Transportation Secretary Sean Duffy unveiled a new plan to modernize the air traffic control system aimed at improving safety and reducing delays by the year 2028.

The overhaul would cost tens of billions of dollars and replace more than 600 outdated systems, including old wiring, the kind of wiring that affected computers at Newark Airport,

which has led to hundreds of cancellations and triggered new questions about the safety of the air traffic control system.

So what we use today is copper wires. We were one of the last institutions, last businesses that actually use copper wires.

We shop on eBay to replace parts to fix our equipment in the system that keeps you safe.

But the plan faces big hurdles.

We're joined now by our aviation correspondent, Miles O'Brien.

Miles, it's great to have you here.

So first, is what he said true that you have air traffic controllers

going to eBay to find parts to fix the system?

I hadn't heard that detail, Jeff, but it doesn't surprise me a bit. We're talking about technology

that really looks like it belongs on the set for Apollo 13 or a computer museum, literally floppy disks, which people of a certain

generation wouldn't even know what those were. Copper wire, of course, is what carried, you know,

landline, phone lines into our homes for many years. All of this is how motored by satellite and fiber

technology. And clearly that

communication, you know, Achilles heel, needs to be addressed quickly as we've seen at Newark.

So what technologies is Duffy talking about as a solution, at least by the year 2028, he's saying?

Well, some of the things you have to think about are replacing the radar systems.

These old radars, some of them are 50, 60-year-old technology, or 50- or 60-year-old radars, for that matter.

They have a built-in latency in them.

Some of them as long as 12 seconds before the whole radar to spin around.

That's what we're talking about here.
