"United Airlines' US Flights Temporarily Grounded Due to Software Update"

TL;DR
United Airlines briefly grounded all planes in the US due to a computer glitch caused by a software update, resulting in a widespread slowdown in the airline's technology systems. Flights already in the air continued as planned, and the issue was resolved about an hour later. The Federal Aviation Administration (FAA) confirmed the ground stop and stated that 211 flights were delayed. This incident follows a similar FAA computer outage in January that halted departures of all US flights for several hours.
