest threat to an airplane? A knife? A pistol? While these items can be dangerous, with hardened cockpit doors installed after 9/11, an improvised explosive device poses the biggest threat to aviation security today.

I’ve talked about using Advanced Imaging Technologies to detect non-metallic and metallic threats, including IEDs already, but today I wanted to talk about another technology we have to detect explosives hidden on people and in bags.While going through checkpoints, you might have seen officers using little white swabs at TSA checkpoints at one point or another. In case you had no idea what our officers were doing, they were conducting state of the art Explosives Trace Detection (ETD) tests. And all along you thought they were giving your items a complimentary cleaning…

ETD tests are used in checkpoint, checked baggage, and cargo environments. We swab things such as laptops, shoes, film, cell phones, bags, wheelchairs, hands, casts - you name it. Certain procedures call for an ETD test.

Basically, our officers run the white swab over the area in question to collect a trace sample. They then place the swab in the ETD machinery which analyzes the sample for extremely small traces of explosives. The test takes a matter of seconds.

In the TSA of the past, our ETD machines were anchored to certain checkpoints or baggage areas. This is a mobile technology and we’re now going to take advantage of that luxury.

Recently, we tested ETD technology outside its regular use at checkpoints and checked baggage areas, and confirmed its ability to be used in other areas of the airport like the gate to check for explosives residue on passengers. Why the move? Since the attempted attack on 12/25, we looked at ways to immediately strengthen security using existing technology and procedures in different ways. ETD is quick, good for security and cost efficient.

Sure, we’re improving the checkpoints with technology such as Advanced Imaging Technology machines, but we currently have ETD machines at every checkpoint in the country and this new procedure will help us beef up security. Explosive Trace Detection is a highly effective, proven technology.

So as you travel, you might be asked for a swab of your hands at the checkpoint or gate. It’s painless and quick. The swabs are disposed of after each use and will not be used on more than one person.This is another way we can help keep the flying public safe from attempted attacks such as the one on 12/25.For additional reading, check out these new articles on our expanded use of ETD technology:

What’s wrong with this picture? Put quite simply, it’s a fake. The picture (minus the black boxes) has been gaining popularity ever since it was used on several popular web pages and blogs.

The TSA Office of Information Technology (OIT) was able to determine that the original images used to make these pictures were taken from a stock photo website and doctored to mimic Advanced Imaging Technology (AIT) images. The doctored images are nothing more than full frontal photos (hence the black boxes) with the colors inverted. The image of the gun and belt were superimposed. This can be done with any basic image editing software.

It’s obvious that the woman shown on the left is not the woman in the doctored photos on the right. Notice that the bracelet on the right wrist in the clothed image does not appear in the doctored images. Her arms and legs are also in different positions in the clothed photo. It can be argued that maybe the photo was taken before she entered an AIT machine. Even so, just like X-ray images, hair does not show up in authentic AIT images and faces are blurred with a privacy algorithm.

Please take a look at this blog post to see larger versions of the images below and video of what AIT images actually look like.

Can you believe it? It’s that time of year again where turkeys head for the hills and people head for the airports. It’s the busiest travel time of the year and a time when people who rarely fly, or have never flown, take to the skies, so we wanted to provide some clarification and tips for those who might come to the blog looking for some information.

Here’s some guidance related to the most common questions we’ve been hearing lately. Please remember that each time our officers have to search a bag or a person, the line slows down.

The 4-1-1 on 3-1-1 (Liquids, Gels & Aerosols): Let me start by saying this. If you’re checking a bag, make it easy on yourself and just put your liquids in your checked luggage. That way, you don’t have to worry about 3-1-1. I know that suggestion doesn’t work for everybody. Some liquids are essential and some of you understandably would not like to pay to check your luggage. If you’d rather take liquids in your carry-on, please continue reading…

3-1-1 is the name for our liquid policy. You can read here for more details, but here is the gist of 3-1-1… Each passenger is allowed to take one clear quart-sized sealable bag and fill it with as many liquids in 3.4 oz or less sized containers that will fit, while still being able to seal the bag. Basically, don’t stuff it to the point where it won’t close.

Make sure you take the bag out of your carry-on prior to sending it through the X-ray, or our officers may have to search your bag.

