Of course then there was the total idiot who packed loose ammunition in checked baggage!
When thrown down on the conveyor belt they bumped and at least one round went off.
The TSA has guides to allow the checking of Firearms in checked bags...
Apparently, this dim bulb didn't bother to check it out...
Nor, apparently, did the screener think anything of the danger of loose rounds rolling around in a bag!!!!!
We pay these people way too much for their obvious (extremely low) education level!!!!!!
By nature, "checked baggage" does not go through the conveyor belt TSA screening system. It goes from the ticket agent at the front counter to the hold of the airplane. No passenger has access to the hold of the airplane, Hollyweird movies aside.
"Carry-on baggage" does go through the screener and they are rather efficient at discovering items that do not belong. Though, to be sure, human error can exist.
Do you fly at all? Just wondering, as some of this is self-evident if one passes through an airport on a regular basis.
Also, as I understand, the bag that "exploded" during baggage handling had some primers within it. Primers are not loaded cartridges. They are the very small propellant caps that serve to ignite the charge of powder. They, in themselves, cannot really do much damage, and even if a complete brick were set off, the resultant "explosion" in an un-contained package like a piece of luggage would probably result in the bag being shredded -- and that's about all.
I have done a bunch of hand-loading over the years and often dispose of primers that I am suspicious of causing mis-fires by smacking them with a hammer or lighting them on fire in a coffee can. They mostly fizzle or pop like a roll of caps. The charge within them is very small -- about the size of a pin-head.
If ammo were carried loosely, and one was set off (difficult to do, as the primer must be struck directly) the bullet would not "fire" for any distance, as there is no container, such as the breach of a rifle barrel to contain the charge to force it in any one direction. It would mainly be like a fire-cracker.
Oh, and it is legal to travel with firearms and ammunition. It just has to be checked baggage and properly documented. Happens all the time.
