A lot of the real recognizable benefits of SMS tend to be, shall we say, almost more on the industrial side of the operation. We see tremendous improvements in things like cargo handling, maintenance, ramp activities, typically activities that are in themselves inherently perhaps a little more dangerous because of the environs you are working in. As I say, they are a little more industrial. What you find is that in the reporting processes that are used within SMS, the risk assessments that are used, you see real, identifiable reductions in accident rates, these types of things.
That's why I made the comment about whether crashes are prevented being much more difficult to quantify. However, when you take a look at the way SMS works, particularly on risk assessments, so that any change to your operation, any additional point on a route, a change of equipment, the risk analysis and other processes that are part of the SMS world really do focus the attention and help be proactive within an organization.
