Air travel issues persist in the US after nationwide ground stop

Long lines and thousands of delays and cancellations due to Friday's ground stop of all U.S. flights, the longest in 25 years. The U.S. Transportation Secretary said that a contractor tasked with replacing copper wire with fiber in a remote facility produced an error that spread throughout the system, causing problems in radar and communications technology, though it was unclear if it was their error or faulty equipment. He also dismissed the possibility of malicious intent. We don't believe this was cyber at all. This was an FAA system that didn't meet the moment. Our contractor didn't meet the moment, or the equipment didn't meet the moment and cause the outages. Duffy warned of more disruption unless the system is updated, demanding $50 billion to improve it. Meanwhile, passengers are dealing with the fallout. With thousands of canceled flights, they're often sleeping in the airports. I've been here since 3 p.m. yesterday, and I honestly don't know what time it is now. I was flying to Vancouver, but it seems that now I'm flying to L.A. I had to work today, but I can't go back, so I'm not sure exactly what happened, but I just want to go home. A Federal Aviation Agency official said that air traffic is expected to return to normal by Sunday night.
