The young man who posted Elon Musk’s private jet coordinates has drawn the ire of Taylor Swift for tracking her private jet coordinates too (and posting her CO2 emissions), so Swift’s attorneys have handed him a pre-Super Bowl cease-and-desist letter.

Hey, remember that kid who was tracking Elon Musk’s private jet travel and posting those jets’ whereabouts? Musk referred to these locations as “assassination coordinates,” and banned the young man from Twitter/X. But that 21-year-old college student named Jack Sweeney is back on Twitter with an account called ElonJet but Delayed, which still posts those coordinates, but delays the information by 24 hours to avoid security risks.

Sweeney’s various social media accounts also track other rich-and-famous people’s private jets. And in the wake of recent concerns over Taylor Swift’s jet use and massive carbon footprint, particularly with her Tokyo-to-Vegas trip so she can continue her tour and still see the Super Bowl, Sweeney has started similar tracking of Taylor Swift’s private jets.  

And the Bay Area News Group reports that Swift’s team has sent him a cease-and-desist letter, saying they “have no choice but to pursue any and all legal remedies” and that Sweeney was engaged in “stalking and harassing behavior.”

“While this may be a game to you, or an avenue that you hope will earn you wealth or fame, it is a life-or-death matter for our client,” Swift’s attorney Katie Wright Morrone said in the letter. She added there was “no legitimate interest in or public need for this information, other than to stalk, harass, and exert dominion and control.”

But Jack Sweeney argues that flight path information is already public, and the information about carbon use serves a public good.

“This information is already out there,” Sweeney told the Washington Post. “Her team thinks they can control the world.”

“I think it’s important to note that nowhere do I intend for harm. I actually think Swift has some good songs,” he added, but also stressed that “I believe in transparency and public information.”

When Swift pulls her late-night flight from Tokyo to Vegas this weekend, it will cover about 20,000 miles. That translates to 200,000 pounds of carbon dioxide emissions, according to the Associated Press. For perspective, that outlet notes, “That would be about 14 times as much as the average American household emits in a year, according to data from the U.S. Energy Information Administration.”
