The Federal Aviation Administration has issued a sharp warning that rocket launches could “significantly reduce safety” for airplanes, urging pilots to prepare for the possibility that “catastrophic failures” could create dangerous debris fields.
The official notice, known as a safety alert for operators, was dated Jan. 8, the same day that ProPublica published an investigation showing how pilots scrambled to avoid debris after two SpaceX Starship megarockets exploded over busy airspace last year. The alert was an acknowledgment that travelers were at risk on those days, when the FAA hastily activated no-fly zones to help air traffic controllers steer planes away from falling rocket parts.

In the last two decades, the agency has issued about 245 such safety alerts to the aviation community about issues ranging from runway threats to mechanical problems, but last month’s warning is the first to address the danger to airplanes when rockets launch or reenter Earth’s atmosphere, according to the FAA’s website.
SpaceX and other companies have ramped up launches in recent years. Starship, a version of which is supposed to one day land on the moon, has followed a flight path that soars over well-trafficked commercial airways in the Caribbean.
The FAA previously told ProPublica that it “limits the number of aircraft exposed to the hazards, making the likelihood of a catastrophic event extremely improbable.” It also said it takes steps to keep pilots informed and planes safe during launches, such as creating the emergency no-fly zones, known as debris response areas.
The January alert also pointed to those procedures.
“Past events have shown that when a mishap does occur, debris has fallen within or near the DRA, and pilots should exercise extreme caution near these areas,” the notice said.
But it warned that debris can fall in places where the FAA doesn’t enact no-fly zones, such as international airspace over oceans without radar coverage, saying pilots need to have “additional situational awareness” to avoid debris fields there.
Neither SpaceX nor the FAA has released data showing where debris fell after the Starship explosions last year.
SpaceX did not respond to a request for comment. Previously, the company has said that it learns from its mistakes and that each test improves Starship’s reliability. “SpaceX is committed to responsibly using airspace during launches and reentries, prioritizing public safety to protect people on the ground, at sea, and in the air,” it said on X in December.
Last year, the FAA granted SpaceX permission to launch Starship as many as 25 times a year from its base in Texas. But, after repeated setbacks, only five of the giant space vehicles lifted off in 2025.
In its warning, the FAA urged aircraft operators to “evaluate the impact of space launch and reentry operations on their planned flight routes and take appropriate precautionary measures.” Those should include ensuring they have enough fuel in case air traffic controllers put them in a holding pattern, the agency said. In its investigation, ProPublica found several airplanes began running low on fuel after the January 2025 Starship incident, with at least one declaring an emergency and crossing the no-fly zone to reach an airport.
The world’s largest pilots union told the FAA in October that such events call into question whether “a suitable process” is in place to respond to unexpected rocket mishaps. “There is high potential for debris striking an aircraft resulting in devastating loss of the aircraft, flight crew, and passengers,” wrote Steve Jangelis, a pilot and the group’s aviation safety chair.
The FAA adjusted its practices over the course of the failed launches last year but still allowed SpaceX to launch more Starship prototypes over the same airspace, adding stress to the already-taxed air traffic control system, ProPublica found. The Wall Street Journal reported in December that an air traffic controller needed to intervene to prevent a collision when at least two aircraft flew too close to each other after one of the explosions.
The FAA did not respond to requests for comment for this story.
Airlines for America, a trade association for the leading U.S. airlines, said it is “committed to ensuring the safety of all flights especially amid the growing number of space launches.” The association said in a statement that airlines coordinate with both the federal government and commercial space companies to make sure the airspace stays safe.
Rep. Nellie Pou of New Jersey, a Democrat on the House Transportation and Infrastructure Committee’s aviation panel, applauded the FAA for issuing the warning, saying the Trump administration “must protect American travelers from all threats, including space launches and reentry operations.”
“Perfect safety demands scrupulous and forward-looking attention to detail from our federal agencies and close coordination with operators,” Pou said. “I am heartened FAA is showing both here.”
ProPublica’s Jan. 8 story showed how airplanes had to maneuver quickly to clear wide swaths of airspace after SpaceX Starships blew up over the Caribbean in January and March last year.
Our analysis of flight tracking data found that in each incident, multiple planes were in the projected debris zones at the time of the explosions and that others likely had to change course to steer clear of falling debris. Pilots reported seeing flaming streaks far above the horizon.
Before the third Starship launch last year, in May, the agency settled on a more conservative approach, proactively closing more airspace ahead of time. That mission failed too, with the rocket’s booster exploding over the Gulf and its upper stage blowing up over the Indian Ocean.
SpaceX is now seeking FAA approval to add new trajectories as Starship strives to reach orbit. Under the plan, the rocket would fly over land in Florida and Mexico, as well as the airspace of Cuba, Jamaica and the Cayman Islands, likely disrupting hundreds of flights.
The company says it’s committed to public safety as it ramps up its launch cadence, saying in a post on X that it “will continue to ensure maximum public safety while also working to integrate Starship more efficiently into the airspace.”
