Tampa, Florida -- 10 News went behind the scenes Friday with the TSA at Tampa International Airport to see some of the dangerous things passengers have tried to bring on planes.
Security in the air is the TSA's business, and it's on the minds of people around the world after Malaysia Airlines flight 17 was shot down over Ukraine.
Pointing out brass knuckles, throwing stars, a hatchet, and clubs, you'd think Lee Kair is the curator of some medieval weapons museum, not the head of the TSA for Tampa Bay.
Security is the TSA's business and sometimes they find some unique, and dangerous, carry ons.
Kair displayed some of the unbelievable things people have tried to carry onto planes at Tampa International Airport: wwords hidden in canes, knives, grenades, and loaded guns have all been spotted by Transportation Security Administration screeners at TIA.
On the rise right now are credit card knives. They fit into a wallet, and fold in just a few seconds into a razor-sharp blade.
Kair said most of the tools aren't the improvised explosive devices that TSA experts expect serious terrorists to use, but they're still a clear threat.
"These items, obviously, are dangerous. We don't want them on-board an aircraft. And it's a distraction for our officers to be focused on these things," Kair said.
"We really want them to be focused on what we believe to be the number one threat to aviation security, which is the non-metallic I.E.D."
The TSA's showing even more amazing examples of what it has caught people with around America on its TSA Instagram account.
Stun grenades, loaded guns galore, even a whole arsenal in one carry-on bag.
Some are secretive, like knives tucked inside the sole of a boot, built into an iPhone case, or even disguised as a comb.
They've stopped stun guns that look like lipstick and a cigarette pack, and a Scooby Doo greeting card that was carefully concealing box-cutter razor blades.
As you read through the feed, sometimes you just have to wonder what these people were thinking.
A meat cleaver in St. Louis. A samurai sword in Boston. A razor-sharp batarang Batman tool replica in Buffalo. And an unreal six-bladed throwing star snagged in Las Vegas.
Kair says the reality is, most of the people who are stopped with something at security checkpoints just forgot they were carrying it, or they didn't know the rules about what you can bring on a plane and didn't realize what they brought was banned.