If you have liquids, aerosols, or gels that are used for medical purposes, they do not need to adhere to our 3-1-1 policies and do not have to be placed in a bag. You may be asked to go through a TSA Family Lane (see below) so we can expedite the screening process. The liquids, gels and aerosols will need to be removed from your bags.

Answers to common questions: Stick deodorant is not limited to 3.4 oz or less, but gel or spray deodorant is. Also, any liquid makeup such as eyeliner should be placed in the baggie. That goes for perfume as well. Powder makeup is fine.

Family Lanes: Frequent flyers hate it when they’re in line behind a family, and guess what… families hate it when the frequent flyer is behind them tapping their foot and sighing. That’s why we created Family Lanes. They’re designed to let families take their time and ask questions without feeling rushed by the experienced frequent flyers who can zip through a checkpoint in no time. Also, as stated earlier, anybody carrying medically necessary liquids, aerosols and gels in excess of 3.4 oz may be directed to a Family Lane.

Foods: Pies are permitted, but they are subject to additional screening if our officers see any anomalies. (Additional screening of pies does not include our officers tasting the pie, no matter what they tell you…) Cakes, bread, donuts, turkeys, etc. are all permitted. If it’s a live turkey, you might want to have a word with the airline. Here is a list of items that should be placed in your checked bags or shipped: cranberry sauce, creamy dips and spreads (cheeses, peanut butter, etc.), gift baskets with food items (salsa, jams and salad dressings), gravy (mmm gravy), jams, jellies, maple syrup, oils and vinegars, sauces, soups, wine, liquor and beer.

Gifts: Wrapped gifts may need to be unwrapped. If there’s something in the gift that needs to be inspected, we have to open it. Our officers try their best not to mangle the gift wrap, but it’s not a guarantee and it also slows down the line for everybody else when we have to do this. It is suggested that you wrap the presents when you arrive at your destination. You also have the option of shipping the items as well.

Snow Globes: We are not in cahoots with the Heat Miser, but snow globes are not permitted in your carry-on luggage. They are sealed containers full of liquid that would have to be opened and destroyed to test. We’re not in the business of busting snow globes, so we suggest you place them in your checked baggage or mail them ahead of time.

ID & Boarding Pass Checking & Secure Flight: As you approach a TSA checkpoint, you will see an officer checking IDs and boarding passes. Please have your acceptable ID and boarding pass out and ready to present to our officer. If your ID is in a plastic sheath or other type of holder, it will need to be removed so our officers can properly inspect your IDs. By having your ID and boarding pass out and ready, you’ll help move the line along faster. The several seconds it takes to get your ID and boarding pass out might not seem like much time, but it really adds up when you’ve got people in line behind you.

Also, folks have had questions about the Secure Flight program and whether the name on your ticket has to match the name on your ID. The Secure Flight watch-list matching process occurs before a passenger even gets to the airport so if you get a boarding pass, the Secure Flight watch-list matching process is done. In other words, you are clear once you get that pass.

If you have lost or forgotten your ID, you will still be permitted to fly as long as you help us verify you are who you say you are by answering a few questions for us.

Inconsistencies: You may notice your screening experience at one airport doesn’t match the experience of another airport. We realize this happens, and some of it is intentional. While it can be a little confusing for our passengers, it also makes things unpredictable for those who might wish to do us harm.

Our officers also can use their discretion in different scenarios that allows them to use common sense and not abide by a checklist mentality that can be studied and defeated by those who wish to do us harm.

Shoes on Belt: We recommend you place your shoes on the X-ray belt as opposed to placing them in a bin. Why? It keeps the bins from getting too cluttered and allows our officers to get a better look at items to ensure prohibited items do not get on the plane. It also speeds things up when they get a better view and don't have to stop the X-ray belt for searches.

-----------------------------------The best piece of advice I could give a traveler is to arrive early if you have the time. No matter what happens, (aside from a flight being cancelled) if you get to the airport early, you should be fine. Worst case scenario is you’ll have some time to kill while you wait on your flight.

For any pilgrims who might be flying, be sure not to bring your muskets through the checkpoint and clothing with large buckles is discouraged as it will most likely alarm the walk through metal detector.

Is this all a bit too much to remember? Print out this handy dandy checklist (PDF) so you don’t forget anything.
