Several commercial flights were diverted or delayed Thursday after SpaceX's Starship rocket broke apart during its seventh flight test.

Dozens of flights were affected, according to flight tracker Flightradar24.

The Federal Aviation Administration said it "briefly slowed the aircraft and changed its course near the area where the spacecraft debris fell" after warning pilots about "the hazardous area where debris from the rocket Starship fell."

The rocket took off from the SpaceX facility near Brownsville, Texas, shortly after 5:30 p.m. ET, heading east from Texas. It was dismissed, with SpaceX saying on X that it would "continue to review data from today's flight test to better understand the root cause."

A spokesperson for the FAA told CNBC that the agency has not received any reports of casualties or property damage caused by the Starship wreckage.

one JetBlue Airways A flight from Fort Lauderdale, Florida, to San Juan, Puerto Rico, was diverted back to Fort Lauderdale after nearly two hours in the air, according to FlightAware, another flight tracking website. JetBlue did not immediately respond to a request for comment.

Other flights near Turks and Caicos Islands include fedex A cargo plane appeared to turn around, while a Spirit Airlines plane also changed course, according to flight tracking data.

The airlines and SpaceX did not immediately respond to requests for comment on the outage.

one American Airlines The spokesman said the airline had made fewer than 10 diversions due to the problem.

Delta Air Lines said it had diverted four flights to and from the Caribbean to other airports because of the debris warning.

Airlines and other commercial flights, as well as private jets, will compete for airspace, especially in congested areas around Florida, but the impact will likely vary by launch.

Qantas said it had to make last-minute delays on several flights between Johannesburg and Sydney in light of FAA advice on the return of SpaceX rockets to large swaths of the Indian Ocean.

Ben Holland, the airline's chief executive, said: "While we try to make changes to our flight schedule in advance, recent flight departure times have been advised in advance, meaning we have had to postpone some flights before departure. "Operations Center. "Customers generally agree that this is beyond the control of the airlines and that we cannot fly in this area when the rocket re-enters the atmosphere. We are contacting SpaceX to see if they can refine the flight area and time window. The rocket re-entry is To minimize future disruption to passengers on the route.”
