The ADM can jump in on this, but we are looking at the issue of fatigue. As you said, it is a really complex phenomenon. It's not just the number of hours, but it also depends on people, depends on the full cycle. More and more studies are being done on this. There have been demands from the air industry, for example, the pilots.
This is actually something that is one of our top priorities, because as you said, there's a mix of accidents and also economic impact. Those accidents cost a lot of money in the end, so it's better to have a system in place that ensures that fatigue does not become an issue from a safety perspective.
