Numerous flights were rerouted and delayed following the FAA's warning about SpaceX rocket debris.

• After the SpaceX Starship rocket broke up, numerous flights were either diverted or delayed.
• The FAA issued a warning to pilots about the "risk of encountering falling debris from rocket Starship."

On Thursday, during its seventh flight test, SpaceX's Starship rocket caused several commercial flights to be diverted or delayed.

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

The Federal Aviation Administration temporarily slowed and rerouted planes near the location of a falling rocket debris from the Starship spacecraft after issuing a warning to pilots.

The rocket launched from SpaceX's Texas facility at approximately 5:30 p.m. ET and traveled eastward. However, it disintegrated, and SpaceX stated on X that they will analyze the data from the flight test to determine the cause.

No injuries or property damage have been reported to the FAA from Starship's debris, according to a spokesperson for the agency.

According to FlightAware, a JetBlue flight from Fort Lauderdale, Florida, to San Juan, Puerto Rico, was diverted back to Fort Lauderdale, two hours into the flight. JetBlue did not respond to a request for comment.

Flight-tracking data showed that a cargo jet and a Spirit Airlines plane both changed course near Turks and Caicos.

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

The issue resulted in less than 10 diversions for the carrier, according to a spokeswoman.

In the congested area around Florida, both commercial airlines and private planes vie for airspace.
