'This isn't another 9/11': Homeland secretary says as U.S. flights grounded

Well, there's no fear to the public and people that as I want to make sure we say this again, there's no reason for the public to be afraid or scared for your loved ones. This isn't another 9/11. I just can't repeat that enough. People are making that assumption because that's the last time we had a nationwide ground stoppage. This is a telecommunication outage. This is much different. There are reports that the FAA was rolling out a new AI traffic control system today. Has there been any link between that? We're looking at that. As we investigate what caused this, you always got to assume that as many cyber attacks that take place, that you make that assumption. So, but as of right now, that's not known. So we're going to continue to work. The first thing we want to do is make sure we restore the communications, we get all the flights on the ground, and then we get back normal operations. But we're going to continue to work to find out what the root of the cause is.
