Oriana Pawlyk's Politico article reports that Transportation Secretary Sean Duffy blamed FAA contractor L3 Harris, questioning whether its months-long switch from copper wire to fiber involved user error or a faulty router, after the FAA ordered a nearly five-hour nationwide ground stop around 3:30 p.m. on Friday, 13 November 2026. Duffy called the FAA system one that "didn't meet the moment," and L3 Harris did not immediately respond to a request for comment.
