'CNN: FAA said to be unaware of real ground stop cause'

 The United States Federal Aviation Administration (FAA) "doesn't know yet what is going on" concerning a nationwide ground stop, CNN reported, citing a person familiar with the matter.

So far, US Department of Homeland Security (DHS) Secretary Markwayne Mullin and the FAA have claimed that the ground stop was caused by a telecommunications issue.

Meanwhile, another source told the outlet that the outage impacted air traffic control radars and radio frequencies, and that controllers were unaware of the root of the issue.
