FAA ground stop: the air traffic network that failed is one the FAA said in August could no longer cope
The US nationwide ground stop on 13 November was blamed on old routers. But officials say the FAA’s air traffic communications backbone, run by L3Harris, broke while it was being upgraded, and in August the FAA itself wrote that the network could no longer adequately support air traffic. The $50bn Sean Duffy wants does not close that gap.
