We fully support the layered approach. All security measures consist of layers. Some are known to the public, some are not. That's why the actual details of the security measures are distributed to the airlines in confidential documents, because there's a lot that we do behind the scenes. So layers provide a structure where it can be at the same time less invasive, because each layer doesn't have to be quite as obtrusive, yet when you put them all together you have a better system. So we fully support that direction.
We do believe that body scanners provide an improvement on the level of security provided, certainly over walk-through metal detectors. There are threat items that will be detected by the body scanner that would not be detected by the walk-through metal detector.
But as we've said, we would like the government to layer their program such that we are able to triage passengers so that the ones who are going through the more intense screening are the ones who have indicated a higher risk for some reason, or supplement it with a small portion of random as opposed to the larger reliance on random that we have at this point.
