I kid you not, I knew a guy who was an absolute "storyteller" (I think everyone knows at least one of these types of people) who claimed that he walked through an airport metal detector about 10 years ago with one and it didn't go off....
bhahahahah.....what a handjob.

Perfectly plausible!
In November 2001, 2 months after 9/11 when everyone was on "high alert" and unarmed NG troops were all over the airport, I walked thru the metal detector at TF Green and didn't set off the alarm. I had a full-size police badge in my back pocket (ID case) that I forgot to remove and put in the bin. I then realized that the metal detector NEVER went off on anyone during the 1+ hour we were in line waiting to go thru the one security checkpoint at that airport . . . no doubt it was shut off (unsure if they knew it or not). I had to keep my mouth shut about it until I exited SeaTac many hours later, otherwise they would have shut down the airport and re-screened everyone.
This blows my mind. The screws & plate in my arm set off the detectors at that airport.... I still think the other guy's story was BS.
