BOSTON — The TSA is getting ready for one of the busiest weeks of the year at Logan Airport.
Next week is spring break for many Massachusetts schools and the rush out of town will start as soon as Wednesday.
On Tuesday, TSA officials showed off some of the hidden dangers they have found.
Starting Friday, 70,000 people a day will go through security checkpoints at Logan as the spring break getaway begins. TSA explained why some of the security measures used at Logan are still in place.
"It's really up to the imagination of the evil mind of the bomb maker, where can they hide the explosives," said TSA spokesperson Lisa Farbstein.
From books to shoes, to hats, even a deck of cards. Security screeners at Logan showed off the training devices used to show where terrorists can hide bombs.
"Intelligence tells us that terrorists are very focused on transportation, very focused on airports and airlines," said Farbstein.
The TSA says agents are very good at finding hidden explosives but they need passengers to follow instructions about what items can go in carry-on bags.
"You've got your laptop in your carry-on bag, take it out, put in the bin, nothing above or nothing below it," said Farbstein.
Here's why. Agents say devices like laptops and tablets can be altered to conceal detonators and plastic explosives.
"People sometimes object to taking out their laptops and electronics and sometimes object to taking off their shoes, but we want to remind them that the reason we're doing it is for their security," said Farbstein.
As for what's the most common item of concern found at security checkpoints, the TSA says it's knives.
"You see kitchen knives, butter knives, carving knives, sushi knives, you see tactical training knives, Boy Scout knives, Swiss Army knives, credit card knives, you see fishing knives, hunting knives...." said Farbstein.
If you're heading to Logan over the next week, leave extra time to get through security; two hours for domestic and three hours for international travel is recommended.
