Air travel returns to normal
U.S. air travel returned mostly to normal Thursday, a day after a computer system that sends safety information to pilots broke down and grounded traffic from coast to coast.
By early afternoon on the East Coast, about 100 f lights had been canceled and 1,700 delayed — much lower figures than on Wednesday, when more than 1,300 flights were scrubbed and 11,000 delayed.
Attention turned to the federal agency whose technology failure inconvenienced millions of travelers.
The Federal Aviation Administration said a damaged database file appeared to have caused the outage in the safety- alert system. Transportation Secretary Pete Buttigieg promised a thorough examination to avoid another major failure.
“Our immediate focus is technical — understanding exactly how this happened, why the redundancies and the backups that were build into the system were not able to prevent the level of disruption that we saw,” Buttigieg told reporters.
Buttigieg said there was no indication that the outage was caused by a cyberattack but that officials would not rule that out either until they know more.
The FAA did not immediately respond to questions about the damaged database.
The massive disruption was the latest black eye for the agency, which has traded blame with airlines over who is inconveniencing passengers more. Critics, including airline and tourism leaders, say the agency has been underfunded and needs to modernize its technology.
“Investment is going to be required, no doubt,” American Airlines CEO Robert Isom told CNBC. “It’s going to be billions of dollars, and it’s not something that is done overnight.”
United Airlines CEO Scott Kirby has been critical of the FAA on a variety of issues, including staffing of air traffic controllers. He says the agency makes “a heroic effort” and does well most of the time but can be overwhelmed during busy travel times.
“They need more investment for technology,” Kirby said at a U. S. Chamber of Commerce event in September. “They have been saying it.”
Rep. Rick Larsen of Washington state, the top Democrat on a House aviation subcommittee, said the outage raises questions “about the current state of the technology infrastructure at the FAA.” He told CNN that Congress would consider whether the agency needs more money to modernize. wednesday’s breakdown showed how much American air travel depends on the computer system that generates alerts called NOTAMS — or Notice to Air Missions. Before a plane takes off, pilots and airline dispatchers must review the notices, which include details about bad weather, runway closures or other temporary factors that could affect the flight. The system was once telephone-based but moved online years ago.
Buttigieg said when the system broke down Tuesday night, a backup system went into effect. The FAA tried a complete reboot of the main system Wednesday morning, but that failed, leading the FAA to take the rare step of preventing any planes from taking off for a time.
