Hand grenades. Swords. Loaded guns.

These are the weapons travelers are trying to board planes with. After the Transportation Safety Administration (TSA) confiscates them, it takes pictures and posts the items on its Instagram account with the hashtag “TSACatch.” According to the TSA, firearms are the most frequently discovered items. In 2013, 1,813 firearms— five a day — were found at 205 airports across the nation (and 81 percent were loaded).
