Federal authorities arrived in New Jersey on Friday to investigate whether the nighttime lights reported across the state since mid-November are drones on mysterious, malevolent missions or just aircraft mistaken for drones by a panicked public, Gov. Phil Murphy said Monday.

The governor, speaking to reporters at the Statehouse in Trenton, said he pushed the Biden administration to send drone experts to investigate — and so far they have found nothing alarming. Authorities do not believe public safety is at risk, he added.

“First of all, I would say, calm down. There is no evidence of anything nefarious here.” he said.

He added: “We never say never, but … take a breath.”

Murphy declined to describe exactly what the U.S. authorities were doing to investigate, he said only there is now three “very sophisticated systems” that “come with really sophisticated individuals” scanning the sky to determine what’s going on.

The systems has a range of up to 15 miles and will hop around the state until investigators have answers. Sunday night, they lined up at two locations – at state police headquarters in West Trenton and on Naval Weapons Station Earle in Colts Neck — and the governor and several FBI investigators joined them to observe, Murphy said.

While countless citizens have reported drone sightings, federal investigators “are not seeing much, if any, of that right now,” he said.

He admitted that the uncertainty is annoying. But he too took aim on elected officials who he said should be “calming influences” instead of fueling fears with speculation and conspiracy theories.

“There is zero evidence, with all due respect, that anybody is hiding the pea here, that the federal government or our military or anybody knows what’s going on here, and they won’t admit it. I see no evidence of that, he said. “There are a lot of conspiracy theories out there right now. Let’s put that one with the Iranians aside.”

US Rep. Jeff Van Drew (R-02) last week blamed on drone sightings of an Iranian “mother ship” off the coast earlier went back on friday (The Department of Defense denied his accusation).

Murphy attributed some drone reports to harmless hobbyists, noting that drones are affordable, legal and allowed to fly at nightwhile others are people misidentifying airplanes, helicopters, and other things manned aircraft as drones.

There are also more eyes in the sky, which likely inflated drone reportshe added.

“You also have the phenomenon of … 18 to 19 million eyeballs looking up at the sky every night,” Murphy said. “So there is a volume issuewhen it concerns just pure observations. I do it myself. We take the dog out. The other night I look up, and I am trying to figure out, is it a star? Is it an airplane? What is it? So I get it.”

He resisted labeling the public’s drone concerns as mass hysteria, saying: “It suggests that people are totally hearing footsteps and there’s nothing there. But me do think there is a big imbalance right now between the noise and reality.”

Still, residents in other states, including Pennsylvania, New York and Connecticut, have increasingly reported drone activity as well, he noted. Drone activity has also been documented near airports and military sites, critical infrastructure and President-elect Donald Trump’s Somerset County home.

So the drone mania is “a wake-up call” signaling the need for federal and state policymakers to tighten oversight of drones, he said. He urged the federal authorities to follow through legislation now before Congress that would give the Department of Homeland Security and the Department of Justice more authority over drones.

“We need better action on drones and drone strikes as a country,” Murphy said. “It’s extraordinary to me that a nation as big as ours and as powerful as ours has the failings that we’ve now seen, in living color, when it comes to drone strikes.”

Several state and federal lawmakers have criticized authorities’ response to the drone drama, saying the thousands of people who reported drones could not all be wrong.

Assemblyman Brian Bergen (R-Morris) said focusing on passing legislation is the “exactly wrong answer,” he added.

“We need to find out where these things come from right now. Like all the Governor’s resources, all his Laboureverything should be devoted to find out why they are there and what is happening right now. If you rush to politics, you will find out policy to is in a hurry“, he said.

Bergen was an Apache helicopter pilot in the military who served a year in Iraq. Investigating the source of the drones shouldn’t be much of a challengehe added.

“All you have to do is follow one—one!—back to wherever the hell it’s going and find out what’s going on,” he said.

Assemblyman Christopher DePhillips (R-Bergen) echoed calls for a federal investigation, saying the feds have authority over New Jersey’s airspace and the drones could pose a threat to national security. He introduced a resolution Monday called for such measures.

“The federal government must take decisive action and communicate its findings quickly and clearly to prevent those with ulterior motives from causing harm and copycat hobbyists from adding to the chaos in our skies,” DePhillips said.
