With the TSA screening 30,000 people a day, the agency hopes this reminds people why they often take time to check the most mundane carry-ons.

CHARLOTTE, N.C. — At least one passenger a week tries to bring a loaded gun on an airplane at Charlotte Douglas International Airport, according to the Transportation Security Administration.

TSA reports agents have already found 62 guns this year; 60 of them were loaded. That number's up from just 17 guns six years ago, but agents said TSA's greater focus is expanding its efforts to stop explosives.

According to the agency, fireworks are the biggest explosives ever found in Charlotte, but agents said it's only a matter of time until they find an actual bomb.

"It's not a question of if something's going to happen; it's a question of when something's going to happen," TSA Explosives Specialist Jason Brown said. "You got to look at it from a bad guy's perspective. We have to be right every time. Those terrorists only have to be right one time."

In recent weeks, TSA prevented passengers from carrying everything from a cane that doubles as a stun gun to a throwing star, knives, and loaded guns on airplanes. Agents caught them all at security checkpoints.

Brown, an Air Force veteran, knows there's an even greater threat out there. Over the last decade, TSA's expanded its presence of explosive specialists in Charlotte from one to seven agents.

"There's a lot of threats disguised as ordinary household items that can be dangerous," Brown said.

Brown showed NBC Charlotte training aids complete with hidden fake explosives. He said the baby doll, power drink bottle, remote control race car, and laptop are examples of normal things you'd bring on a plane that can easily hide deadly secrets.

With the TSA screening 30,000 people a day, the agency hopes this reminds people why they often take time to check the most mundane carry-ons.

"The ultimate goal of terrorists is still to attack the aviation system again," TSA spokesperson Sari Koshetz said.
