As I suggested in my remarks, there are a number of hardware and software technologies out there that support safe drone operations, whether it's guards for the props, geofencing, or return-to-home functions. There are low battery indicators so that you know when you're running out of power, or there's an automatic return to home before the drone simply lands.
There actually is a pretty good list that I could share with the committee of various things that would support safe operation and prevent the runaway scenario you're talking about. I'd be happy to share it, Madam Chair, with the committee, if there is interest.
