The privacy questions are enormous. Now, I understand that's not really your jurisdiction.

I think if you just kept them out of residential areas and maybe with a waiver for police, that might solve the problem.

Well, I am very worried about two things. One is safety, and the other is privacy.

I think the pilots have to be certified. We have to know who's doing this, because it doesn't take much to put a munition on it once you've got the know-how.

Consequently, they are real spy machines. Now, is that something we want in commercial service in the United States of America?

Well, I'm going to introduce legislation to require it.

Here's my concern. I understand that. So you could have thousands of these things in the air. How do you control them?

I can envision drone fights in the air, drones cracking into each other.

Yes, but not in commercial aviation.

I believe the integration of drone technology poses serious privacy risks--especially the danger of unwanted surveillance of the individual.

I know they wouldn't legally carry munitions. But there's nothing to stop someone from arming one with munitions, and that's my big concern.

I rise to introduce the Transnational Drug Trafficking Act of 2013 with my colleagues and friends, Senator Charles Grassley, Senator Richard Blumenthal, Senator Heidi Heitkamp, Senator Amy Klobuchar, Senator Tom Udall and Senator Ron…

I think we would all agree with that. It's what's outside of that that's of deep concern.

Under the 2012 Federal Aviation Administration (FAA) Modernization and Reform Act, the FAA is directed to develop a 'comprehensive plan' to integrate unmanned aircraft into the national airspace.

I think that we as a country need to look at this technology very carefully.

I can envision drone fights in the air, drones cracking into each other.

There's so much that needs to be looked at very seriously, I think, before we do this.

I know they wouldn't legally carry munitions. But there's nothing to stop someone from arming one with munitions, and that's my big concern.

I think it's a real hazard and that we really need to be able to identify abhorrent behavior.

I think if you just kept them out of residential areas and maybe with a waiver for police, that might solve the problem.

I appreciate the action. I know it's controversial, but I can tell you the complaints are large and the distress is large.

I'm going to introduce legislation to require it.

Here's my concern. I understand that. So you could have thousands of these things in the air.

But there will be many more drones than there are private aircraft, most likely.

I would just like to urge you to give your attention to this subject.
