Why It Matters
This is the second time since the 9/11 terrorist attacks in 2001 that the United States has ordered flights to be suspended across the country. The last nationwide suspension of takeoffs occurred in January 2023, when the FAA suspended domestic flight departures in the United States for about 90 minutes. The U.S. air traffic control system has long faced difficulties such as equipment and communication problems, controller manpower shortages, and outdated infrastructure.
A communications failure occurred at the U.S. air traffic control center yesterday, forcing flights across the United States to suspend takeoffs for more than four hours. U.S. officials said today that the incident was caused by equipment failure or human error when a contractor was replacing old telecommunications lines at a remote facility; flights are expected to return to normal by the end of the week.
The Federal Aviation Administration (FAA) yesterday ordered a nationwide suspension of flights due to problems with the communications system. This is the second time the United States has ordered a nationwide suspension of flights since the September 11 terrorist attacks in the United States in 2001.
According to reports from The Washington Post and CNN, U.S. Transportation Secretary Sean Duffy said at a press conference today that the disruption to air transportation across the United States yesterday was caused by equipment failure or human error when contractor L3Harris personnel were trying to replace old copper telecommunications lines with fiber optics at a remote FAA facility.
He said whether it was human error or equipment problems, "we have not yet determined where the problem lies."
Duffy pointed out that this resulted in "more than 1,000 connection attempts every 4 to 5 seconds, which not only caused communication problems between us and the aircraft, but also caused some interference with our radar signal transmission."
As air traffic control centers resume normal operations, airlines are rescheduling pilots and flight attendants to absorb the backlog of flights. A large number of passengers' flights are still being delayed or canceled today.
Federal Aviation Administration Administrator Brian Bedford said that "the worst is over" and flights across the United States are expected to resume normal schedules by the end of the week.
Bedford pointed out that it is expected that of the approximately 41,000 flights scheduled for today, 4,000 to 5,000 flights may be cancelled.
He also said that the FAA estimated that a total of 12,000 flights were canceled yesterday.
According to foreign reports, yesterday's malfunction is the latest and most serious sign of the long-term pressure on the U.S. air traffic control system. The system has long faced equipment and communications problems, controller manpower shortages, and aging infrastructure.
