We tried to look at it from an aviation safety and security point of view, or even a transportation safety and security point of view. We look at layers of measures. It's about building layers of measures that protect...but also as we make adjustments, putting in place different layers of measures. Testing of some kind or another, I think, is showing a lot of promise as an alternative to quarantine. We're not there yet, but the pilot projects are helping us build that evidence base that will allow us to make that decision down the road. I think some changing of the measures is going to be key to the successful relaunch of the aviation industry.
