 So this story, as is 4.30 this morning from CNN, all flights from several major U.S. airlines, including Delta, United, and American Airlines, were grounded this morning due to a communication issue, according to the FAA. The ground stop impacts all flights from the airlines, regardless of their destination. It's unclear how long the ground stop will last, though the FAA suggested an update would be available by 5 a.m. Eastern. So I'll keep trying to update these stories and also, of course, the Fox News feed.
