With the suspension, almost 7,000 flights in the United States were delayed or canceled, according to data from the FlightAware monitoring website. United States Secretary of Homeland Security Markwayne Mullin said the problem is related to a temporary failure in telecommunications services. The US government reported that there is no reason for the population to be afraid.
The Brazilians are artificial intelligence engineers, work in São Paulo and went to the USA to participate in an event in the area in San Francisco, California, on November 8th.
In an interview with g1, engineer David Mannoel Lopes Rocha said that the group should return to Brazil on Thursday (12). The flight would leave San Francisco and head to New York, where passengers would connect to São Paulo.
During the journey, however, the pilot was unable to land in New York due to weather conditions. The aircraft was then diverted to Ohio, where the five disembarked at Cincinnati airport.
"Delta airline identified that there were five Brazilians and arranged accommodation in a hotel and rescheduled the trips for us. The new flight would be at 4:30 pm this Friday (13), destined for Orlando, from where we would continue to São Paulo", he says.
Just before boarding, however, passengers were informed that there would be a one-hour delay. The wait was long, and, according to David, the employees were unable to provide information about what was happening.
"It started to get longer and people started saying that they didn't know what was happening. The feedback was that they didn't know what was happening and no plane could take off", he reported.
Also according to him, passengers who had flights to Orlando were only able to travel on Saturday (14). People who already had their bags inside the aircraft were also trying to understand whether they could continue their journey. At the time of reporting, however, there was no official announcement of the flight's cancellation.

Until 9pm, the five Brazilians were still at the airport, with no confirmation as to whether they would be able to board that night or whether they would have to wait until the next day.
David described a tense scenario at the terminal, with long queues and passengers trying to resolve problems with the airlines. According to him, there were also people canceling flights, including travelers dressed as Disney characters who were on their way to Orlando.
"The atmosphere here is tense. Many long queues, passengers trying to resolve problems and people canceling flights. Among them, there are people dressed as Disney characters, who were on their way to Orlando. Everyone is tense," he said.

US President Donald Trump said the nationwide flight shutdown does not appear to be related to a cyberattack or AI. The FAA suspended all takeoffs after communication failures at air traffic control centers, affecting more than 10,000 flights. Anac monitors the situation in Brazil and Eurocontrol has suspended traffic from Europe to the USA.

The FAA suspended all takeoffs in the United States this Friday (13) due to a communication failure in air traffic control centers. The agency did not identify the cause or the affected equipment. The measure prevents takeoffs, but allows landings of aircraft already in flight. International flights are analyzed individually. The GAO had warned in September 2024 that 76% of the FAA's 138 technological systems had maintenance and sustainability problems, and reiterated the warning in September 2026 about modernization challenges. Congress approved $12.5 billion last year to modernize the communications system, and the FAA and White House requested an additional $30.1 billion before the shutdown.

Residents of the Mais Parque neighborhood, in Barretos (SP), have been reporting rumblings and night tremors for around two weeks. Civil Defense called the Brazilian Geological Survey for a field study while analyzing pipes and artesian wells with SAAE. Secretary Igor Santiago states that there is no history of earthquakes in the region and asks the population to remain calm.

A breakdown in FAA systems suspended takeoffs in the United States this Friday (13), causing delays and cancellations at Ronald Reagan National Airport, in Washington. Passengers, including American Candice Cage and Brazilian Amanda, face queues, held luggage and uncertainty about rebookings, while the federal agency has not yet predicted when the system will be normalized.

The Brazilian Air Force, through DECEA and CGNA, monitors the impacts of restrictions in United States airspace on international flights originating or ending in Brazil, with attention focused on Guarulhos International Airport. The government is evaluating adjustments to the flow of air traffic and, if necessary, directing aircraft to alternative airports.

The FAA suspended all takeoffs in the United States after a temporary telecommunications outage, leaving more than 11,000 flights delayed and more than 1,100 canceled. The FBI rules out hacker attack and investigates software flaw. Passengers report impacts at airports in the US and Brazil, including Guarulhos and Galeão.
