US officials are sending a drone-detection system to New York after a wave of mysterious sightings over the state and elsewhere along the east coast. Governor Kathy Hochul said she requested the federal support after drone sightings forced the closure of runways at Stewart International Airport for about an hour last week.

The deployment reflects growing pressure on the federal government to explain what people have been seeing in the sky. Reports have also come from New Jersey, Pennsylvania, Maryland, Connecticut and Massachusetts, while a separate sighting over Ohio led to a temporary shutdown at Wright-Patterson Air Force Base.

Hochul said state governments need more power to deal with the small uncrewed aircraft on their own and urged Congress to pass a law giving local authorities stronger tools. Senator Chuck Schumer added that he wanted a bill to give local law enforcement more power to investigate unidentified flying objects, while also calling for New Jersey to receive the same drone-detection help.

At the same time, federal officials have tried to calm fears. Homeland Security Secretary Alejandro Mayorkas said some of the reports involved drones, while others were actually manned aircraft that were mistaken for drones. He also said he knew of no foreign involvement in the sightings.

That message matters because the issue has escalated quickly from nuisance to national concern. Some lawmakers and commentators have suggested dramatic theories about the source of the objects, but the Pentagon has rejected claims that they were coming from an Iranian mothership. An FBI official said there may have been a slight overreaction.

Mayorkas also suggested that the apparent rise in reports could be partly explained by a change in federal rules that now allows drones to fly at night. If so, some of the increase may be visibility and reporting, not new hostile activity. Still, the public anxiety is real, especially when sightings are linked to airport disruptions and military bases.

The political pressure is also building because Donald Trump’s inauguration is approaching. His pick for national security adviser, Mike Waltz, criticised the Biden administration and said Americans would struggle to accept that authorities could not quickly identify the source of the aircraft.

The episode has turned into a classic federal-state coordination problem. Local officials want more authority, federal officials want to avoid inflaming fears, and the public wants a clear answer about whether the objects are drones, planes or something else entirely. For now, the government’s response is to deploy detection equipment while it continues to investigate what is actually in the skies.
