While we're on prevention as well, I think we've heard some great testimony from all the witnesses on things like registration, education, licensing, which you mentioned briefly as well. When it comes to other strategies to prevent incidents between users and commercial aircraft, or any aircraft for that matter, we've learned a bit about geofencing. You mentioned potentially investing in geofencing around sensitive areas and certain altitudes.
Are there other preventative measures we could take or more specifics on geofencing that you think we could recommend the government look into?
