The TSA wrote about grenades in particular: Year to date, the agency's officers have discovered:

  • 43 grenades in carry-on baggage.
  • 40 grenades in checked baggage
  • Officers at Dallas Fort Worth (DFW) discovered a live 40mm high explosive grenade in a carry-on bag in 2012. According to the TSA at the time, there was no nefarious intent. It was a soldier who made a mistake and in the end, no charges were filed.
