I am hoping someone here knows the answer I am looking for.... I had surgery on my arm (broken) a few years ago and have 2 titanium plates in my arm as a result. When I had the surgery done I was supposed to get a card that said I had them in my arm due to the surgery for when I go through security at airports. I never received it. My question is, will I need this card at Kennedy Space Center? I think I read something on their site about having to go through metal detectors on the way in.
