I havent been through airport security, but have gone through the local court house security when I applied for my CC permit. I dutifully emptied my pockets into the basket. I pulled a small plastic card from my wallet and stepped through the scanner.
It went off.
I presented the card to security. The card affirms that I have a total joint replacement and/or a permanent metal implant.
I was asked where the implant was and I answered that it was my left hip. The wand was passed over my left hip area (and only my left hip area) and I was passed through.
I hope airport security is a bit better.
I'm surprised that NASA hasn't stolen those rocket scientists away from court house security.
"I hope airport security is a bit better."
It isn't! I have had both knees replaced and have cards from my orthopedic surgeon, as well. I had them in hand when going through security. I set off the alarm. When I tried to show the agents the cards, but they didn't even look at them, just showed me to the "wanding area". I was wanded and patted down. Guess I passed -- they let me continue through.
