I just would like to add that there's no 100% security and it may even not be needed as the amount of efforts and resources to provide near maximum or near perfect security would be ridiculously high and intensive. It would be a folly to attempt it.

I view the current full body scan as excess and intrusive. . . . . .unless it required no human monitoring then again I must question the health risk posed by having gone through repeated scans in regular basis for those who travel a lot.

It's like saying that because crime is a possibility then all citizens must be considered a criminal unless proven otherwise. You just can't protect everything or at the same time protect one area intensively while being reckless in others. There must be balance in the coverage. I mean if some terrorist brought liquid bio-chemical terror substance would then all water or liquid be banned from the cabin?

Or that why not targeting the airport itself than trying to board the plane. I mean an airport is a symbol of authority and it is full of people. Then what? providing full body scan at the airport gate? If I was the terrorist I would avoid tight security and hit somewhere which is no less important or less symbolic but is much less secured.

What the pilot is trying to say has already happened here. A hotel was bombed not by terrorist posing as guest but by a terrorist posing as the hotel employee(florist) who never had to go through metal scan and belonging check. He actually had been working in the hotel for months
