TRENTON, N.J. — A large number of mysterious drones have been reported flying over New Jersey and across the eastern U.S., sparking speculation and concern over where they came from and why.

New Jersey Gov. Phil Murphy and U.S. Sen. Andy Kim have both gone out on drone hunts, hoping for answers. The FBI, Homeland Security, state police and other agencies are investigating.

Murphy and law enforcement officials have stressed that the drones don’t appear to be a threat to public safety, but many state and municipal lawmakers have nonetheless called for stricter rules about who can fly the unmanned aircraft — and to be allowed to shoot them out of the sky.

Federal authorities said Monday evening that the sightings have included legal commercial drones, hobbyist drones and law enforcement drones, as well as manned aircraft, helicopters and even stars mistakenly reported as drones. Officials said that assessment was based on tips and technical data.

What’s the Deal With the Drones in New Jersey?

Dozens of witnesses have reported seeing drones statewide since mid-November, including near the Picatinny Arsenal, a military research and manufacturing facility, and over President-elect Donald Trump’s golf course in Bedminster.

Murphy, a Democrat, said Monday that equipment supplied by the federal government has yielded little new information. He declined to describe the equipment except to say it was powerful and could even “mitigate” the drones, though he added that’s not currently legal on U.S. soil.

Murphy urged Congress to give states more authority to deal with the drones.

Meanwhile, the FBI and New Jersey state police warned against pointing lasers at suspected drones, because aircraft pilots are being hit in the eyes more often. Authorities also said they were concerned about people possibly firing weapons at manned aircraft mistaken for drones.

Do the Drones Pose a Threat?

The growing anxiety among some residents is not lost on the Biden administration, which has faced criticism from Trump for not dealing with the matter more aggressively.

White House national security spokesman John Kirby on Monday said the federal government has yet to identify any public safety or national security risks from reported drone sightings in the northeast, saying officials believe they were lawfully flown drones, planes or even stars.

“There are more than 1 million drones that are lawfully registered with the Federal Aviation Administration here in the United States,” Kirby said. “And there are thousands of commercial, hobbyist and law enforcement drones that are lawfully in the sky on any given day. That is the ecosystem that we are dealing with.”

The federal government has deployed personnel and advanced technology to investigate the reports in New Jersey and other states, and is evaluating each tip reported by citizens, he said.

About 100 of the more than 5,000 drone sightings reported to the FBI in recent weeks were deemed credible enough to warrant more investigation, according to a joint statement by the Department of Homeland Security, FBI, Federal Aviation Administration and the Defense Department.

Who Is Operating the Drones?

Authorities say they do not know.

Speculation has nevertheless raged online, with some expressing concerns that the drones could be part of a nefarious plot by foreign agents.

Officials stress that ongoing investigations have found no evidence to support such concerns, but U.S. Rep Chris Smith, a Republican, on Saturday echoed such speculation.

“The elusive maneuvering of these drones suggests a major military power sophistication that begs the question whether they have been deployed to test our defense capabilities — or worse — by violent dictatorships, perhaps maybe Russia, or China, or Iran, or North Korea,” he said.

On Monday, Pentagon spokesperson Maj. Gen. Pat Ryder cast doubt on the idea that the drones are engaged in intelligence gathering, given how loud and bright they are.

Pentagon spokeswoman Sabrina Singh has said the aircraft are not U.S. military drones.

Drone Operators Arrested

In Boston, city police arrested two men accused of operating a drone “dangerously close” to Logan Airport on Saturday night.

Authorities said an officer using drone monitoring technology detected the aircraft and the location of the operators. A third man fled police and remains at large.

Authorities said the two men face trespassing charges and could face more charges and fines.

Ohio Air Force Base Closes Airspace

Drones flying around Wright-Patterson Air Force Base near Dayton, Ohio, forced base officials to close its airspace for about four hours late Friday into early Saturday, said Robert Purtiman, a base spokesperson.

It was the first time drones had been spotted at the base, one of the largest in the world, and no sightings have been reported since, Purtiman said Monday. He said the drones had no impact on any facilities on the base.

Officials Urge Action Against the Drones

Trump has said he believes the government knows more than it’s saying.

“Let the public know, and now. Otherwise, shoot them down!!!” he posted on Truth Social. Kim said he’s heard no support for the notion the government is hiding anything. He said a lack of faith in institutions is playing a key part in the saga.

“Nothing that I’m seeing, nothing that I’ve engaged in gives me any impression of that nature. But like, I get it, some people won’t believe me, right? Because that’s the level of distrust that we face,” Kim said Monday.

Sen. Richard Blumenthal of Connecticut last week called for the drones to be “shot down.”

Monmouth County Sheriff Shaun Golden said members of the public must not try to shoot down drones, as that would violate state and federal laws.

Drones Spotted Over New York City

Drone sightings were also reported in New York, where a permit is required. Mayor Eric Adams said the city was investigating and collaborating with New Jersey and federal officials.

The runways at Stewart International Airport — about 60 miles (100 kilometers) north of the city — were shut down for about an hour Friday night because of drone activity, Gov. Kathy Hochul said.

“This has gone too far,” she said in a statement.

The governor called on Congress to strengthen the FAA’s oversight of drones and give more investigative authority to state and local law enforcement.
