The News Minute | July 15, 2014 | 06:08 pm IST Every once in a while, the National Security Agency (NSA) officers manning airports, come across the weirdest of things people carry at airports, especially those they aren't supposed to. Hatchet, guns, grenade shaped vaping device, crackers and also an Improvised Explosive Device (IED) training kit; the NSA has found passengers carrying all these and more.And knives need a special mention: from those inside a hollowed-out book to one under the insole of a shoe, to one hid inside a Scooby Doo greeting card to comb-daggers, you name it and they will probably have it. What is surprising is that do passengers really think they can get away with these. May be they are just adventurous. The NSA often uploads these images on its Instagram page, which was created around an year ago, reports The Daily Beast. These images are not just fun to watch, but also will give you a good laugh with some of its captions. #TSACatch: A knife was discovered under the insole of a shoe at the #Detroit Metropolitan Airport.

We understand that instructors and others in this type of business need these items, but if an item looks like a real bomb, grenade, mine, etc., it is prohibited. When these items are found at a checkpoint or in checked baggage, they can cause significant delays because the explosives detection professionals must resolve the alarm to determine the level of threat. Even if they are novelty items, you cannot bring them on a plane. People that need to travel with inert explosives training aids should plan ahead and contact their preferred shipper about mailing the items to their destination.
