I can't speak to whether or not they are happening more often. I guess just by the nature of the fact that more aircraft are flying and the fact there certainly is more coverage oft hose types of things, it's probably more noticeable.
But from an airport perspective, one thing I would say is that if we look at the Transportation Safety Board watch list, we feel there is a direct correlation between two items: unstable approaches and aircraft overruns. If an aircraft approaches a runway too high and too fast, the end result, typically, can be an aircraft or a runway overrun. In those types of situations, what we'd like to see is not only a complete focus on the reasons, but also a look at the situation of unstable approaches and what that means and the root causes. Addressing those issues in and of themselves can minimize the potential for runway overruns.
