Whenever I have flown i set off the metal detectors at the airport. I have metal plates in my skull, facial bones, neck, legs and back. I have shown the pictures of the x=rays to no avail. I have not been on a plane too much recently, I grew tired of the jostling around, getting manhandled from the wheelcahair and so forth. last time I flew from detroit, the airline gave me the song and dance that I needed to have an attendant along with me for the flight. Too much BS. I simply replied i am a former marine and I do not need an attendant. I am independent and do for myself.
Flying is no fun. If i have to travel it is by car or by train. so far it has been quite nice on the train, but that is subject to change.
Your story is very similar to mine.
I get angry at all the hassle and then I end up with two overweight fatsos sweating over me!
I show them the proof that the metal I carry is due to corrective surgery, but then they are so damned stupid their feeble brains are incapable of comprehension.
