I travel commercially to get to my aircraft and probably fly on average about once per week. I have a femural nail from an accident years ago but am “assured” the scanners don’t pick it up. I also have an abutment (metal screw) in my skull for a hearing aid but again am assured the scanners don’t pick it up. I get “hand patted” about 75% of the time so have now learned to smile sweetly and just get on with it.
What does get me is that when I get to the airport where the jet is, I am allowed to walk out to the aircraft without passing through security with my bags etc - but when I come back to the terminal to walk the boss through I have to go through security just as he does. And the logic is....????
