US Nationwide Ground Stops

Airlines have canceled thousands of flights across the U.S. as they work to recover from a nationwide ground stop a day earlier that left passengers scrambling for seats and disrupted travel around the world. The Federal Aviation Administration says U.S. air travel schedule should be back to normal by the end of Sunday, two days after what was the nation’s longest ground stop in 25 years. Transportation Secretary Sean Duffy is blaming a contractor that had been replacing a section of the air traffic control system’s old copper wire with new fiber wire. Duffy says that work somehow caused the system overload.
