With the criteria posted by some of the above members, I wonder if anyone knows or has thought about; who checks the security personnel? Am I to asume that they ( the security people) are above all suspicion. And that we, as flight crew's seem to be under constant suspicion? I mean, honestly, are the airlines also being investigated? Are the airlines to be doubted in the way they carry out their security measures? As far as I know, all airline personnel are constantly checked on an internal bases. They ( the airlines) also have a data base of all their flying and non flying employees. That's the whole point of issuing an I.D card!. .The INS, for one, have copies (formats) of practically every airlines ID card, that operates in and out of the USA.. .I go back to a previous posting; there must be a way of establishing some sort of a data base? . .I just hope that time and experience, will result in the elabration of a better system. I also hope that the pilots unions can intervene and help the various agencies in sorting this mess.
