On one occasion I accidentally passed through security with with a Swiss Army knife in my backpack.
What's funny to me is that upon discovering so after getting to the gate I was much more worried about someone finding out I accidentally brought a pocket knife with me, rather than the possibility of someone else with nefarious intentions having also gotten past security with one.
Same thing happened to me; I had the Swiss Army knife in my backpack between a whole bunch of CDs. I wonder if the edges of the CDs somehow concealed the knife, or if the security person simply wasn't paying attention.
By the way, what's the likelihood of TWO people bringing a knife/bomb on board the same plane? Pretty small, huh? Hence, you should always bring your own bomb to fly safely! ;-)
