Tom DeLonge is offering his thoughts on the mysterious drone sightings in New Jersey.

On Saturday (Dec. 14), the Blink-182 guitarist and UFO aficionado shared a post on social media, proposing a theory about the mass drone sightings that have been reported across the Garden State in recent weeks.

“The drones that are being discussed, can hover for six hours, and then disappear once they are spotted,” DeLonge wrote on Instagram. “This is why it’s been hard to get facts from any US Agency. Some of them can even move into the ocean, and then back up to the air. Which is called ‘transmedium travel.’ A very hard thing to do.”

The drone sightings, which have also been reported in New York, Pennsylvania and Connecticut since late November, are currently under investigation by local, state and federal authorities, who remain puzzled by the flying objects.

On Friday (Dec. 13), White House National Security Communications Advisor John Kirby downplayed the sightings, suggesting that people may be misidentifying manned aircraft as drones, according to the New York Post. He also assured the public that there was no cause for concern. New Jersey Governor Phil Murphy reported nearly 50 sightings in the state alone just last week, NPR reports.

DeLonge, who has dedicated many years to researching and raising awareness about UFOs, compared the current sightings to mass UFO reports from the 1960s.

“There’s a strong possibility that these drones are ‘mimicking’ other aircraft,” the Blink-182 co-founder speculated, sharing a 1960s document about a military base that had “experienced a considerable number of reports of unidentified flying objects.”

He continued, “It’s all something to consider, and [although] we don’t have all the facts yet, we do know that UFOs play with ‘mimicry’ and that has been known for quite some time. Why? To get us to notice them without a major freak out? Who knows… but well, we are noticing nonetheless.”
