Drone near misses hit record high at major airports. Here’s what to know

A commercial airliner was on final approach to San Francisco’s international airport in November when the crew spotted a drone outside the cockpit window. By then it was too late “to take evasive action,” the pilots reported, and the quadcopter passed by their windshield, not 300 feet away.

A month earlier, a jetliner was flying at an altitude of 4,000 feet near Miami’s international airport when its pilots reported a “close encounter” with a drone. In August, a drone came within 50 feet of clipping the left wing of a passenger jet as it departed Newark International Airport.

The incidents were all classified as “near midair collisions” — any one of which could have had catastrophic consequences, according to aviation safety experts. They were also not isolated encounters.

An Associated Press analysis of an aviation safety database reveals that drones last year accounted for nearly two-thirds of reported near midair collisions involving commercial passenger planes taking off and landing at the country’s top 30 busiest airports. That was the highest percentage of such near misses since 2020, when air traffic dropped during the COVID-19 pandemic.

The first reports of near misses involving drones were logged in 2014, the AP found. The number of such encounters spiked the following year. Over the last decade, drones accounted for 51% — 122 of 240 — of reported near misses, according to AP’s analysis.

Passenger jets have long been subject to risks around airports — whether from bird strikes or congested airspace — as was made clear by the January collision between a military helicopter and commercial jet near Washington, D.C., that killed 67 people.

The threat has become more dire

The threat from drones has become more acute in the last decade as the use of quadcopters and remote-controlled planes has exploded in popularity. The FAA estimates that Americans are operating more than a million drones for recreational and commercial purposes.

“If you have the money, you can go on the internet and buy a pretty sophisticated drone that can reach altitudes they really have no business being at,” said William Waldock, a professor of safety science at Embry-Riddle Aeronautical University.

The risk is most acute near airports because that is where the flight paths of drones and airplanes most overlap, experts said.

The incidents represent only a portion of such close calls because the database — NASA’s Aviation Safety Reporting System — relies on voluntary submissions from pilots and other aviation workers. A separate FAA program, which includes reports from the public, tallied at least 160 sightings last month of drones flying near airports.

“The FAA recognizes that urgency, and we all know additional changes need to be made to allow the airports to go out and detect and mitigate where necessary,” said Hannah Thach, executive director of the partnership, known as Alliance for System Safety of UAS through Research Excellence.

FAA says it is taking steps to improve safety

The FAA said it has taken steps to mitigate the risks of drones. It has prohibited nearly all drones from flying near airports without prior authorization, though such rules are difficult to enforce, and recreational users may not be aware of restrictions.

The agency requires registrations for drones weighing more than 250 grams (0.55 pounds), and such drones are required to carry a radio transponder that identifies the drone’s owner and broadcasts its position to help avert collisions. Additional rules govern commercial drone use.

The agency has also been testing systems to detect and counter drones near airports. Among the methods being examined: Using radio signals to jam drones or force them to land. Authorities are also weighing whether to deploy high-powered microwaves or laser beams to disable the machines.

Experts said the FAA and other authorities could do more. They suggested creating a system similar to speed cameras on roadways that could capture a drone’s transponder code and send its pilots a ticket in the mail.

They also said the FAA should consider regulations that require all manufacturers to program a drone’s GPS unit to prevent it from flying near airports and other sensitive areas, a method called “geofencing.”

Drone manufacturer ends mandatory ‘geofencing’

DJI, a leading drone maker, used such geofencing restrictions for years. However, it eliminated the feature in January, replacing it with an alert to drone pilots when they approach restricted areas.

Adam Welsh, head of global policy at DJI, said managing requests from authorized users to temporarily disable the geofencing became an increasingly time-consuming task. More than one million such requests were processed last year.

“We had around-the-clock service, but the number of applications coming in were becoming really hard to handle,” Welsh said. “They all had to be reviewed individually.”

With no other manufacturers enabling geofencing, and without government rules requiring it, DJI decided to end the practice, he said.

The FAA declined to say if it is considering whether to mandate geofencing.

Drone users can face consequences

Experts said authorities should take more aggressive action to hold drone users accountable for violating restricted airspace — to highlight the problem and deter others from breaking the rules, pointing to recent arrests that they hoped might send such a message.

In December, for example, Boston police arrested two men who operated a drone that flew dangerously close to Logan International Airport. Police reported that they were able to find the drone flyers, in part, by tracking the aircraft thanks to its FAA-mandated transponder signal.

A month later, a small drone collided with a “Super Scooper” plane that was fighting wildfires raging through Southern California. The drone punched a hole in the plane’s left wing, causing enough damage that officials grounded the aircraft for several days to make repairs.

Authorities tracked down the 56-year-old drone operator, who pleaded guilty to a federal charge of recklessly flying his aircraft. The man, who has yet to be sentenced, admitted he launched his DJI quadcopter to observe fire damage over the Pacific Palisades neighborhood, despite the FAA having restricted drone flying in the area, according to court records. The operator lost sight of the drone after it flew about 1.5 miles from where he had launched it. And that’s when it struck the “Super Scooper.”
