Joe Rogan sat down with former Blink 182 member Tom Delonge to try and get him to explain his fascination with "aerial threats" or what we call UFOs.

Tom Delonge has been in the news a lot since he and Blink 182 parted ways. The UFO enthusiast has started a crowdfunding campaign to build a spaceship and has been outspoken about his belief in other lifeforms. While the idea may seem farfetched, he got enough support to raise over almost $1.8 million from over 1,400 investors. Delonge was recently a guest on the Joe Rogan Experience podcast and discussed what Rogan called his "obsession" with extraterrestrials. Delonge said he didn't want to call them UFOS or aliens or extraterrestrials but "aerial threats." He also discussed where his fascination with the aliens came from, his current work with the To The Stars Academy and what he hopes to learn from his research.
