The FAA temporarily grounded flights in Dallas due to inclement weather and also to sanitize the operations center according to an article from the Dallas Observer published on December 30th. In it they say:
“The Federal Aviation Administration halted all arriving and departing flights out of DFW International Airport and Dallas Love Field Wednesday. The two airports announced the air traffic stoppage on their respective social media channels. The closures were in affect from 3 p.m. until around 5:30 p.m. and were in part due to bad weather and required sanitation at the FAA’s primary offsite operations center for the region in Fort Worth, a spokesperson for FAA said.”
The sanitation was necessary after an FAA employee tested positive for Covid-19 according to a Dallas Morning News article from December 30th. In it they say:
“A positive COVID-19 case at a key FAA air traffic control center in Fort Worth brought airline traffic to a halt at DFW International Airport and Dallas Love Field Wednesday afternoon. The FAA shut down all arriving and departing traffic at the two airports between 3:45 p.m. and 5:20 p.m., a period in which air traffic controllers were required to leave the control room and enact a ground stop at both airports.”
Truly, it must have been a hectic day at the FAA, what with the combination of a deadly disease and problematic weather.
