So, are any of you saying that someone couldn't have enough Semtex or C4 surgically implanted into them (no need to worry about infection or being overly skillful) and detonate it aboard an airplane with catostrophic results ? The normal TSA measures would be ineffective (either pat down or scatter machines) because it would be inside the person. I'm not saying this is actually in the planning stages, but theoretically it could pose a major problem for screening at airports if someone could figure out how to do it without inadvertent detonation. Hell, you could kill more people in the crowded terminal than aboard the plane, and the entire terminal would be shut down indefinitely.
